In science we have pinhole cameras. We had some photographic paper which we put in our black pin hole camera box and stuck it to the back with blue tack. Then we put it on the step ladder and the other person would take the blue tack off the aperture (the hole in the camera) and we would have to stay still for 25 – 40 seconds then we would take it back to the dark room
When we developed the photographs we had to put it in the developing
Materials which were called developer fixer and the water. You had to put it in the developer for 2 minutes then we put it in the water for 10 seconds.
Then put it in the fixer for 2 minutes, then put it back in the water for 4 minutes then leave to dry.
What the chemicals do
The developer: the developer is the chemical that gets the image darker and shows the picture. The water: the water washes off all the excess developer before putting it in the fixer. The fixer: the fixer makes sure that when you take the paper out the image does not disappear.
