110+ years ago, Clarence H White was shooting as much as he could afford; one plate a week, and the results took him far. He was a named member of the photo secession and taught a who's who of modern photography.

No we don't experiment enough. We should experiment as much as we can afford. Money and darkroom time is the constraint with film, computer time and storage is the constraint with digital.

Sometimes I go shoot a roll of 120 and have 6 photos I'm really pleased with. Other times, I go shoot a couple rolls or a half dozen 4x5's and not be pleased. Light, inspiration, and skill all have to collide at once.
