Harry Callahan had a talent for capturing mood. He was
disciplined, going out each morning to snap some photos,
spending the afternoon editing and developing (sounds like
writing). "To be a photographer," he says, "one must
photograph. No amount of book learning, no checklist of
seminars attended, can substitute for the simple act of
making pictures. Experience is the best teacher of all. And
for that, there are no guarantees that one will become an artist.
Only the journey matters." This advice applies to writers too.
Interestingly, Callahan was known for his hatred of storytelling
through photography. I think stories shone through despite
him, however. He captured moments, moments any writer
would imagine or spy and know to include in the prose.
