Many people post on here saying something about black-crush or white-blow-out, but don’t explain the context of why that is bad in the context they are talking about. However, I would think, black-crush and white-blow-out are not inherently bad and mostly dependent on direction and production.

Perhaps why thinking of what black-crush and white-blow-out is wrong and my interpretations are below.

Black Crush - when 2 pictures of the same scene have some dark (or shadow) details replaced with black

White Blow Ou - the opposite of black crush, when 2 pictures of the same scene have details replaced with white.

For anyone who got this far, I bring this up because I see lots of posts here and else where saying this version is bad because of black-crush or white-blow-outs, and that makes no sense.
