LIGHT. THERE ARE TIMES WHEN A PICTURE CAN BE "about" light. After all, George Eastman said:
"Light makes photography. ... But above all, know light. Know it for all you are worth, and you will know the key to photography."
Without some form of light, making pictures is impossible, or, very difficult at best. However, to my eye and sensibilities, a picture which is all about light, that is, without a referent that adds rhythm and ryhme, is picture without compelling interest.
That written, I am a firm believer in the idea put forth by Brooks Jensen:
"There is no such thing as “good” or “bad” photographic light. There is just light."
Consequently, I am not a devotee of the concept of chasing the light. As long as there is some form of light that allows me to make a picture of what pricks my eye and sensibilities, that's fine by me. However, that written, there are times when light compliments-that is, it adds to the rhythm and rhyme-the structure of my picture because it is an integal part of what pricked my eye and sensibilities, that is fine by me as well.
