Well white it is. White top to bottom, side to side, all except the black floor.
So much for plan “A”, but happy enough to go with it. It’s only paint.
After painting my one intended white wall, my wife suggested I keep going with it.
The reality is, the tiny 8x10’ studio room looks bigger, brighter and cleaner this way and being small, I can control the brilliance with only a little effort (I hope).
For the longer right side wall I have a 12’ wide black backdrop.
For the left, I can use any of several 5-in-1’s ranging from 60 to 200cm wide or hand blankets etc as needed.
Another very cool thing is there is room for a book case just for photo books.
