Another way that photography serves me is as a form of meditation.
I am always relaxed and calm and I take slow deep breaths to avoid camera shake (sensation). I am laser-focused on only the task in front of me. It is a very intimate thing. When I look through the lens, what is there is all there is in the universe. Nothing else matters at that moment. I have chosen to frame the image in a certain way, and nothing exists beyond that frame. I've left things out, and I may have had to move my physical location to get the exact right composition from as little as an inch to a foot or even a completely different angle.
A crazy example:
I wanted to capture a certain hill in the desert with a large cactus in the foreground. I felt reverence for this hill’s unwavering presence and hoped to pass this emotion on to others. Words would simply not do. I backed up step by step until the image was in the frame the way I envisioned it in my mind (imagination). Several different exposures helped to make sure I had at least one good photo, i.e. quality of composition, focus, color, lighting, lead lines, shapes, etc, all coming together correctly to fulfill the purpose of the photo (thinking).
Then I stepped forward to collect my belongings, and, checking behind me, realized that one of my feet had been exactly on the edge of a 50-foot cliff. Talk about sensation ! Stomach in my throat! My professor's voice: "Do whatever it takes to get that picture -- hang from the chandelier if you have to." But hanging from a cliff is another matter. Having been completely absorbed in getting the image I was determined to capture (desire/impulse), I had forgotten to attend to my immediate surroundings. Had I moved back one step more, no one would ever have seen me again -- I was in an isolated area and no one knew where I had gone except "into the desert."
Photography taps into emotions on two levels: images are created by the feelings of the creator, and they evoke feelings in the viewer. This was the case one day at sunset on a lakeshore. Several people stood still as the sky evolved into one of the most spectacular sunsets we had ever seen. We looked at each other speechlessly, sensing the spiritual reverence of the moment. While staying in this mood, I impulsively took as many photos as I could -- sunsets only last around 10 minutes. When the magic began to fade, we returned to our normal day-to-day awareness levels, gathered our belongings and started leaving.
As I approached my car, a woman was just arriving. I commented to her that she had just missed a beyond-belief vision, and she regretted that she was too late. I showed her the photos in my camera's playback, and even from these tiny thumbnail images, she was able to experience some of the emotion the sunset had elicited in me.
