NOTAS DE CAMPO: HEMBRA DE MANGO PECHINEGRO - FEMALE BLACK THROATED MANGO ( Anthracothorax nigricollis)

VUELO DE APROXIMACIÓN AL BEBEDERO DEL MANGO HEMBRA
(Anthracothorax nigricollis)

Sigo trabajando en el desarrollo de técnicas para fotografiar y entender el vuelo de los colibríes. En este momento, tengo la fortuna de contar con la visita de una hembra de Mango Pechinegro, que viene visitando el bebedero de la ventana de mi cuarto desde hace 2 meses. Creo, que los embates del verano han servido, para que se sume a las tres especies que visitan a diario este recurso inagotable de néctar...el bebedero es clave, mientras el bosque seco tropical permanece desnudo de hojas, en un estado de letargo, que aparenta la muerte del mismo y no es más, que una respuesta de las plantas al estrés causado por la escasez de agua.

La llegada de este colibrí ha incrementado el conflicto territorial entre las tres especies y me parece increible que los Amazilias (fimbriata y tobaci) acosen de tal manera a la recien llegada, que los supera en tamaño.

Las cuatro fotos de arriba son parte del estudio fotográfico que le estoy haciendo a esta nueva especie en mi área de trabajo, con el fin de aprender, si su tamaño es limitante a las pericias demostradas en picados, volar barriga arriba, girar, subir casi en vertical y otra cantidad de acrobacias propias de los Amazilias.

Espero que disfruten de las imágenes y los mantendré informados.

Hasta la próxima nota de campo, reciban un cordial saludo.

LA IMPORTANCIA DE LOS COMEDEROS PARA FOTOGRAFIAR AVES: PEGONCITO PARQUE DE COLIBRÍES


INTRODUCCIÓN:



Como fotonaturalista trato de hacer archivos que me sirvan para muchas cosas, tales como: Publicaciones en revistas, libros, folletería, catálogos y actualmente, en Internet. Sin embargo, no siempre se tienen las imágenes adecuadas para una publicación y cuando nos solicitan un artículo con sus respectivas imágenes, por más que salgas a hacer archivos, te pueden faltar las fotos. Eso me ocurrió a mi recientemente y casi me cuesta el trabajo. Pensaba, que tenía suficientes fotos de unos pájaros, que en Venezuela, llamamos Azulejos y no las tenía todas.

Mi primer problema fue tener una foto en vertical, que se necesitaba para la ficha de promoción del artículo, y la que tenía, no era del tamaño adecuado. El primer consejo, que me dieron en mi clase de fotografía periodística en la universidad fue: Acostumbrate a realizar tus imágenes haciendo fotos en vertical y horizontal del mismo objetivo. Sucede, que a los editores les gusta, contar con las dos opciones, con el fin de tener flexibilidad al momento de trabajar el diseño de lo que van a publicar. Puedes tener una foto maravillosa, pero sino encaja en el diseño, no va. Y si el editor se enamora de la imagen y esta fue realizada en algún lugar remoto o en unas condiciones irrepetibles, la frustración del mismo, puede ser crítica al momento de escoger nuestros trabajos en el futuro. Así que es mejor, no dejar al azar nuestros requerimientos de trabajo. Hay que repetir las imágenes, hacerlas desde varios ángulos y encuadres y nunca, cuando nos encontremos con algo que sobre salga, dejemos de hacer una serie del objeto a fotografiar.

Ser cazador de imágenes requiere un conocimiento profundo de nuestros objetivos. Y al tratarse de animales, conocer sus hábitos, es la primera cosa que nos ayuda para asegurar el éxito de nuestro trabajo. Si queremos disponer de un lugar seguro para encontrar a los pájaros que necesitamos, búscalos donde comen. Sin embargo, la comida en la naturaleza, no se encuentra en el mismo lugar todo el tiempo. Pero para esto hay una gran solución. Habituar a la vida silvestre a beber y comer en el mismo lugar todos los días, y esto se logra, creando un ambiente propicio para ello. 

Como el caso que nos ocupa son aves, recurrí a la ayuda de mi colega Tomás Fernandez, el creador de PEGONCITO PARQUE DE COLIBRÍES. Tomás tiene años fotografiando colibríes y como amante y estudioso de estas aves, se ha dado a la tarea de hacer del jardín de su casa, un paraíso para sus visitantes alados. Todo, lo sembrado en el jardín, esta en función de las aves que lo frecuentan. Allí encuentran comida y refugio. Tomás conoce  los horarios de visita y las fechas de las migraciones que los pájaros pasan por su jardín. 

Elaborar comederos no es difícil y además , resultan fáciles de construir utilizando material de reciclaje. Desde fondos de botellas plásticas hasta recortes de bambú pueden convertirse en comederos, bebederos y hasta baños para las aves. Se recomienda utilizar alimentos naturales dependiendo de los pájaros que quieran atraer a sus casas. Recuerden que hay pájaros semilleros, fruteros, insectivoros y hasta nectívoros, que se alimentan del néctar de las plantas y cada uno tiene sus dietas específicas. Los comederos se pueden fabricar acorde con el alimento que llevaran dentro de ellos. La profundidad, altura, diámetro y hasta el color son importantes para su confección.

EL AZULEJO DE JARDÍN / TÁNGARA AZULEJA / BLUE-GRAY TANAGER 
(Thraupis episcopus)

El Azulejo de Jardín se encuentra desde México hasta el sur de Brasil. Es un ave que vive muy bien tanto en los bosques como en las zonas urbanas, donde la proliferación de jardines y la siembra de árboles frutales o plantas con flores ricas en néctar, les proveen un sustento mas predecible que en las zonas naturales. Estas aves patrullan en pareja sus territorios y no es difícil saber cuando esperarlos, si se los tiene acostumbrados a visitar un comedero a ciertas horas del día. Además, su naturaleza curiosa permite que el fotógrafo pueda atraerlos al alcance de sus lentes ofreciéndoles cambures (Bananos, guineos o platanos), naranjas o papayas. Una vez se acostumbran a la presencia de sus benefactores se les puede fotografiar a gusto.


SEMBRANDO COMIDA "EL COMEDERO NATURAL"

En las siguientes dos fotos, verán a los azulejos tomando néctar, comiento flores y frutas de la misma palma Areca.


Al recorrer sus territorios los pájaros se hacen de una memoria estacional de los recursos alimenticios que tienen y en muchas instancias, se convierten en polinizadores y dispersores de semillas. En el caso de los Azulejos de Jardín, estos visitan tanto a los frutales como a los comederos que se distribuyan por el jardín y no es raro que una pareja visite durante el día a varios jardínes si se los alimentan bien.


Si se fijan con detenimiento, verán, que al fondo de la foto, apenas se ve otro racimo de frutas de palma, empezando a madurar. Esto quedará en la memoria de los azulejos quienes seguirán visitando el jardín mientras hayan frutas para comer. Las palmas Areca duran cerca de tres meses entre su floración y la maduración de las frutas, así que esto garantizará la visita de aves por largo tiempo a los jardines.


Este es un comedero confeccionado de una rama de bambú y alambre suave. Al cortar al bambu longitudinalmente, quedan expuestos los huecos que se forman entre los nódulos y con un pedazo de bambú de dos segmentos pueden poner agua en uno y frutas en otro.


EL PROCEDIMIENTO: Una vez llegaron los azulejos y otros fruteros al comedero, retiramos los bananos de el y lo amarramos en un lugar con mejor luz. Posicionamos la comida en forma que los pájaros se acercaran a ver que era y esto nos dio tiempo para pre-enfocar y asegurar la exposición correcta para fotografiarlos. Es importante notar que para lograr las fotos teníamos que acercarnos progresivamente a los pájaros, hasta un poco antes, de su distancia de fuga, que es la distancia mínima, que un animal deja que se le acerque un depredador, antes de emprender la huída. Una vez el respeto por el espacio del animal se lograba, este comía más seguro y se dejaba hacer las fotos hasta con flash de relleno.

AZULEJO DE PALMERA-TANGARA DE PALMA / PALM TANAGER 
(Thraupis palmarum)

El Azulejo de Palmera tiene una distribución menos amplia que la del Azulejo de Jardín. Sus hábitos son parecidos a su pariente azul, pero estas aves le deben su nombre a la manera acrobática que exploran las palmas en busca de insectos y arañas. Se cuelgan cabeza para abajo para buscar los insectos que duermen refugiándose del sol y de la lluvia en el  envés de las hojas de palma.


Estos llegaron al comedero después de que los azules se fueron ya que los azules tienden a ser muy pendencieros, al proteger las frutas de las que se alimentan. En conducta animal esta conducta se llama orden de picoteo o jerarquía de dominancia y subordinación. Por eso es bueno dedicarle cierto tiempo de observación al comedero, ya que esta jerarquía funciona todo el día y con todo tipo de animales. Y mientras más aprendemos sobre nuestros objetivos, mejores serán nuestras oportunidades de hacer buenas imágenes.


Tras observar al fotógrafo y a los otros pájaros este bajo al banano y comió despreocupadamente, pero escondiéndose del fotógrafo ubicándose detrás de la rama.


Conclusiones: Si se vive en una casa o apartamento con balcón donde se puedan tener plantas, sembrar, las que atraigan a las aves que quiere fotografiar es una práctica maravillosa. Si se va a habituar a la vida silvestre a comederos, deben ser responsables de su abastecimiento, limpieza y reparaciones. Hay que seguir las normas de buena vecindad previendo que los animales que vengan a nuestras casas no se conviertan en problemas para los vecinos.  Así que para disfrutar la fotografía con comodidad, las alternativas de alimentar en forma natural o con comederos a nuestros vecinos silvestres les darán años para entretenerse y realizar muy buenas imágenes.

CELFONTOGRAFIADO UN BOSQUE NUBLADO PARTE 1


El reto que representa hacer un trabajo fotográfico dentro de un bosque tropical es considerable para cualquier fotógrafo. La luz se presenta en claros oscuros múltiples que hacen difícil obtener una exposición optima.El terreno es irregular, la visibilidad es limitada y hay tantas cosas en nuestro entorno, que se nos hace complicado escoger que fotografíar. Además, el paisaje, no es un paraje abierto con planos claramente definidos, así que documentar un bosque requiere paciencia y tiempo. Es por esto, que cuando queremos fortalecer el punto, de que cualquier cámara funciona para hacer fotografía, siempre hay que conocer sus capacidades y limitaciones. 

Así que utilizar las cámaras telefónicas para este tipo de trabajo, es poner a prueba una nueva tecnología a través de viejas mañas. Las cámaras telefónicas están en franca competencia con las compactas y la falta de un dial de modos fotográficos, que avanza hacia el desuso, esta siendo compensado por programadores, que se dan a la lucrativa tarea de crear applicaciones, que a .99 centavos de dolar, se venden a millones de personas en internet y le permiten a las cámaras telefónicas realizar hazañas que solo se limitan por nuestra imaginación.



Me confieso uno de los tantos fotógrafos que se decia que nunca iba a tomar fotos con una camarita de juguete, y las hice, luego manifesté que jamás tomaría fotos con un teléfono pero todo cambia muy rápido y como nunca salgo sin mi cámara telefónica, la fotografía instantanea, ya es parte de mi vida. Pero si me preguntaban hace tres meses, si usaría una cámara telefónica para hacer fotos de la naturaleza, me reiría hasta diciembre de este año. Así, que como van las cosas, no les estrañe, que me dedique a leer vehementemente sobre cámaras Android, las Go Pro y aplicaciones que me permitan hacer fotografías WiFi con mi teléfono usando Live View, mientras hablo con amigos por el celular. Ahora, no es raro, que me ponga a pensar, en lo que haría si pudiera comprar toda la nueva tecnología y ponerla al servicio de mi imaginación. Pero vamos al grano, la fotografía con cámaras telefónicas en áreas silvestres.

La foto de arriba es una panorámica, tomada al mismo instante, en que me vino a la mente como enseñarles a todos, que con dos clicks, uno de inicio y otro para finalizar, obtendría la foto que me permitiría enseñarles lo que es una panorámica dentro de un bosque tropical. Además también puedo demostrar como maneja el sensor de una cámara telefónica, las fotos que nos proponemos realizar.



Esta claro, que el rango dinámico entre las sombras, los tonos medios y los zonas con mucha luz, no es fácil de manejar, con ninguna cámara, pero creo, que podemos acostumbrarnos a ver fotos como la de arriba. Desde el punto de vista de un naturalista, la foto documenta como las plantas compiten por la luz en cualquier bosque, aquí hay plantas de sombra, otras que buscan la luz en los estratos medios del bosque y luego están, las que conquistaron el tope favoreciendose de la mayor cantidad de luz que el sol nos puede dar. Manejarse adecuadamente entre sombras, tonos medios y sobre-exposición, son factores que en la vida natural de las plantas, y que en biología se llama  fototropismo. Esto se puede explicar bastante bien con esa foto. Creo que para expresar el contenido documentalista de esta imagen, la cámara telefónica cumplio su objetivo.


A escasos metros de distancia, hice la foto de arriba, justo al borde superior de una quebrada. En las quebradas, el agua manda, y por donde ella corre, son pocos los árboles que no se caen a su paso. En consecuencia, hay una entrada de luz mayor, al suelo del bosque, y al tomar la foto temprano en la mañana, los tonos medios se favorecieron, así que en esta imagen, se ven diferentes tonalidades de verde, el color de los troncos de los árboles y hasta los del suelo de la selva. Para lograr esto , mantuve al cielo fuera de la imagen, con el fin, que ésta no saliera lavada. Una vez más la opción panorámica de la cámara, que vino incluida con el teléfono, funcionó para mi. No hay duda alguna de la biodiversidad de este bosque, donde cada espacio es, o va a ser ocupado, por algún tipo de vegetación, que está adaptada al lugar preciso en donde crecen, la luz juega un papel determinante sobre las las plantas y las obliga, a crecer según sus necesidaes de supervivencia. Esto queda en evidencia en la imagen, al captar un todo, que ilustra, como se distribuye la vegetación en este tipo de bosque. 



En la foto de arriba, que es un contrapicado, o una foto realizada de arriba hacia abajo, siguen mandando los tonos medios. Las hojas verdes de helechos, palmeras y calatheas dan reflejos plateados, cual rebotadores, reflectando el exeso de luz, mientras que las hojas en la sobra, registran un verde oscuro. Como se vería la copa del árbol... con muy poco detalle, porque al apuntar la cámara hacia ella solo tendría una silueta y mucho blanco. Así que al ajustar la fotografía a las capasidades del sensor de la cámara, se pueden lograr imágenes que se ajusten a lo que queremos documentar.


¿Como puedo hacer evidente la presencia de las palmas del bosque sin fotografiarlas desde el suelo hasta la copa? Pues, usando la opción panorámica de nuevo y fotografiando el suelo. La luz que penetraba hasta el suelo era bastante uniforme y permitía destacar so que habia sobre éste. En la imagen hay mucha información sobre lo que ocurre en el bosque, por ejemplo: Hay palmitas germinando en la parte inferior de la fotografía, a la izquierda de la foto, se puede ver un racimo de frutas seco, en el medio, las vainas de una hoja y de la inflorescencia que sostenía a las flores y frutos de la planta, que se suman como evidencia, para revelar la existencia de palmas en ese lugar. Finalmente, en la parte superior de la imagen, se puede ver un poco de un tronco, del cual salen múltiples raíces, y que nos da la ubicación de la palma de la cual salieron todas estas manifestaciones. No está mal, para ser fotografías hechas con un teléfono...



Para forzar más la barra, un foco de luz que caía sobre el tronco de un árbol muerto, que le daba sosten, a un pequeño manto de musgo, atrajo mi atención. El verde del musgo es mágico, siempre he tenido gran admiración por una de las primeras especies de plantas verdes que colonizaron tierra, mucho antes que los dinosaurios y que además, estaba reproduciendose. Para esta foto pegué el teléfono al musgo y enfoqué el borde, donde las cápsulas reproductivas se veían mejor por tener un fondo oscuro. La posición de la cámara era incómoda, pero para hacer esto con una refex, tendría que acostarme sobre el suelo. Aumenté al 100% una parte de la imagen para destacar a las cásulas y ahí termina la historia de como fotografiar el musgo con una cámara telefónica.



Soy de los que cree que la estética no es privativa de la fotografía para documentar el entorno natural. Si bien es verdad que el uso de rebotadores o flash de relleno permitirían ver mas el sotobosque. Exagerar las limitaciones que las cámaras telefónicas tienen, ayuda a expresar el sentimiento que da caminar entre luz y sombras.



Cerca del medio día, la luz es cenital, y es el único momento del día, en que la misma tiene mayor penetración hacia el suelo del bosque. Sin embargo, el relieve no sabe de movimentos del sol y las plantas que nacen sobre el suelo del bosque, viven un juego de azar donde la vida o la muerte son las únicas alternativas. Así que buscar la luz y optimizar los medios para captarla, es su única opción. Metafóricamente hablando buscar la iluminación y salir de las sombras es una gesta real de la naturaleza y ni el hombre, ni el fotógrafo se escapan de eso. 


Espero que esta aventura con cámaras telefónicas los inste a usarlas y traten de crear sus propios estilos, en mi caso, fue un ejercicio de mantenerme en los tonos medios y usar los altos contrastes para resaltar la vida en la parte más baja de un bosque nublado. Para la próxima entrega de Celfotografiando nos vamos para los detalles. Se les agradece comentarios y sugerencias para artículos.

Pásenlo bien y nos encontramos en la pantalla.

Todas las imágenes fueron realizadas en el Bosque de la Virgen de Jardines Ecológicos Topotepuy quienes siempre me dan la facilidad de fotografiar a la naturaleza en un lugar seguro donde los fotógrafos se pueden tomar el tiempo para hacer fotografía a su antojo mientras la familia lo pasa muy bien.

SMARTPHONTOGRAPHY IN THE CLOUD FOREST PART 1


KNOWING WHAT WILL WORK FOR US IN SMARTPHONETOGRAPHY

The challenge of light in any forest is tremendous for the nature photographer and when one wants to make a point, that smartphonetography can serve as a useful tool for documentary work, the issue becomes on how far can a photographer go with a smartphone to get the images required for the job. 

A camera-phone is the brilliant substitution of the point and shoot digital camera, if one can do without a mode dial with up to 50 scene types of shooting situations. However, programers are making software/applications to bypass these hurdles. I am, a learning owner, of an Iphone with limited access to innovating apps so, in essense, as most newbies, one most make do with what we have. So all the pictures in this article were taken with the default Iphone Camera. As limitation is the mother of innovation, this can be a good thing, as it forces you to use your "BIG CAMERA" skills to circumvent the cameraphone's limitations.


As the article is about the cameraphontography of a cloud forest, the photo above shows part of a transcition forest which will be the shoot's location. Please note at the top right where an overexposed spot can be seen breaking through the canopy, while in the rest of the panorama, the midtones are quite even. This is a small example of getting into context and learning, what the landscape, vegetation and light offer to the visiting photographer. It hints the limitation and capabilities of you camera, thus helping the photographer predict what works and what doesn't.


When the views of the forest are from top to bottom, the light filtering through the forest gap changes the green color of the leafs to a silvery reflection, and the information rendered the shadows with little details. Note that the earth colors (midtones) were registered well by the Iphone's sensor. So in essence, as long as we stay within the midtone rage on the forest's light, we will be in good shape doing nature photography with a smartphone, but what about pushing the limits. Well, sometimes it works (with pos production help), and others it doesn't.


Starting from the ground up, which is what most of us do. Many nature photographers like to document the minute world of the forest. Here, as little spots of light fall upon the ground, it gives the photographer opportunities to document, those little miracles that light provides to living things once it reaches the forest floor, in this case, a moss blanket with its reproductive capsules visible. I augmented the insert 100% in order to show you, how far can the Iphone allow an image enlargement. Please note that the camera-phone has a very shallow DOF, and this are the things, that one could improve with a macro lens, a high f/stop and the camera set on a tripod so you can trigger it with a cable release. However, as you can see here, if your work is online, you can have some latitude to get away with your cameraphone pictures for an internet publication.

WALKING IN THE SHADOWS

The understory is to the forest what the bottom of the sea is to the oceans. It has been found that only 2% of the sun light reaches the forest floor at noon time. This knowledge has fasinated me all my life. To think that a tiny spotlight that reaches the forest floor, for a certain amount of time during the day, would trigger a seed's germination, which will turn into a giant that will be over 100 feet tall, live up to 1.000 years, and weigh several tons, is just fantastic. But the struggle, that plants undergo to get the proper light in order to survive in the forest, surpaces our imagination, and it becomes evident, the very moment, that you decide, to do a shoot under the canopy of any forest.


A walk in the shadows with a cameraphone that can do panoramics in an instant enables the photographer to sweep from well lit places to the shadows like no DSLR can. There is no multiple photo sequences, pan heads, tripods, and pos processesing stiching and fine tuning involved. There will be areas in the photo that will be overexposed or too dark, however, that serves the purpose of explainig, how light is presented to the photographer by the surroundings.


Frankly, I find the extreme lighs and shadow areas very pleasing, as they trully express the feeling one gets while walking in the shadows of the cloud forest, where the light range becomes a great subject to document the true nature of your place of work. Can a cameraphone get the job done, I'll let you be the judge of that.


I encourage everyone to pay close attention on how plants seek the light, how their structures and arquitechture increase their potential to light gathering, and how you can exersice your light awareness if you try to so several shoots in the understory of any forest.

Let me invite you to another cameraphone/smartphontography adventure when I will, take on the vertical region between the ground and the canopy of the forest as the next Digital Camera Adventure.

All the pictures were taken at a small part of the cloud forest relict, of Bosque de la Virgen, in  Caracas, Venezuela. Which is under the custody of Jardines Ecologicos Topotepuy, the sponsor of this article and the one to follow.

UNDER THE SPOTLIGHT


INTRODUCTION

To most people, been under the spotlight is to stand out from everything. In the visual arts, the term refers to the use of artificial light to make someone or something stand out from a scene. For us, it will take a whole different meaning. I like to invite you to go to the closest wooded area near your home, and spend at least 4 hours walking off the trail, or if all you've got is a park, well, look beyond the trail and pay close attention on how the sunlight breaks through the canopy onto the forest floor. Now, each of the sun ray that  gets through the canopy becomes a spotlight, however, in nature, been under the spotlight can be a matter of life and death, as light is an important component for photosynthesis, which is a key function in green plants' life.

I have been hunting spotlight pictures for a while in the cloud forest of Bosque de la Virgen, South of Caracas the capital city of Venezuela. I was surprised by the fact, that to a lot of trekkers and nature photographers, the subject has not attracted their attention. But as it turns out, once one grows awareness towards this natural occurrence, this source of light becomes an important subject for pictures about life and beauty in the understory of the forest. I feel it is very important for an image hunter to be one with nature. Opening our senses to our surroundings will help us feel what goes undetected to most. Pausing and studying a tiny spot of light reaching the ground may seem of little value, however, in nature, nothing is meaningless. So allow me to show you some information about the importance of been in the spotlight in a tropical forest.


I took out the color of these Peace Lilies to make a point. To show you wonderful kind of beauty found in the light range, between total darkness and outright brilliance coming from nature's spotlight, and once you learn to see it, your photographic subjects will increase exponentially during your photo outings.

THE ESSENCE OF SPOTLIGHTS

People know that the sun travels above the sky from east to west every day. At day break and sunset, it is near the horizon, and at noon, it will me in the zenith of the sky and its ray will be shinning directly over head. The rest of the day the angles of light change by the hour and this will influence how nature's spotlight reaches within the forest.


The pictures above were taken at 16:15 at ISO 800, f/6.3, and 1/250. The were taken almost at the same angle, as the lily patch was at the same level in the slope of the hill where I found them. I tried to single out each inflorescence in a way that the background would be shaded. Then, I underexposed the flower to bring out the details in the white parts of the flower and the results were very pleasing. Note that there is no noice noticeable, the high ISO enabled me to take the picture without the use of a tripod and using a cable release on the camera to attain maximum sharpness. Though, I strongly recomend the use of tripods, I was not planning to do this series, so I left both things at home. The use of large lens openings allows for great bokeh and if the background is in the shade, darkening it in pos production gives beautiful results.

I am sure, that if you would take it upon yourself to photograph Spotlight in rural or urban settings, your portfolio would end up with a beautiful collection of photographs.

FROM THE GROUND UP

Most plants grow from the ground up. They start as seeds, then germinate and soon as this happens, their rudimentary leafs move towards sunlight as fast as they can. In the picture below, a seedling germinated between the roots of a forest giant. The spotlight fell upon it from the same direction, and thus, it was placing most of its growing effort towards the direction where the light broke through the canopy into the forest floor. For a nature photonaturalist aesthetics and content are importan, as her/his efforts most involve, the intended audience that will seek either a nice photograph or a photographic document for a publication.


In tropical forests, leaf color can be a key for the photographer who is seeking plant growth. And when one combines leaf color with spotlight occurrences, finding photo opportunities will get easier.





THE MIDDLE TIER

When one sets out to search for spotlights in the forest, don't restrain your search to ground level. Look up to the middle tier of the forest, as it is the connecting area between the understory and the canopy and many amazing things are constantly happening there. Backlit objects are a common ocurrence in this part of the forest. In fact, many vines make their life in this region, growing and very fast rates from one canopy gap to the other seeking spotlights as they grow. Unlike lianas and other woody climbers these vines never seek to grow above and the middle tier of the forest is where you can findthem. They use tendrils to fasten themselves from one plant to the other and provide the photographer with a keen eye the opportunity to make beautiful backlit photos.


Ferns faste themselves to tree trunks and grow to the middle tier seeking for their share of light. Their beautiful green colors makes them a wonderful subject to photograph. 


At times one has to walk around to get a good background to make you composition. I favour shadowy areas, however if one applies shallow DOF and wonderful contrasting colors to bring you subject out, it will enhance your pictures as a whole.

IN SEARCH FOR MORE LIGHT

Creep up or spread out. These are two strategies that plants use to search for the spotlights. Phyllodendrums like this heart shapped climber circle around tree trunks on their way to the middle tier of the forest. They do this to optimize light gathering. 


Most climbers will flush greater numbers of leafs towards canopy gaps where light may filter through into the forest floor. Note how this plant is growing its leafs towards the opening in the canopy. By circling the tree trunk, any light that breaks through the canopy will encounter aleaf or a portion of one where
photosynthesis will take place.


Palms expand their leafs surfaces to increase the suface area exposed to the sun light. A tight crop along with a strong back light will be a great way to document this.


Dividing the leafs with alternating leaflets is a variation of the strategy used by palms that live in the understory of the cloud forest. Cropping tight may make more of an abstract representation on how palms grow, but the high contrast between the places where light penetrates and those in the shade allow, for an out of the bunch picture, of plant adaptations. 


WHEN THE SPOTLIGHT IS TOO MUCH

Understory plants have gone, through millions of years of evolution, a way to cope and thrive under adverse conditions of light, therefore, been under the spotlight too long can be harmful to them. The Calathea, in the picture bellow, curls up when there is too much light, and ulfolds, when the conditions become favorable again.


So there are pros and cons to the exposure to nature's spotlight. For most nature photographers, researching the influence of lighting conditions in the understory may be an over kill, however, learning the most about the subject one is about to photograph makes a big difference, as making photos with a deep meaning is a challenge thay pays in the long run.

 THE IMPORTANCE OF STANDING OUT

Plants in the understory blend in with their surroundings, however, when it comes to have reproductive success, they need to be UNDER THE SPOTLIGHT!
Heliconias, Calatheas, and Gingers need to attract polinators to their respective flowers. So they resort to visual cues to stand out for their animal partners. To do this, a lot of them are colored red,orange and yellow that are outstanding bright colors, when it comes to attracting diurnal pollinators. So it is very important for flowers and bracts to stand out and make themselves visible at great distances, as bird pollinators require visual cues to find their food sources.


The heliconia above and the Marantaceae bellow are good examples on how color and positioning the flowers under spotlights can benefit these understory plants pollinators.


I am sure that there are many other subjects that one could write about working with restrictive light conditions such as nature's spotlights. Furthermore, the spotlight subject can be transfered to the urban jungle where it will be a fascinating photography subject by its own right, however, I feel safer in the forest than in the urban jungle, and I am sure, that many of you out there, may feel the same way.

FOLLOWING THE SPOTLIGHT

What happens when one finds an object or a frame, where the spotlight moves  ,because of the wind sets in motion the branches of the canopy changing the position of the light, as it penetrates into the forest floor.


A good example is this patch of peace lilies, and it may seem as a difficult problem to solve, however, the great thing of having a digital camera is that one can see the results of our clicks in an instant. This allows us to correct exposures, composition and so on, which one could not do with film cameras.

The sequence of pictures above were taken during a different shoot. I did have my tripod and the cable realease then. So turning my mind on to the possibilities rendered by the use of the digital darkroom, I did the following things: Set the camera to manual, desided to use an exposure that favored the highlights, turned on the Live View on my camera, so I could focus presicely on each of my subjects. Then I made the desired composition. And using live view I focused on the foreground for the first picture, and then repeated the same technique for the middle ground and background respectively, in order to get as much detail as I could, from each area. By having the camera mounted on a tripod to keep the same framing throughout the series and I clicked away as best as I could, to make the best of the moving spotlight throughout the frame. Later, I stacked the pictures in Photoshop which rendered the composite that you see above.

So to conclude, play with the light as much as you can and don't underestimate the little things in nature because thay can become a huge learning experience for any photographer.

Happy clicks, and see you soon.

NATLEO : LA FOTOGRAFIA Y LOS SENTIMIENTOS



EL CONTACTO CREA EL VÍNCULO
Texto y fotos: Leopoldo García Berrizbeitia

Esta manifestación del Dr. Manuel Barroso, es tan imponente, que muy pocos estamos conscientes de su poderosa realidad. Mientras más lejos nos encontremos de los objetos de nuestros afectos, más se debilitan los vínculos que tenemos hacia ellos. Pero si nunca hacemos contacto con nada, pues a nada nos vincularemos. El vínculo se hace con la voluntad de hacer el contacto. Ya me queda claro, que es el desgano a maravillarse con aprender, que tiene la humanidad actual, la que la ha llevado al desapego entre lo afectivo, los valores y nuestro entorno. También desconocemos, que al hacer contacto a un entorno rico en estímulos e información, este nos ayuda a crecer en todas nuestras capasidades cognitivas y sensoriales. En consecuencia, tomar la acción de hacer un contacto de descubrimiento de nuestro entorno, con guías que estén afectivamente vinculados a nosotros, es potenciar las capacidades coginitivas y afectivas, que nos ayudarán a crear vínculos energizantes y generadores de individuos integrales, capaces, de encontrar disfrute de lo que le es, actualmente invisible, y que siempre ha estado a su alcance, EL AMOR Y LA RESPONSABILIDAD QUE VIENE DE ESTAR EN CONTACTO CON SU SER Y EL MUNDO.

Cuando un niño se maravilla con un colibrí desde los brazos confiables de su padre y la sonriza aparece sobre sus respectivos rostros, la muestra, de la importancia de  hacer contacto con algo que nos da placer, pero que tiene vida propia es incalculable. Solo así se generan los afectos por la libertad y el arraigo a la tierra a la que todos pertenecemos.

EL AÑO DEL COLIBRÍ / THE YEAR OF THE HUMMINGBIRD


ESPAÑOL

Hola a todos, uno de los mejores regalos de este año ha sido sus visitas a Digital Camera Adventures y el artículo favorito de todos está relacionado a unos pajaritos, que realizan acciones maravillosas a pesar de su tamaño... LOS COLIBRÍES. Este año va a ser EL AÑO DEL COLIBRÍ y les estaré haciendo entregas sobre su comportamiento, historia natural, como cuidarlos y fotografiarlos en estado libre.

Hoy les regalo una gema, la foto del Safiro de Cola de Oro macho, una de las gemas de la joyería más linda de Venezuela El Bosque Nublado de la Serranía del Interior. Adjunto a esta nota van los artículos en español e inglés para todos los que han hecho de DCA un lugar de consulta. Les agradezco compartan los artículos, para que otros tengan la misma oportunidad de aprender de estas bellas y diminutas aves, y nos ayuden a preservar para otros, a estas criaturas y el Bosque Nublado donde viven. Recuérdense que los bosques nublados, además de ser los más biodiversos, solo cubren el 10% de la tierra, pero de ellos nacen las fuentes de agua más importantes del mundo como: El Amazonas, Ganges y el Yangse para nombrar algunos.

ENGLISH

Hello everyone, one of the best gifts of this year has been your visits to Digital Camera Adventures, and the most read article in the blog is related, to a group of tiny birds that accomplish great feats THE HUMMINGBIRDS.

IPHONETOGRAPHY: CAMERA-PHONES AND THE PHOTOGRAPHERS

INTRODUCTION

Becoming an advocate for cameraphones is quite easy, as the only way for photographers to get better at their craft, is by making picturers. There is no way to master anything without work, and the way imaing and telecommunications technology are going, the merger between digital tablets, celphones and digital cameras, along with their respectivel applications, has reach a point that, all in one hybrids, will be common place in less than 5 years. Therefore, it makes perfect sense to own a cameraphone to take pictures and share them, as you go, with the rest of the world.


I've just recieved an IPhone 4S as a gift. At first, I was a bit threatened by this new devise as it has a great number of applications to make your life more organized, and it could make a well organized mess out of my work order. As it turns out, it syncronizes with Apple computers and places everything in a CLOUD, so both devices can work together and share files over the Internet. It could be god sent, but I was not prepared for this, and lo and behold, the Iphone and the MacBook did this on their own without me been concious about it. Furthermore, the learning curve of a cameraphone can be steep, as the apps recomended by friends and internet forums are mind boggling. And you have to be under 25 to make the best out of the cameraphone's full potetial ;-) Thus, I desided to do as most people do, be wise, and learn as we go.  

Now, just how important are cameraphones in digital photography, well, they are so important, that the compact camera sales went down 33% in 2011 and 36% in 2012 because of cameraphones. Why? because buyers drifted from compact cameras to cameraphones, as the latter,  get  their users a lot more for the money.

The presence of photo related internet sites like Picasa, Flickr, Facebook, G+, Instagram, and many others have added new objectives for picture taking. But just how much digital picture taking has changed the behaviour of digital camera users. Well, look at the stats: There are 6 billion photos uploaded to internet each day (Sourse: Google search). Facebook, which is not a photography site, has the following stats:  3,000 pictures are uploaded per second or 250 million per day. Then, they store the images in 4 sizes totalling 100,000,000 GB of image storage in a single day! Now, if cameraphones are the hotest idem in gadgetland they are responsible for part of this inmense volume of picture taking. So if one is to face the facts as they are,  I am sure, I better learn to use my cameraphone as well as I can.


Who is using cameraphones? I dare say, that most every one, and this will change photography as we know it. I have seen young children documenting their school outings with their cameraphones. Why, because they are documenting their field trip, so they can make their SHOW AND TELL project presentations on computers. So, by the time they reach college level education, cameraphones will be second nature for them, and the future devices will make the desktops and laptops things of the past.

FIELDWORKING WITH A CAMERAPHONE:

My self imposed IPhone challenge was to go to my work place, at Jardines Ecológicos Topotepuy Botanical Gardens and put the device to work. Sure, I took my 20 Lbs of camera gear as well, one would not want to loose a photo opportunity because of a camera phone! However, I could have left it home!!!

IPHONETOGRAPHIC SAFARI

Nature photograpy is very popular and working in natural surroundings places special demands on the photographer to get his job done. The proper care for the gear is very importan no matter what the conditions may be. So reducing risk is quite a relief and a small cameraphone is easy to deal with. Since internet demand images in low resolution, cameraphones can go a long way for publications like web pages, ezines, forums and blogs. They are limited as far as the things they can do, but they have enough capabilities to cover a great deal of subject matter successfully as this publication readily shows.


Therefore, if you are in a family outing, the pressure for impecable image quality is not as demanding as printed media. So carrying an 8MP cameraphone in my fannypack, did not face me as much, as my photo backpack did. The field test was in a cloud forest where one can expect fog, rain, or high humidity. Well, the Iphone was inside two plastic bags that kept it dry all day. So one may keep a cameraphone with you all the time, and unexpected events can be documented in an instant, and this is a clear advantage over bulky gear. 

A good example about spontaneous nature photography is the blooming of this Walking Iris. This plant is an explosive bloomer, as most of the plants have a peak in blooming at the same time. If you happen to be in the area when this happens, you will get the shots, however, if you do not have a camera with you all the time, you will be out of luck. The cameraphone can help in many ways, the obvious one, by taking the picture as he action occurs. But if you are following the growing season of a cloud forest or a garden, you could record the flower buds' maturity and prepare yourself for the event, so you can record it with a DSLR. The metadata of the photos will have valuable information on the subject and for a nature photographer, and his botanical garden client, having a blooming calendar of their plants can be very important.


How many of you have been told, wow, that camera really takes good pictures...
Well, in Venezuela we reply... its not the bow and arrows ITS THE INDIAN! If the cameraphone user has experience, the tool will enable him/her to accomplish great photos. I wanted to see how well the cameraphone worked to record the petal arrangement of the iris, well its DOF, was quite decent. The white petals, and the dark background were not right on the money, as white balance in a bright/shaded situation is hard to handle, however, to most people, the iris flower will be regarded as a beautiful image. For the nature photographer, it was great to have the picture to show in the blog, and a metadata that pinpointed the exact date of the iris blooming was great information for the park´s flowering plants calendar.


To be honest, I am very happy with the colors, depth of field and resolution of the pictures. Specially, when they came form a cameraphone costing a lot less than some mid-range digital single lens reflex camera gear.


As for the bromeliad series the Iphone worked equally well. The tonal range of the pictures and the color saturation are very pleasing.




At the time I was taking this pictures, I did not know that the Iphone camera could zoom in and out, so I did not make any extreme close ups. However, there are lenses from third party makers that can be adapted to do macro, wide angle and even fish eye photos.


I had never seen a bromeliad grow on top of another bromeliad, however here it was! now I will keep an eye on this occurrense and keep on documenting the issue over time.



The picture of a white object in the shade is a challenge for any photographer. Keeping the details of the background without blowing up the whites or working the whites without loosing details in the shadows is a toss up. As one cannot compensate brightness and shade with an automatic camera of any kind, I focused on the middle orchid and the cameraphone did the rest. The flowers retained their brightness and shadows with very little loss in the details. So I was happy with the outcome.


Getting close and working with perspective with the Iphone camera worked well.


Here the trick was placing the cameraphone horizontally with its left side of the screen close to the flower and the right side towards the fern. The result was very good as well.


MAKING AN 8MP CAMERA RENDER MULTIPLES OF 8MP PICTURES

The Iphone's camera has an 8 MP sensor and that prompted me to try a technique where one takes several images of the same object to make a panorama or a high resolution mosaic. To get the proper results, one has to set the camera in manual. The  exposure has to be the same for all the pictures you take, so when the stiching is done, there will not be extreme jumps between the light and shadows of the final photograph.


Well, cameraphones do not have manual mode YET, so, as you see from the pictures above, if your composition ranges from the extremes, you will not be able to make the mosaic. However, with practice, you can choose subjects that are in the same light range, and get away with a photo with a higher pixel count. I chose the last two of the strip, and you can see the result below.


In conclusion, I am very happy with my cameraphone and if you know its limitations and capabilities you will be as happy as anyone who own one of this devices. I love to hear from you and I need to have a greater number of followers so Google and my patrons keep on helping me with the productions, so please  subscribe to the blog and help me bring you more Digital Camera Adventures to the net.

If you want to learn how to do this, I prepared a Photoshop tutorial to show you how is done. 




TUTORIAL 

As I told you before, once you learn techniques with your DSLR, some of them can be used to help you with your cameraphone. One of them is stitching photos together to make a Panorama or a high resolution mosaic. The IPhone as many other camera phones have panorama capabilities pre-installed in them. However, if your cameraphone does not have this function, you can do it yourself.


The most important issue here is the fact, that cameraphones do not have a Manual Mode "M" YET. I am sure that, as I am writing this, somewhere out there, there is someone or a group of people working on an application that will do that and more. Or there are apps out there that do this already, and I do not know about. However, the DSLR knowhow is very helpful, as is, the knowledge on Photoshop to stitch several cameraphone pictures together. 

The strip of photos above are numbered 1 through 3. In photo number 1, the cameraphone meter was tricked into exposing for the bright sky and the EXIF data shows f/2.8 at 1/500th and ISO 50, thus rendering the canopy of the forest useless. In picture 2 the sensor reading was f/2.4 at 1/60th of a second at ISO   50 and in number 3 the reading was f/2.4 at 1/40th of a second at ISO 64. Pictures number 2 and 3 come very close and by using Camera Raw with your jpeg images in Photoshop, you can make them look even closer. Once you are finished and hav saved the pictures, you can use the TOOLS menu in Bridge to stitch them together.


First select the pictures you want to stitch together.


Go to the Tools menu and open the Photoshop Tools menu an select
Photomerge


Once you have selected Photomerge a window opens. On its left side you will find the layout choices, I often get the best results by selecting the Auto options for lanscape pictures stiching and cilindrical for portraid image stitching. Make sure you select Vignete Removal to avoid dark edges in your stiched photo.

Once that is done Photoshop will render an image as two layers
bonded together. Look at the lower right.


I use tha Flatten Layer option to make a single image, you can do this from the Layers drop down menu.


Once that is done, you can cropp the image as you desire.


Then, I resize for the Internet by going to the Image dropdown menu
and selecting Image Size


In this picture you will see that the new image's size is 30.4 MB!
With a pixel dimension that exeeds 3,000 in with and lenght. So one needs to downsize the image for Internet use. I place the resolution at 72 DPI and the longest side WIDTH/LENGTH between 1100 and 1500 for most of my pictures on internet. And now you are ready to save your panorama for future work.

Well, I hope you enjoyed this new cameraphone adventure. Make sure that you learn the photo apps available for your cameraphone, and just go out there and click away. 

See you soon
