Patterns formed in portions of a photographic image as a result of confusion between a pattern within the photographic scene and the pattern of pixels within the sensor. Moiré can often be eliminated, or greatly reduced, by moving either closer to or farther from your subject. Higher-resolution imaging sensors tend to be less prone to issues with moiré, which is a form of aliasing.bhphotovideo
Pronounced Mwa-ray, a pattern of light and dark colors or bands created when two repetitive patterns that differ in orientation or frequency are superimposed in an image.
A visible pattern that occurs when one or more halftone screens are mis-registered in a colour image. Often produces a coloured checkerboard (or rainbow) pattern.
– A wavy pattern that can appear when the object being photographed has repetitive details that exceed the resolution of the image sensor. Intricate fabric weaves, the screens in windows and even hair can produce moiré.

An interference pattern created when a repeating pattern in the subject is overlaid on the image sensor grid. In Nikon D-SLRs, moiré is greatly reduced by means of advanced image processing algorithms and optical low-pass filters.
