Here's a pic from Phil's photo shoot.
I'm harking back to when I had a studio like that with all the edges rounded off to create oblivion. Doing it on the cheap, for the corners we took a mould from half of a giant beach ball. If the studio was white, you could bet the next job would require black walls and floor. So out would come the black paint and the rollers on long poles. It used to get repainted weekly on average.
Here's a studio shot of Roger's 7 at Orange Lane.
