There is another reason why I take so many photographs: In order to get the look that I am after, it often involves, like painting, using a raw or a burnt umber, a pathalo or an ultramarine blue, a veridian or a forest green.
The digital era, while short on lasting value, is long on experimental value. In the old days, we were limited to one roll of film at a time. Kodachrome for a warm look, Velvia for vivid, Extachrome for cool, etc. That was our white balance. To achieve a neutral white balance that properly exposed the whites, we would calibrate the meter on an 18% gray card. We would hold the 4x4 card in open shade and take a meter reading. This would give us a starting point to proper exposure. We wouldn't know if we got it right until the film was processed.
Now, on average, I will take nearly 200 shots daily when I am out. That amounts to roughly ten rolls of 24 exposure film daily. In the film days, I was lucky to shoot that much in a month.
And still, I do believe that I come under the 100,000 exposure mark that Thom Hogan says you need on a camera in order to consider yourself having mastered your craft. Even today, there I was, fiddling with the exposure and white balance and focus like trying to play a warped necked guitar out of tune.
It will be a glorious day when I go forth into the field and I am master of the camera, it melting in my hands, not my cursing mouth.
