The pinhole camera is an age old technique which was used in the very beginning of photography. It consists of a box with absolute no access to light in the box but of a pin small hole on one of the sides and a piece of photo sensitive paper on the other. The hole should stay covered until a scene is chosen to be photographed. When this is found, the hole should be exposed for the image to be imprinted on the paper. The amount of time you should leave it to expose depends on the weather or how well lit it is. It will need trial and error to find the best way to photograph the scene as seen below.
During our lesson we were asked to do a pinhole ourselves. It is very simple, you start wit a box and black it out completely on the inside. you cut a small square where you want your pin to be and then cover it with foil. With a small pin you puncture a whole in the foil. Now the whole in the foil needs to be covered, so we made a sort of cover like a door hat can be opened and closed. To take the image you place the paper inside while in the darkroom and close the box to make sure no light is going in.
We started with exposing for 15 minutes and experimenting with the time to find the best amount of time needed. To process the image one would need to take it to the darkroom and develop it the same way you develop a photogram. It is put in the developer for a minute and a half, moved to stop for 30 seconds, in the fix for 4 minutes and lastly washed in water and hung up to dry. As it is shown some of the images, they were left out too long and are overexposed. If I remember correctly they were left out for around 20 to 30 minutes as it was a very cloudy day.
