• Images are captured on a roll of film in traditional photography. The film is made of plastic and contains layers of halide crystals that darken when exposed to light. These are referred to as negatives. Photographers can remove a roll of film from the camera once it is finished. The images from these negatives are then developed in a dark room using liquid chemicals.
• Although digital photography appears to have a similar mechanism, it captures photos using an electric sensor. Photographs are kept on a digital memory card rather than film. The resolution of these photos is measured in megapixels.
• Traditional photography is less convenient than digital photography, which is why it is so popular. Most digital cameras have a viewfinder that allows you to preview photographs as they are being captured.
