So like I have stated before, I am currently in film school. I am shooting a film about a homeless man who goes into and out of vivid hallucinations of a different life. I am trying to figure out a way, in camera, to convey to the audience when he is leaving reality. I was told about the clairmont Squishy lens. However, I dont have the money to rent one. We will be shooting on a Arri SR2. Is there anyother cheap way to pull off some kind of cool visual affect similar to the Squishy lens?
