May 5, 2013 · Moire is a kind of "aliasing" - an effect where something is seen (or heard) incorrectly because the frequency of the source is too high for the sensor (in a picture high frequency is caused by repeating patterns where the individual pattern is …

But sensors have improved (noise has improved) to allow tiny pixels at very high resolution today, providing sufficient sampling resolution to usually eliminate most aliasing without the filter, including most moire. That anti-moire tool is the higher sensor resolution, actually sufficient now, without the anti-aliasing filter previously used ...

Apr 28, 2019 · Here is a moire effect of several screens causing rosettes: Here is a different kind of rosette pattern (open) There are two different kinds of rosettes depending whether the centres are open or closed.
