So I want to use a rather large and bare wall as a background. Naturally I want it to be white. I could just go and purchase white paint but it seems to me that the true "whiteness" of my studio wall would depend on the lighting conditions and the color cast of the lights illuminating it. How would I adjust for that when deciding what color to paint the wall? Is it just "the whiter the better"?
PS I didn't know which forum this question belonged in. There is a "Location and Travel" forum which is dedicated to locations outdoors, but not a "Studio Photography" forum?
