Below are the original photos I took with my pringles tin. They are all taken of areas in and around suffolk new college. They are in the order.
In this post I will be explaining how the image your pinhole is pointed at ends up as a photo or a piece of white photographic paper...
Taking your photo.
When you point your camera at your desired image and remove you cover the light from the image enters through the pinhole and goes is relayed onto the photographic paper. As the light can only travel in a straight line, light coming from below will hit the top of the paper and left will hit the right and so forth. This is why your image will eventually come out inverted.
The photographic paper has a coating of chemicals mixed up in a gelatin layer. A mixture called 'Silver Halide', chloride, silver, bromide and iodide. Different concentrations of other elements can effect how sensitive the paper is. When light comes into contact with the silver halide crystals the surface changes. Depending on the amount of light that hits it will decide the shade when it is developed, which creates the image. The chemical bath it is in stops the photos developing instantly, otherwise the entire paper would just turn black.
After this process is complete then you can develop your photo.
