The essay What slide film taught me (Archived at the Wayback machine) from Luminous Landscape relate what I basically feel about film photography, what happened with digital:
With digital, I have become sloppy. I can fix it in post processing — whether it is exposure (thanks to “RAW headroom”) or framing — crop with a few of clicks of the mouse. This has undoubtedly led to a lower quality of photographs.
I bought last year a Mamiya C-220 and rediscovered shooting film. Not that I got rid of the film gear I was using before, just that a TLR on medium format led me this new experience. I have been very happy with the result and the yield. I shoot mostly color negative with it, and this, with the scanning, offer some of the head room that slide do not offer. Still, thinking the shot makes my photography better.
