Since arithmetic ain't by best subject, I have a lot of problems grasping the Zone System. But I've read that--in a nutshell--the Zone System is about (in simplest terms) exposing for the shadows and processing for the highlights.
the problem in digital is this: digital doesn't do a very good job with the highlights. if the highlights are too hot, there's no detail--they're simply blown out. In the shadow areas digital does a better job capturing detail and that detail can be enhanced with (software) processing, although noise and lousy contrast is sometimes the result. but not so for the highlights,: they're easily blown and once blown there's no detail in them to process.
so, does this mean the Zone System cannot be applied when shooting digital?
