- What is moiré? How can we avoid it? - Photography Stack Exchange
What is the image defect called "moiré"? What causes it, and how can we avoid or reduce it? Is it related to "false color"?
- post processing - Is it possible to eliminate Moiré patterns from . . .
Absolutely, it is possible to capture a LED screen in-camera without moiré show is filmed in a 270° cylindrical projection room, called "the volume" by the production team Rather than using CGI in post, the scene's background elements are projected in real time on the LED screen, and captured at the same time as the actors in camera There is no moiré in that show
- Why do photos of digital screens turn out the way they do?
3 As other answers state, the effect is called Moire But why does it happen when you downscale or zoom-out? As prevoiusly stated Moire happens when two patterns interact, specially if the two patterns have a "frequency" (read size of the repeating characteristic) close enough to each other
- How does an anti-alias filter affect image quality other than reducing . . .
The commonly stated trade-off for using an anti-alias filter or not is that it diminishes the risk of moire while also reducing potential sharpness This is what I have seen myself and in many online
- image processing - Photography Stack Exchange
Moire patterns caused by sampling a continuous image are aliases The same math applies to them just as it applies to high frequencies aliasing into a audio stream and sounding like background whistles It's the same stuff, with the same theory to explain it, and the same solution to deal with it
- astrophotography - What causes and how can I avoid this moiré pattern . . .
The moire like pattern only becomes apparent on flattening the image I tried another series of images that were taken facing south and didn't get the strange effect
- does the presence of Moiré in a photo implies the lens outresolve the . . .
As to your question about producing moire patterns when the sensor has higher resolution (resolvable line pairs) than the lens: I'm skeptical that that's possible, since an optically blurred image can't be sharpened by using more pixels You'll just get a better final image print of the blur itself
