Topic: Fog / Rays of Light In-Camera
I came across a Flickr photostream a while back in which a guy photographs LEGO underwater, with some milk mixed into the water, to create dramatic lighting effects:
The look of these photos is pretty spectacular, so I'm intrigued by the idea of attempting something similar in a brickfilm. However I am concerned that filming stop motion underwater might be nearly impossible; the main thing I think you'd run into is that the pattern of the rays of light would fluctuate somewhat from frame to frame due to the inconsistency in the water's surface.
That said I haven't tried it so perhaps it may work better than I'm guessing. However, I wonder if using some kind of dry smoke/fog solution might be better. I don't know much about this stuff; here's a thread offering various solutions for smoke effects, though in the context of filling a whole room with it. What with the camera equipment, LEGO, etc. I'd be reluctant to use something that might leave residue or cause damage. I've never used any of this stuff before so I don't know what would work best. Dry ice is the cleanest, so that seems promising to me, but I don't know how difficult it might be to control or get to be sufficiently thin and consistent.
Thoughts?
