Green screen lighting

Hi everybody, hope somebody here can help me.

I'm trying to setup a mini green screen but i cant seem to get the lighting right cause my main subject either gets transparent or when i hit the green screen in the chroma key plug in the background changes to gray.

I have two 75 watt bulbs on top for my background and a 125 watt on the center for my subject. I've changed the places of the lights but nothing has worked.

Hope to hear from someone soon..

Cheers,Ü

What do you mean on top? The green screen should be lit separately from your subject. You may not have enough lights in general.

move your subject six feet away from the wall and try to light the wall evenly. Do you have a backlight on your subject? It will help bring your subject out of the background. Making the wall brighter lit than your subject may help too.

With the footage you have. Try dropping a secondary color corrector on the green screen and increase the green saturation. Now try your chroma key again.

Thanks very much Buster! (no pun intended)

What i mean is the bulbs are situated so that it lights down on the background. I do not know really how to position it.

When you mean backlight that means i got to have a light at the back of my subject right? How can i do that?

Here's basically my problem, i do not know where to situate my light sources. COuld you please give me a basic map on where the lights should be? On the sides? Front? Back?

Hope to hear from you...

Cheers!!

You need to use 5K flourescents, daylight bulbs, in several shop lights.

Here's a video lighting walkthrough of my home chromakey studio, it works great:
