Hello everyone,
I'm shooting a scene involving a character who's been locked in what would visually equate to an underground prison cell for many years and my intention is to create a very dark and gritty look. So, I've been exploring different ways to do that in camera as well as through lighting and I am wondering if anybody has experience applying a 'dusty' look to a clear optical flat filter? Is there some kind of spray I can buy and apply to it without causing any damage to the filter?
I'd like the scene to appear almost as though we're seeing it through a dirty window pane with a texture similar to the photo below.
