Below we list common digital camera and image resolutions, and show what their top images translate into when printed. Even today's high-end cameras can't produce images for large prints at 300 dpi to approximate the sharpness of a standard film photo. But even low-end cameras can yield prints that look reasonably good at 4 by 6 inches.
