    Hey guys. I do a bit of chroma keying with a greenscreen and I was wondering what kind of lighting I should use, keeping in mind that I have a relatively small area and I cuurently just use a 500 watt floodlight. It works, but the results aren't great. Any advice?

    I came across this video a while ago and have been meaning to set something up like it once I move out and get a place with a garage. But for the most part seems like a pretty inexpensive set up using clamp shop lights mounted on a PVC structure.

    First you should light the green screen and after that you light the object, that will be keyed out later.
    A proper distance between object and green is of importance (3-5 m), because of green spill from the screen on the object, and spill from the light lighting the object onto the screen.

    I used some kind of Vectorscope software for Mac OS X connected to a Firewire camera.
    Monitor Magic
    VideoScope

    Via this software I could at least technically check, if the lighting is right, as an accurate lighting results in an almost flat line from the left to the right in the vectorscope.

    You should also look at some guides via Google (or any other search engine): how to light a blue screen / green screen .

    thats not enough

    excuse me for asking but how much of a budget do you have, cause it will make a difference of what lights to buy.

    I know that's not enough, that's why I'm asking for advice lol.

    Anyway. Thanks for everyone's advice, I'll definitely check those sites out.

    Keep in mind that I have a pretty low budget, but I would probably be willing to invest in a lighting rig, since I let my friends use my "studio" and they have stated that they would happily help me invest in such a thing.

    To be honest, my biggest problem lies in that I have very limited space. About 3-5 metres throw distance from the camera.
