I know they both produce pictures. I also know that they both have to store pictures until they are developed. Can you elaborate on these or do you have anymore ideas? Only that they can take and store images until you are ready to print them.
"Disposable" cameras do not auto-focus, have no adjustments that are operator adjustable, use cheap lenses, well the list goes on and on.
Buy a nice inexpensive compact digital camera and be done with it.
http://www.dpreview.com Both digital and disposables have a lens system, a sensor or film of some kind, and are essentially portable boxes for capturing an image.
From there, they begin to differ.
Disposable cameras are actually re-usable; once the film is taken out, the cameras can be reloaded with film and sold again. Most people think they get thrown away, but that's not the case. Elaborate on what? Digital cameras do not have to be "developed" and you get to keep them once you download the pictures. |
