Pin Hole Cameras

The concept of a pin hole camera looks relatively simple.

I've done a little research (picture left is from wikipedia) and in addition to what Mr. Davies said the simplest designs are the best. Its just important that pin hole cameras don't allow any light in.

I will simply use a piece of black card to make two boxes bids of the same size. I'll then put a hole in once of the faces and mount paper to the inside of the opposite lid. So whats pictured is the same as what's shown in the picture above.

I predict that the difficultly will be in mastering the exposure time. I also suspect that we will have to expose the paper for a fair amount of time.. 10 secs or so... I assume to stop blurring the objects in shot must be still.
