Moiré pattern with EOS R6 Mark II.

[adam461]

I've just photographed my second wedding on my new R6Mk2 and I was surprised to see that a few of the images contained moiré pattern, I've been a Canon shooter for over twenty years starting with the D60 and I've never seen it before. Is there anything I can do to avoid it in the future? Will any camera feature/settings help?

Different distance or different focal length will help when you notice moire. Wide open aperture or closed down so that you will get diffraction to soften the image may help.

As Peter said, changing the distance to subject will change moiré.

But if fixing a photo that has already been made, I hope some of this might help: 

If using a Canon lens and saving a raw file, it might be worth trying Canon DPP software "digital lens optimizer" and "color blur" correction. "Digital lens optimizer" might make it worse if it removes the effect of the anti-aliasing filter on the camera sensor.

If your camera has a "clarity" setting, when editing a raw file in Canon DPP software one may set clarity to a negative value which will soften some detail. This might also benefit skin in a photo.

It might help when making the photo to set "clarity" to a negative number in the camera and to use in the camera a picture style other than "Fine Detail".

If you have more resolution than needed, it might be worth trying a median filter or a Gaussian blur followed by unsharp mask. https://en.wikipedia.org/wiki/Median_filter https://en.wikipedia.org/wiki/Unsharp_masking

Unfortunately there's not much you can do to help, modern lenses are so sharp and the focus on cameras is very accurate - the result is that sometimes the pitch of the pixels on the sensor aligns with the weave of a fabric and moire is the result. I saw it more on the EOS R6 than I have on the EOS R6 Mark II. I did find that the moire reduction that can be applied in Lightroom to a mask helps a little, but it's not a perfect fix.
