MOIRE PHOTOGRAPHS Meaning and
Definition
-
Moire photographs refer to images that display a visual distortion pattern known as moiré. Moiré is an interference phenomenon that occurs when two regular and repetitive patterns overlap or interact with each other. It produces a distinctive wavy or rippled effect, resulting in an optical illusion.
In photography, moiré photographs are typically unintentional visual artifacts that arise as a result of an interaction between the regular pattern of the subject being photographed and the pattern of the camera sensor or the resolution of the display medium. This unwanted pattern manifests as concentric or parallel lines, waves, or curves that run across the image, detracting from its overall clarity and fidelity.
The occurrence of moiré photographs can be particularly prominent when photographing subjects with fine regular patterns, such as textiles, woven materials, or architectural structures with closely spaced lines or repeating patterns. Moiré can also emerge when photographing television or computer screens or capturing print material on a digital camera.
Photographers often employ techniques to minimize or eliminate moiré, including adjusting camera angles, altering focus, modifying lighting conditions, or using anti-aliasing filters. However, despite these efforts, the elimination of moiré is not always possible during the image capture process. In such cases, photographers rely on post-processing tools and techniques to reduce the visual artifacts and restore the image to its intended appearance.
Overall, moiré photographs are unintended distortions that can compromise the image quality and clarity due to an interaction between regular patterns. Whether considered an unwanted flaw or a striking visual effect, managing moiré is an essential aspect of photography to ensure accurate and faithful representation of the subject.

Etymology of MOIRE PHOTOGRAPHS
The term "moire" in "moire photographs" is derived from the French word "moire", which means "watered". The origin of this word can be traced back to the Middle Ages when it was used to describe a type of fabric with a wavy or rippling appearance, similar to the pattern created on water. The fabric was highly desirable and often used for clothing worn by the upper class.
In the context of photography, "moire" refers to an undesirable interference pattern that occurs when a regular pattern in the subject matter (such as fine lines or repetitive designs) interacts with the regular pattern of the image sensor or the printing process. This interference produces an unwanted pattern of wavy lines or rippling effects.
Therefore, "moire photographs" are photographs in which this visual artifact is present. The term "moire" was extended from fabric to photographs due to the resemblance of the unwanted pattern to the characteristic rippling effect of watered fabrics.
