Back in the day when I was a commercial photographer burning through 120, with two assistants to load backs and no financial or logistical limit to the amount I could shoot, I didn't shoot really much more or less than I did later with digital. I might have shot a tad more with digital simply because film is so much more trustworthy with exposure, but that would be about it. I hate overshooting. It's just simply more work for the same result, or worse, a dilution of effort and subsequent sub par performance resultant from overshooting whilst under thinking. It was always the young guys who wanted 900 half baked shots. I usually got around to firing them.
