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 Out -> 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.

You are correct, there is nothing inherently wrong with this and this is frequently used in the production of many films. The problem arises when new releases of old films have had their contrast and color timing screwed with. This is a preservation forum, and people want their disks to look somewhat close to how they looked in theaters.
