Using the zone system for digital photography
I've just finished writing down my thoughts on adapting Ansel Adams' Zone System for digital photography and putting them up on my website.
After a lot of trial and (mostly) error, I found that the Zone System is just as useful with digital as it is with film. However, shooting digital is different from shooting film. This meant that some old rules of thumb (e.g. "expose for the shadows, develop for the highlights") had to be reformulated, and that some new rules of thumb (e.g. Micahel Reichmann's "expose (to the) right") is no substitute for using a spot meter.
