Did you know that The Lost World: Jurassic Park almost had a Bleach Bypass?
This is a technique where, during the processing of colour film, the bleaching step is skipped, leaving silver in the stock. This silver then creates an almost black-and-white layer, resulting in higher contrast, less saturation, and more pronounced grain.
Ultimately, cinematographer Janusz Kaminski abandoned this method as he didn't want to scare the audience too much.
I had originally linked the source, but it blocked the post lol
