[QUOTE="WayneF, post: 478586, member: 12496"] Yes, it does not show up well, but I do see it in the blue shirt. But that is not near the 100% size that I meant. That might be 100% of the processed and resampled small final copy, but I am speaking of the original image size from the camera. I fear what you might mean is that if you overwrote the original image file with the processed copy, the small copy might be all you have left now? (in which case, there is no answer left to find... maybe next time?) The D610 image is much larger than your computer monitor screen. D610 FX is 6016x4016 pixels, and DX is 3936x2624 pixels. I don't know your monitor screen size, but almost all are not larger than 1920x1080 pixels, if that. So 100% is much larger than our monitor screen. We can only see a small part of the image then (at 100%). In your photo editor, when showing the original image from the camera (NOT a resampled smaller copy of it), just Zoom your editor view to 100% Actual size. I have not stopped to compute numbers, but that will be so big that about all you can see is maybe like the mans arm and elbow (from the center) Then scroll over to see the shirt, and decide if you see the moire then (at 100% in the original camera image). If you do, it is aliasing in the image, and the camera sampling did it. If you don't, it's not in the image, and subsequent resampling did it. The slight blurring technique works in the second case, and probably not in the first case (although resampling small can help hide it). The D200 at 10mp is about the same sampling susceptibility to moire as the D610 (but their anti-aliasing filters may be different strength). DX in the D610 is 3936x2624 pixels, or also about 10 mp. But that DX size is still at least twice larger than your computer monitor screen, and possibly even larger than that in your editors window. Look at it that large. The editor will specifically call that zoomed view as 100% size, or Actual size. [/QUOTE]
