What size print can you make with an 8 MP camera?

Answer 1

The size of a print from a digital image depends on a number of factors, some of which are the exposure of the image (especially the ISO rating), the quality setting of the camera for the image file size, the kind of camera software (especially for noise reduction), the size of the camera sensor, quality of the printer, ink and paper, and so forth. The desired end quality is also an issue. For an image to be viewed at 8 feet, you can get away with more than one that will be viewed in someone's hand. You may have noted that I did not mention the quality of the camera or lens. These are minor factors, as long as the lens is clean. Modern manufacturing techniques have rendered lens quality moot in most applications, except for specialty lenses. Experts and camera nerds can tell minor differences, but not most folks.

Generally speaking, a high quality 8x10 in. print should be possible from an 8 MP point and shoot camera. A DSLR should do much better due to the larger sensor area -- at least 11x14 and perhaps larger.
