I think this is supposed to be the ocean, or a piece of wood? The inside of the camera? I can't remember but I love the color and texture.

My second try using 828 film in an old Kodak Bantam. The first roll was super expired from 1966 and came at a blur. This roll actual had a couple of images on it. I think I'll have to set the 828 film aside until I can figure out how to process it at home.
