I'm working as a gaffer for a student film this January. The story is a drama/thriller that follows a man who dies and becomes trapped in a sort of limbo state of being. It's dark. It's fantasy. Our budget is very modest, but I'm very interested in using half hampshire on the windows for all day interior scenes - I love the blur it gives. However, those scenes make up only 30% of the film and the rest is night interiors. I'm wondering, can hampshire be used on windows at night to any great effect?
I've looked into using dirty water and a spray bottle, but I imagine it will lack what the hampshire will deliver. Any advice is appreciated.
