How To Make Pinhole Camera

How to make: 

Find a cylinder roughly the size and shape of a hot chocolate tin/tin of Smash. 

Paint the inside matte black, to ensure that there are no reflections. Paint the underside of the lid as well. Allow enough time to dry. You may need to paint more than one layer.

Cut a square into the tin three quarters of the way down.

Place a slide of thin metal (aluminum from a baking tray is advisable for ideal thickness to be pierced) on the inside of the tin where the hole is. It is also advised to wear down the surface of the piece of metal to reduce any chance of reflection.

Paint one side of metal strip matte black also.

Pierce a hole through the metal strip with a pin so that light can flood through into your pinhole camera.

Cover the metal strip with a strip of black tape, to keep the hole tight from letting in any unwanted light.

The black tape should be able to be pulled back with ease and be able to be stuck back over the hole to act as a shutter.

How to take:

Place a piece of white paper (glossy side facing the hole) in your 'camera'. Do this in complete darkness!
Close tin, assure that no light is entering tin.
Find what you want to take a photo of.
Place tin on a flat surface.
Pull the tape back for however seconds you feel is right. (An average time is roughly 15/20 seconds dependent on what effect you want to create and what light there is.)
Place the tape back over the hole.
Take into a dark room and develop.

You must assure that the only light entering the camera is that of when you are taking the photo. Otherwise you can ruin your photo and have to do it all over again.
