Most of our studios have been what we referred to as as low light efficiency studios (flat black in the shooting areas; walls, ceilings and floors). Chosen because of the our style of lighting we most commonly used (most of our work was product and still life. This type of studio has some cons: 1) it requires more watt seconds of gear 2) flat black is more easily marked and requires more touchup, but the pros (for us) far outweighed them. We also did a lot of multiple exposure photography and the low reflectance managed most stray light.
We generally turned the shooting space into a high efficiency studio for most people shoots by covering the walls with white materials, (cloth, 8x10 sheets of foam core, etc).
We made up for the "depressing" black space and clothing with our extremely exhuberant attitudes, loud blues music and drugs (caffeine of course)....
