Making your own photography equipment might seem like a somewhat silly idea. After all, cameras are precision instruments composed of hundreds of carefully made and assembled parts. But depending on your photographic goals, you may very well be able to make a lot of the equipment you need, possibly even the camera itself.
Unless you're a skilled craftsperson, your DIY photo equipment might not look as slick or high-tech as commercially available items, but when you just need the stuff to work, who cares what it looks like? Most photography equipment is based on simple principles: capturing light on a sensitive surface; directing, filtering and reflecting light; and so on. Many of those principles can be replicated with home-built devices, allowing you to try out all sorts of fun techniques without having to spend a lot of cash.
