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:
- 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).
- 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.
- 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.
