Answer:

1.Digital photography uses cameras containing arrays of electronic photodetectors to produce images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing.

2.The advantages of digital cameras and photography include: The resolution of a point-and-shoot camera, which is often 12 to 20 megapixels, is a high enough resolution for large prints. A digital camera is usually lighter in weight than a film camera. Memory cards are tiny so they don't require much storage space.

3.A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.
