The Digital Pinhole is just a digital camera with a pinhole instead of a lens! To make simply get a lens cap, drill a hole in it, get a pinhole and tape it on the inside. It takes photos just like an ordinary digital camera but instead of a lens it has a pinhole.
It is digital, so you can upload photos to your computer. All you need to do is click a button! No need to wind the film, as it has none! Hard to do accidental double exposures.
You need to hold the button and it usually wobbles. The quality of the photos isn`t as good as a film pinhole camera.
