I was thinking of how old school has its own distinct style. I was finding for the reason why the style works in this way. This is the youtube video I found on.
I understand that Noises and Chromatic aberration because of hardware or software limitations.
The another thing I find is color palette. The old school palette has interestingly yellow tint or somewhat different color palette compared to modern style. I still can’t figured out why the color is behaving in this way.
