I have several scenes to shoot in which a young woman is descending a staircase while sleepwalking, and there is a lot of ambiguity in whether or not it is "a dream". I'm trying to select 4 x 4 filters to provide a "dreamy" look - without going overkill. I would specifically like something that keeps a stable, sharp image overall, but "scatters" the highlights or "rounds things off" into a haze or burred rim of light. I've heard lots of good things (and viewed examples) of Pro Mist and Black Frost filters but I cannot figure out if these are only noticable on 35mm film stock.
Since I am shooting on 16mm, I am wondering if the effects of these filters are going to be as perceptible as they would on a standard 35mm format, or how you would "transpose" their use from 35mm to 16mm? For example, would a 1/4 Pro Mist need to be bumped to a 1/2 on 16mm? Is the idea similar to the transposition of a 50mm lens on 35mm system to a 25mm on a 16mm system?
