This is actually a little blog about steel wool photography. A steel wool is a small, bullet-shaped bottle used in photography. It’s designed to hold a little shot glass, right? And it’s one of the oldest uses of this kind of camera around. But if you take a closer look, you’ll see that its original purpose was to be used to save on an article of clothing. Steel wool photography is actually a very old-school type of photography and the first step in using a new technology was getting into metal.
