I just purchased a 50d a few months ago and now thinking of building a simple portrait setup in my basement. (2 daughters to take pics of) My basement has 9' ceilings and are unfinished. I will actually be using a section under a morning room above which will be aprox. 15' x 20' x 9' Money is not really an issue but I have a few questions...Should I leave the walls the poured cement gray color or paint then darker? Ceiling? As for lighting, I am finding all sorts of different setup's online but not sure what i should start off with.. Thanks for any direction.
