How Did The Camera Used To Work?
Film cameras used to focus light on a light sensitive surface called film which was then put in a solution called developer that caused the image to appear. If the picture was to be printed the image on the film was negative, meaning the dark areas were light and the light areas dark. If it was to be projected onto a screen the images were positive -- like they appear to your eye. Digital cameras focus the light on light sensitive electronic sensors, then the computer in the camera interprets the information from these sensors and converts it into colors. Otherwise film cameras and digital cameras work about the same way.
