“ According to the dictionary, aliasing is the misidentification of a signal frequency, introducing distortion or error or the distortion of a reproduced image so that curved or inclined lines appear inappropriately jagged, caused by the mapping of a number of points to the same pixel.”

It also happens when you photograph very fine patterns like lines, dots, circles, mostly in fabrics, closely arranged lines in architecture, bird feathers, etc., and this is a result of the sensor not being able to resolve it well.īefore we look at what causes moiré, let us look at what the term “aliasing” means.

When taking photos of something on your laptop, computer screen, or TV screen, you may have come across a rainbow-colored pattern that can be quite difficult to avoid.Some examples of situations where you can observe moiré are: Moiré patterns can happen in many situations, but our focus here will be on moiré in photography where the object being photographed has a pattern that does not match with patterns on the sensor or is difficult to be resolved by the sensor.

Moiré appears as a rainbow or curved pattern or lines. Basically, this appears when you combine two fine patterns and in photography, it is a combination of a manmade or natural fine pattern, with the fine pattern on the camera’s image sensor to create a third pattern called moiré. Moiré patterns or fringes are interference patterns when a fine pattern with very slight gaps like lines, dots, concentric circles, curves, etc., are overlaid on another fine pattern that may have similar characteristics, patterns, or even different patterns.
