How to Reduce Moiré in Lightroom 4 by Nasim Mansurov.

The weaker antialiasing filters become on cameras (and it IS a trend) the more important moiré handling in software is:

 

"As you may have noticed, I used the word “reduce” instead of “remove” in the header of this article. That’s because the moiré pattern often cannot be completely eliminated with a non-destructive editing application like Lightroom (except for mild cases of moiré), especially when moire

damages the texture. Photographs with very visible and large moiré patterns in the Luminance Channel can only be completely fixed in Photoshop, which is a cumbersome and time-consuming process. In many cases, you have to sacrifice details to remove moiré completely. This is the reason why I have been recommending most of our readers to buy the regular version of the Nikon D800 instead of the D800E. The latter is a specialized tool for dedicated landscape and macro photographers that want to get the best out of their equipment. The last thing you want is introduce another step to your workflow in order to clean up moiré, just because you picked up the wrong camera.

Please note that the below instructions will only work with Lightroom 4. The previous versions of Lightroom do not have any moire reduction tools. Please also note that the below tool works best with the original RAW file."
