A polaroid camera is a miniature darkroom
Photos taken by a polaroid camera are developed instantly thanks to a compact system which carries out all the analogue photo development processes inside the camera.
SHUTTER ALLOWS LIGHT INTO THE CAMERA 1
As you press the release button, light enters through the lens and is reflected onto the film.
LIGHT CREATES NEGATIVE 2
The light activates a blue, green, and red, light-sensitive film layer, releasing substances, that produce a negative.
ROLLS RELEASE DEVELOPING SOLUTION 3
When the negative has been produced, the camera spits out the film. Two rolling mechanisms crush capsules of developing paste at the bottom of the film frame. The material is distributed, activating substances in three other colour layers, colouring the photo.
