World Pinhole Camera Day

April 24th is World Pinhole Camera Day! This holiday always falls on the last Sunday of April.

Pinhole cameras are the simplest form of camera. All cameras are based on the principle of camera obscura. Here is an interesting demonstration...



A few weeks ago I attended a workshop at USU. They taught us how to make our own pinhole cameras and how to use them.

Here is a photo of the materials they gave us.



These cameras were made of black foam core, black cardboard, black duct tape, rubber bands, glue, a 2"x" piece of soda can with a pinhole drilled into it, black marker, and that film holder from a 4x5 camera. With the exception of the film holder, you should be able to find everything easily at the nearest craft store or your own home.

If you want measurements and instructions just leave a comment and I will happily email them to you.

Here is the finished camera



You can make a camera out of any light-tight box. To seal any light leaks use electrical tape or black duct. The reason why I LOVE this particular pinhole camera is the easy of loading and unloading the film. If you had multiple film backs you could load all your backs before going out and make as many exposures as you want without having to stop to load and unload the film in a dark room.

If you want to make this camera and you want to buy 4x5 film backs check ebay. You could buy 4x5 film...but it is much easier to cut film paper down to 4x5 pieces and load them into the film back and use them as the negatives.

Here is a photo of my paper negative taken with the pinhole camera and the contact print made from it.



If you don't have your own dark room for developing talk to any local colleges, trade schools, or high schools that have a photo program. Many will allow the general public to use the lab for a fee.

The most simple camera I ever made was out of an oatmeal box. You don't need to spend a lot of money or get fancy. Just a light tight box with a small aperature pierced in the front and a way to affix a negative inside the back, and a way to cover or expose the aperature.
