So, I wanted a nice simple backdrop so future pics won't show the mess in the garage, and so light can be bounced back and kept on this studio side of the shop space. Cheap, simple, use whats on hand are my directives, so i cut a big slab of cardboard from a box going to the dump, taped up torn paper bag for a mask, and whipped out the trusty rattlecans. Brown for the foreground, metallic silver, aqua, purple, and pink, and lotsa white did for sky.
