The Creative Workflow (WYSIWYG)

I am constantly on the lookout for new images. Even while I’m driving, one eye is searching for a photograph. But, to really see, it is important that I be present so I can delve into the potential image, dissect it and study the relationships between the elements. What is the best way to do this? What should I look for as I move through this process?

The first step is to ask myself: What was it that drew me to this scene? Usually it was a singular object, or a play of light over the landscape. The Soaptree Yuccas, the sidelit patterns, and the subtle light on the sand dunes at White Sands National Monument were what grabbed my attention and led to this first image. Understanding my motivation made it easier realize what I want to say with the photograph.

Next I had to frame the scene  in a way that would tell the story in the best way possible. I placed the closest yucca up front, but a little off center, leaving little doubt that it was the main subject of the image. This placement also allowed me to separate it from the others in the middle ground and avoid a confusing and static composition. My choices for the exposure had to be based on the dynamic range of the scene, which, In this case, was pretty wide considering the bright highlights on the sand in the distance, and the dark tonality in the shadows near sunset.

The first technical requirement was that I capture a broad dynamic range, so I made a bracketed series of exposures that covered the entire spectrum of tonalities in the scene. Even though I didn’t need to use all the different exposures, it’s better to have them and not need them than it is to need them and…well you know.  The next requirement was that the depth of field be wide enough to have sharp details front to rear. Because of the low light level at the time of day I was shooting this, the fact that I was shooting at the lowest possible ISO–to achieve the best possible image quality, and the small aperture needed to get the depth of field I required, my shutter speed was relatively slow–1/10th of a second. That meant that I needed to shoot with my camera mounted on a tripod (something I usually do anyway). It’s easy to see from this cause and effect chain how my creative workflow was based not only on composition and design elements, but also included technical considerations.

The second image of Sandhill Cranes at Bosque del Apache National Wildlife Refuge was made at twilight, that special time in the evening just after the sun set and the light is bouncing off the upper atmosphere. I was taken by the reflection of the colored sky and the reeds in the placid water of the foreground, and the transition from the smooth to the to the rough texture of the water, which created a layer-like effect because of the sudden change in color and texture. This layer is also where the action takes place: the cranes mingling, spreading their wings, foraging for dinner. There is then an abrupt transition to the golden reeds and the darker background before the final shift to the lighter tonality and magenta shades of the distant mountains and the sky.

I had my camera mounted on my tripod as usual, but I kept the bullhead swivel loose so I could easily pan to follow the movement of the birds. This image also relies on a wide depth of field to preserve sharpness in the details of all the layers mentioned above. I wanted to make the layering effect more obvious, so I boosted the saturation and contrast a little. Once again, the thought process kicks in and the decisions are made.  The point of all this is to stress the importance of being involved in the making of an image. If you want a photograph to be yours, you need to put a little of yourself into it, and you need to be intentional throughout the process.

Two Birds

I killed two birds with one stone the other evening: I did some “blue hour” photography, and I made some panorama images. I have been wanting, for some time now, to get out and photograph the “blue hour”. For those of you who are unfamiliar with the term, it refers to the hour before sun-up or after sundown when the light from the setting sun is reflected in the upper atmosphere. The more common name for this time is twilight, and it is divided into three distinct phases: civil, nautical, and astronomical. The duration of twilight changes depending on the time of year, and the latitude from which it is being observed. The blue reference has to do with the color of the light which has a wonderful bluish cast to it and is diffuse without any harsh shadows. So, I finally made myself go out into the diminishing day and drive to the Rio Puerco Valley. The prospect was sweetened by the full moon which would be rising about half an hour after sunset.

I arrived at my destination two hours before moonrise and set about scouting the area for a good location to photograph the event. Since I am quite familiar with the place, it didn’t take me very long to find what I was looking for. I set up my camera on a tripod and began making test images to determine the correct exposure. As the sun went down and the light softened, I began taking several series of vertical photographs which would later be stitched together in Photoshop to create the final panorama.  The first image was made about thirty minutes after sunset and about twenty minutes before moonrise.

The second photograph was actually made earlier than the first, but it was more of a test to get the feel for shooting the panorama and I didn’t expect to take it any further. After all, it’s full of cattle, which I consider to be a blight on the landscape. But, in the spirit of expanding my horizons (thank you Robin), I processed the image and, as it turned out, I liked it.

From the information I had gathered from The Photographer’s Ephemeris, I expected the full moon to rise somewhere between Cabezon Peak (the volcanic plug in the distance) and Cerro Cuate (the more prominent double peaked mount). But as the horizon began to brighten I was somewhat dismayed to discover that the moon was not where it was supposed to be…well at least not where I expected it to be. I checked the app on my iPhone again and saw that my expectations were based on a location that was actually a couple miles east of where I was.

I had planned to include the moon with the two mountains in the composition; that wasn’t possible from the place where I was standing. Now I had to re-think my plans, knowing that my window of opportunity was small if I was going to capture the moon close to the horizon. I quickly packed everything into my car and drove to the new location, walked to a place which afforded a clear view of the scene, set up, and composed the last image. By now it was dark, I was shooting thirty second exposures, and I was having to focus manually–auto focus doesn’t work very well in the dark. This being my first attempt at photographing at this time of day, and making panoramas, I wasn’t really very hopeful about the outcome. As full dark descended, I pack up my gear by the light of my headlamp and headed home.

The next morning I set about uploading and processing my previous night’s work. Each panorama is composed of nine vertical images which are then stitched together in Photoshop. As the first panorama was rendered I knew I was hooked. Somehow, despite the comedy of errors I had experienced while making the images, I managed to walk away with some finished photographs that I was happy with. It’s always an exhilarating feeling to discover a new technique and this was no exception. I made a few mistakes; there are some things I will do differently in the future, but overall, I’m happy with the way things turned out. It was a good night’s work.
