How to Deal with Moiré in Your Images


On this video  photographer Gavin Hoey takes a look at a known problem called Moiré pattern which  is a problem you might encounter when photographing portrait and architecture.

Moiré pattern as Nikon explains it is:

Caused when a fine pattern in the subject (such as the weave in a fabric or very close, parallel lines in architecture) matches the pattern of the imaging chip. When two patterns meet, often a third, new pattern is created. This third pattern is called moiré. 

There are a number of ways to avoid this usually unwanted phenomenon and in this video Hoey talks about 3 of them:

  1. Remove the element causing the pattern (for example the shirt with the pattern). This isn’t possible every time though (for example in architectural photography).
  2. Close down the aperture (to about f/11 or slower). This is again not always an option, depending on the lighting conditions, your subject and what you want from the image.
  3. Remove the Moiré (both Lightroom and Photoshop have features which allow you to remove Moiré.

We have looked at how to remove Moiré using Photoshop on a video photographer Mark Wallace a few years back which you are also welcome to check out.
