Verbatim666 Posted January 1, 2010 Share #1 Posted January 1, 2010 Advertisement (gone after registration) I have found this problem on this persons shirt. There are several photos of them, all taken with off camera flash using an M9 + 35mm summicron, 1/30, f5.6 iso160. This is a very low quality jpeg, but with the DNG file in lightroom/photoshop the moire is overpowering. I have read suggestions of desaturating, blurring, blending colours etc. None of them work well, in fact they all look terrible to my eyes. What are others doing in this situation?

wattsy Posted January 1, 2010 Share #3 Posted January 1, 2010 There is not much you can do other than the well documented Photoshop techniques for 'removing' moire. You might want to try Capture One to limit the moire (it won't get rid of it) before retouching. Unfortunately, you had all the classic ingredients for moire - a sharp lens stopped down, flash exposure (providing a very high effective 'shutter speed'), a sensor without an AA filter and a subject wearing clothing with a finely textured or patterned fabric. The reason the problem doesn't crop up more often is that many M8/9 users tend to shoot handheld using available light (which inevitably slightly softens the image through camera shake) and with a more open aperture (reducing the depth of field and making the offending fabric less likely to be in the optimum plane of focus). You could probably have eliminated the moire in camera by moving slightly nearer or further away from your subject or by rotating the camera a little. The trouble is, for this kind of shooting, you are not going to know there's a problem until after the event and you look at the shots on a computer.

wilfredo Posted January 2, 2010 Share #6 Posted January 2, 2010 There seems to be a bit of a Magenta cast on what I am assuming is a black clergy shirt - I wear them all the time :-). I'm using a friends computer on a screen that is not calibrated for photography but I am wondering if others also see a slight Magenta cast? The black jacket looks perfectly fine. What color was the shirt? Am I correct in assuming it was black? Link to post Share on other sites More sharing options...

t024484 Posted January 3, 2010 Share #10 Posted January 3, 2010 Try RawSharpPro. This may probably convert the DNG without Moire. Hans Link to post Share on other sites More sharing options...

Fred Miranda offers a moire removal tool, which is a Photoshop action ( CS and higher versions work). I downloaded it ( 10 euro) and it works quite nice, you can play with the different parameters.

Thomas Thomas One issue for me - Quote"These plugins were developed before CS4 was released so they may not work with it. We are currently testing all plugins for Photoshop CS4 compatibility. Please check back for updates." I use CS4 and this notice has been posted on Fred Miranda site for quite a while. Link to post Share on other sites More sharing options...

chris_tribble Posted January 3, 2010 Share #16 Posted January 3, 2010 Hmm... #1 get the white balance better (see below) - one click on the clerical collar with the WB tool in Camera Raw. Notice how this also reduces the magenta problem significantly. #2 was the Moire this obvious in the full resolution RAW? It can sometimes be significantly reduced by downsizing for JPEG in a series of steps. Worth trying. Otherwise the advice from others is good. #3 Why flash? You'd probably have got better results with available light (especially if you'd used a WhiBal to get the WB right before shooting... #4 re moire overall - I don't find it a significant problem with M8 or M9... but maybe I've just been lucky with my client's dress sense Welcome, dear visitor!

AlanG Posted January 3, 2010 Share #18 Posted January 3, 2010 That may be the price you pay for not having an AA filter. If you can't clean it via the moire filter in C1, then retouching will work. That's what I did and I don't think anyone will even notice the residual moire. Jaap... only 12,804 posts. You slacker. Welcome, dear visitor!
