I have to shoot some interview scenes in a mini bus/limo. Any sugestions on lighting would be helpfull. I need a cheap but effective solution for the shoot.

Shooting daylight or night and is the bus moving or still? Is the background (scenery) important? How many in the shot max? Need reverse angles? Any shots from outside the van? Clothing and skin tone can also be factors....

The setup needs to be like the MTV show "Next" or "Elimidate". Various skin tones will be on camera at a time. (no more then 3). An LCD or plasma monitor will display a logo or subsequent footage behind the talent..

Assuming the windows will be tinted dark your job shouldn't be too difficult. If they are tinted with the usual grey tint, you will probably want to try matching your artificial light to daylight balanced color.

The one area where you might have difficulty could be with reflections on the windows. Whatever light you use may show up in a reflection. You can try to alway shoot at 45 degrees to the windows or shoot from high angles.
