Bleach bypass is one of those processing strategies that seems to be loved by every generation of filmmakers, but I'm wondering what it can be used for beyond making the audience feel a character's sadness and/or fear?
What unexpected emotions can it be used to convey—what reaction can it evoke from the audience? How have you used it to create other moods? Would there be a humorous use of bleach bypass?
And finally, is it best used for the whole picture or is it more effective when used in just a few scenes?
