Macro & Close-up Photography using a Reversed Lens
If you use an interchangeable lens camera, you can purchase an adapter that will let you reverse mount a lens on the camera. Depending on the focal length of the lens, this can get you a good macro photo. A lens with a focal length of 50mm will give a reproduction ratio of around 1:1 when reverse mounted.
