Problems with Digital Photography That May Occur

Since the light sensitive component in a digital camera consists of discrete pixels, problems of Moiré, or interference patterns may occur when photographing fine patterns, such as textiles, geometric figures, and computer or TV screens. . However, this is not a problem for most real-life situations.

"Highlight burn-out" is also a potential problem. Depending on the contrast of the subject, the lightest parts of the image may be so over-exposed that there is no image information, other than total white, in these highlights. Also, the reverse may occur.

Shadows parts of the image may become murky to totally black, because of the inability of the camera's sensor to cope with the contrast. The image at right shows both these conditions simultaneously. Some digital cameras can show these blown highlights in the image review, allowing the photographer to reshoot the picture with a modified exposure.
