Hi,

Very easy if you have a camera that will run backwards (Cap the lens first!) Man on Fire 2004 used it with great effect.

Hi,

Ideally you need to test. For a normal scene underexpose about half a stop, the 2 exposures will be slightly overexposed and that is ok.
If you are shooting against black then your exposures should be normal.

Have fun and take some risks!

It was done in Citizen Kane in the scene with the glass in the foreground -- I'd be more specific but it's been a while since i've seen it. Any way it's done with a mask over the back ground, then a mask over the exposed section to get the whole frame in sharp focus. the edge of the matte will be soft depending on the iris setting and due to the close proximity to the film plane. How's that for creative.
