- What is “100% crop?” 4 answers
I've been reading a camera review which shows a picture with a tiny rectangle highlighted. It then shows that rectangle expanded to the same size as the original picture so that one can see the detail. This is referred to as a 100% crop in the review but that does not agree with the definitions given here. So what is it? I would call it a sectional enlargement!
