  • What is moiré? How can we avoid it? - Photography Stack Exchange
    \$\begingroup\$ I recently purchased a Nikon D7100 with 24 3 mp and they have done away with the aa filter altogether to sharpen up the image,I have taken about 200 pictures and so far found no evidence of moire,however I cannot see any improvement of sharpness over my old Nikon D90 when displaying them on my pc!Perhaps you only notice the increase of sharpness when blowing them up or its all
  • moire - Does the human eye see moiré? - Photography Stack Exchange
    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 too small to be recorded)
  • artifacts - What caused this pattern of lines (moire?) in this picture . . .
    This is aliasing, often called a moire pattern when it occurs against something regular, as in this case In this particular case, the actual picture is made of lots of little dots of ink in a regular pattern Your camera sensor is also lots of little sample points on a regular pattern When the spacing of the two are close (or multiples are
  • How To Reliably Trigger Moire? - Photography Stack Exchange
    What is the most reliable way to trigger moire artifacts in an image straight out of a digital camera? I know that resizing an image can cause it but I want to see it all full-resolution and be able to do it reliably so that I can compare two nearly identical cameras that I have here, the Pentax K-5 IIs and K-5 II which differ only in the lack of anti-alias filter of the former
  • post processing - Is it possible to eliminate Moiré patterns from . . .
    Absolutely, it is possible to capture a LED screen in-camera without moiré The Mandalorian show is filmed in a 270° cylindrical projection room, called "the volume" by the production team
  • Why do photos of digital screens turn out the way they do?
    It would be like shrinking the fence grid from the prevois example until it is almost the same pitch as the mosquitoe screen Now that the two patterns are very close in size the moire is much more noticeable Regarding how to remove it: I think that there may be a way of getting (almost) rid of this moire And it may be applying a certain
  • 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 . . .
    Its the moire like pattern that results from stacking the individual photos The photos were taken at 18mm, with a 30sec exposure, an ISO of 4000 and an aperture of f5 6 I first tweaked the exposure and reduced noise in Adobe Bridge, then imported the photos as layers to Photoshop CS5 where I used the lighten filter on each layer to show the trails
  • post processing - What are the strange curved lines appearing on fabric . . .
    If you search for something like remove moire in photoshop you'll find plenty of articles with advice for removing Here's one from photographylife com An alternative is to use a photo editing program like Lightroom that has a tool for removing moiré built-in
  • Blur each pixel independently on sensor to reduce moire effect
    Moire occurs because the scene is sampled at a discrete resolution which is the nature of digital imaging There is nothing to do about that but reduce the frequency of the signal reaching the sensor In fact, moire occurs in monochrome sensors too which have no sub-pixels The matrix of pixels form a fixed grid to sample an image formed by
