George Eastman stated:
Light makes photography. Embrace light. Admire it. Love it. But above all, know light. Know it for all you are worth, and you will know the key to photography.
On the other hand, Brooks Jensen wrote:
There is no such thing as "good" or "bad" light. There is just light.
While there are a number of ways to understand / interpret these two statements, it does seem that they represent opposing points of view, re: light. Whereas Eastman's notion is nearly fetishistic, Jensen's is rather dismissive, as in, what's all the fuss about? In either case, we should be able to agree on the fact that we all need light to make pictures.
In my case, I do have a specific type of light that I like-I embraced it, I admired it and I loved it-and, truth be told, light that I have "chased" - the light encountered during the time of day that is called entre chien et loup or, alternately, the gloamimg. That is, a time of day during which the sun has set but it is not yet full-on dark.
However, those "chasing the light" days are far behind me now. While I still make entre chien et loup pictures, I do so when that light "finds" me rather than "chasing" it all about the landscape .... and that M.O., re: light for picture making, is S.O.P. for my picture making....
.... which kinds places me in the there is just light picture making camp. That is, while at times the light itself pricks my eye and sensibilities, in which case I make pictures of the light itself (see today's pictures). But most times, I just work with whatever light I encounter.
In the case of strong directional light which creates tonal shapes and patterns, aka: chiaroscuro, I use those shapes and patterns as elements of my composition. Flat or soft light allows me to concentrate on just the arrangement of the visual elements of my composition, independent of the light as a composition element.
In either case, I don't see the light as "good" or "bad". I just see it asit is, aka: just light.
