### Instruction: What is a digital camera?
### Response: A digital camera is a hand held device that captures images with a push of a button.  These images are usually stored on a memory disk or card which can be downloaded to a computer at a later time.  Digital cameras were also part of a revolution that replaced photographic film.  Digital cameras use flashes when no natural light is available.  They produce better picture quality than traditional photographic film cameras and there is no cost to develop pictures and print them in order to enjoy them.
