Lighting Interview Style w/Chromakey

I know there have been discussions on lighting, but I have a specific situation I would like your input on. My company wants to start creating training videos in which we will video 1 person in front of a green screen. Would you suggest 3 point lighting to light the presenter and a separate light to light the green screen? Is there a kit from Lowel or other company that would take care of my needs?

Thanks for any help.

Not neccisarily. Check out this site on their green screen technique:
Digital Juice

they also have other great tips on video & audio editing.

Try to give enough space between the subject and the screen. 6 feet should be safe.

Try to have the green screen evenly lit. Look for and try to eliminate hotspots/dark spots on the greenscreen. If you look at the Digital Juice page, notice that the hotspots are right near the light. Their big screen allows them to frame the hotspots out of the shot.

You definitely want a backlight on your subject to give depth and bring your subject out of the background. Some people use a pink or blue gel on the backlight, because the pink/blue light would be easier to distinguish from the green of screen.

Search this board for greenscreen or chromakey and you will find a lot of tips. There are other step by step tutorials on the web as well.

Treat the subject as a separate entity. Use gels on the subject
if needed to match the background environment. If your background
is near a sunset....use warmer colors.

I have found the plastic silver light diffusers "##" shaped holes used in
overhead flourescent lighting helps reduce the hotspots on the screen.

I'm doing well. Thanks for your concern. I was at NAB last week.
