What is digital photography? Digital photography is the modern method of taking photographs. Traditional photography involves the use of film to record images.
Light reflected off the subject being photographed enters into the camera lens and exposes film in the camera. The film is very light sensitive and is composed of silver halides in gelatin on a plastic base for black-and-white films and dyes in gelatin on a plastic base for color films. The photographed images appear only after the film is chemically processed. The processed films are then projected onto light sensitive photographic paper and then the paper is developed in order to turn the negatives into positives. Slide film produces positives directly on the film and no printing is necessary. However, projection is required for the best viewing of the images.
Now, to answer the what is digital photography question, one must focus on how the image is recorded in the digital camera. Instead of film recording the image, sensors in the camera detect the light reflected back from the subject and convert it into many electrical signals. To be brief, the signals are then digitally coded and the codes for the image are stored usually on a flash memory device.
Because digital photography is different than traditional photography many people need help to learn digital photography and understand what is digital photography. Even those with more experience with digital photography may need extra help to produce high quality images with their digital cameras.
