| Pinhole Photography: How does it Work? |
These pages will introduce you to the technical side of pinhole photography. Take a look at the images below
(with their help we will explain a few basics):

In "Image A" we have the object which we are taking a picture of (a tree). To the right we have our film-plane
(the negative which we are exposing). In between we have a Pinhole (basically a little hole punched into a
piece of cardboard, aluminum foil or metal plate of some sort). Obviously the film-plane and Pinhole need to be
contained in some kind of box in order to avoid the negative to be exposed by any light other than the light
traveling through the Pinhole.
In "Image B" we see that the tree is made of many different points reflecting light, through the Pinhole,
onto our negative (the image is, as with any camera, exposed upside down and side flipped). A lens functions
the same way, only that you can more specifically redirect the light emitted by the tree as well as shift the
focal-plane. The distance between the pinhole and the film-plane is the equivalent to a lens's focallength:
A 10mm distance equals a 10mm lens.
