Thanks for looking...
I need to film a scene with a blacked out background (I have black stage curtains or black colourama paper from a photo studio for the background) but with a central, sometimes swinging lightbulb, at about head height or slightly above. The lightbulb is rigged to a dimmer switch so i can vary the output and there will be one and two people in the shot.
I want it to look as though the lightbulb is the only source of light, so that at times the light moves with the swing of the bulb.
Shooting on an HD canon - can't remember the model right now - the one without the inter-changeable lenses and maybe a Z1 but I think I'd rather just use the canon. Also have a set of pretty good lights (3).
Any and all tips on how to achieve this would be massively appreciated - assume that I don't really know what i'm doing and have a budget of favors, snacks and pennies.
