Effects of lighting on your materials
editReciprocity: light effects are cumulative in a simple additive manner. Even if you are using a flash, if you wanted to damage your material you'll need approximately 3600 flashes per day.
The light used in flatbed scanners doesn't affect your materials as well. See Light Levels Used in Modern Flatbed Scanners, by Timothy Vitale.

editFor shooting studio, you should use Matte black.
For editing, you need
- No glare from lights or windows, no bright or reflective things.
- All lighting should be D50 (5000 Kelving).
- Painting should match the N8 Gray Munsell. Since this painting might not be easy to get in your country, it is possible to make the formula yourself if you take the numbers to your painting store, using a pastel-tint white as a base.
