Pinhole Cameras & How They Work

The pinhole camera is the simplest camera you can get. It consists of a lightproof box, some film, and a pinhole. 

They are also known as the camera obscura, which means ‘dark chamber’. And that’s what they originally were, a dark chamber with a hole in it. But how do they work?

Pinhole cameras are quite similar to the eye. The light goes in the tiny hole on the front at different strengths. It then reflects onto the film and the film then catches it. The light is closed off and the box becomes dark once more. The film is then taken out and processed.

Pinhole cameras have advantages and disadvantages.


The advantages of pinhole cameras are their depth of focus. Everything in an image taken by a pinhole camera are in focus, it has an infinite depth. Another good thing about the pinhole camera is that it is really simple, to make and to use.


Even though pinhole cameras are great and simple, that does come with disadvantages. For example the pinhole camera has longer exposure times than a regular camera. This also means that you have to have a tripod or something like a tripod to keep it stable. Another disadvantage is the clarity of the photos. Because it doesn't have a lens, the photos aren't as sharp. They also aren't very good for taking moving or action photos.
