I have shot about 8000 images with my D800 and never an issue with moire..until this test shot. I was testing out some settings and shooting a lampshade with a flash and without a flash. The shade is very tightly patterned and sure enough I saw moire in my preview screen.

I downloaded the pics in PS and was reviewing them on my PC and noticed that the moire appears is some 'magnifications' and not in others. But if I look at the pic... at say 25% vs 33% vs 50% vs 100% in PS, there is different moire patterns. And at 100% the actual pattern of the material with no moire.

So my question is.... is moire a factor of the magnification of the 'viewer'?? I thought moire would be in each magnification view and that the moire pattern was actually captured in the pic data stored to the CF card not just as 'viewed.

So am I correct that if you have moire in an image it may be able to eliminate it by saving the image at a different crop magnification??

I could go on but I think you know where I am coming from.
