Photo Booth on the Cheap
GOALS:
Curtains: Neutral color, a very light gray or cream.
Lighting: Halo of Hi intensity wide spectrum fluorescent
Flooring: Neutral paint with spots or coarse finish to hide water/oil drops and scuffs
WHAT I DID:
Curtains:
Real curtains are EXPENSIVE. I went with giant tarps from Tarps - Poly Tarps, Canvas Tarps - Tarps Plus. I chose cream colored (off-white). Not perfect, but it achieves all my goals.
Lighting:
I dont have the funds to light with softboxes, AND I hate single bulbs overhead because they reflect bright pin-point spots all over the paint. fluorescents arranged in a halo around the perimeter of the curtains (away from the top of the car) will help minimize the fluorescent stripes on the vehicle paint.
The most difficult part of lighting is the interior shots. Shadows are your enemy. Think BRIGHT and DIFFUSED light (light that bounces all over). I am weak in this area. Notice (in the pic below) how the image is fuzzy, this comes from the camera lens being open too long to grab enough light to produce the shot. I should have a 2nd lighting system just for interiors.
Flooring:
I went with a darker gray epoxy garage floor paint (with the specs of paint kit) found at Home Depot. The idea was to use a darker neutral paint to help the eye stay on the vehicle, not on the surroundings. I tried to rough up the floor (visually) with spots (or use a coarse finish) to hide water/oil drops and scuffs.
FLOORING LESSON!
Cars are heavy and photo booths get a LOT of traffic and you park the car in the same spot all the time!! If you turn the wheel while the car is NOT moving will eventually tear the paint off the concrete (if you do a shit application job like I did 
Do the job right or hire a pro to do it. We were forced to toss a vynil cover over it to hide the "paint holes"
