erica Posted April 28, 2010 Share #1 Posted April 28, 2010 Advertisement (gone after registration) I am an owner of the S2 since April... I have been shooting in a studio with Pro photo lighting, Beauty dish as a main light.... I have been having a significant moire problem. It happens with a variety of fabrics, solids, and textures. It happens mostly on the 3/4 images. What should I do? Is anyone else having this problem that does work in a studio that uses lighting? The sharpness is amazing in the face. Anyone have any input, ideas, solutions. See two samples attached. Welcome, dear visitor!

wattsy Posted April 28, 2010 Share #2 Posted April 28, 2010 (edited) I have been having a significant moire problem. .... The sharpness is amazing in the face. Unfortunately, the two go hand in hand. I have the same problem with my M9 if I am shooting in good light and am stopped down to around F4-5.6 or so. The lack of an AA filter is very unforgiving when it comes to closely textured fabrics and very sharp lenses (see the resulting mess in the M9 100% crop below). Can you process S2 files in C1 yet? I've found that C1 provides better results when it comes to moire but it by no means solves the problem. If you are able to review things on a shot by shot basis (preferably tethered) you can of course eliminate the moire by slightly rotating the camera or moving a little nearer or further away but this is not a practical solution for everyone. The other option is to introduce your own virtual 'blur filter' by drinking lots of coffee and shooting hand held with lower shutter speeds (or not using strobes which provide an effective high shutter speed).

If it's portraits you are shooting a little softening would do no harm anyway, a slightly greasy filter would do it. Kevin. Quote Link to post Share on other sites More sharing options...
c6gowin Posted April 29, 2010 Share #4 Posted April 29, 2010 Hi Erica and welcome to the forum. I wished I had an easy answer for you, but I don't. Sorry. I have noticed moiré in a few of my S2 photos and so far I have been lucky because it hasn't occurred in photos which I considered keepers. I searched Google and found a few helpful discussions on how to prevent and remove moiré. The suggestions provided by Ian Watts above were repeated in several of the google hits. There were also some Photoshop techniques to address moiré. Perhaps you can find something that works for your circumstances. Please let us know how you fare.

sandymc Posted April 30, 2010 Share #5 Posted April 30, 2010 If you're using anything other than LR for the raw conversion, then change to LR (or Camera Raw) - other converters, notably C1, aren't correctly tuned for the S2's files.

erica Posted April 30, 2010 Author Share #6 Posted April 30, 2010 There is no processing involved. The native RAW is DNG. Quote Link to post Share on other sites More sharing options...
mjh Posted April 30, 2010 Share #7 Posted April 30, 2010 Advertisement (gone after registration) There is no processing involved. The native RAW is DNG. There is always some processing involved … Unless you are dealing with JPEGs (in which case the processing is performed in-camera) you will have to use some raw conversion application to turn the raw data into an image. A sensor without an antialiasing filter will create very sharp images that will also be susceptible to moiré; there is no way you could get one without the other. That is why the raw converter needs to either actively avoid creating moiré or to suppress moiré, and some converters are better at this than others.

Guest dav_k Posted May 1, 2010 Share #8 Posted May 1, 2010 Erica, Can you provide these raw DNG files from the camera? David Quote Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted May 1, 2010 Share #9 Posted May 1, 2010 Getting Moire is caused by hitting the nyquist value of the lens , basically pinpoint sharpness and it happens in all MF and even in 35mm world although far less with AA filters since they are designed to do that. Anyway C1 does have a moire tool that helps but the best approach really is avoiding it when in studio when tethered and you spot it. I do this quite often when I am shooting displays I get moire quite a bit. Simple trick is to actually back off on focus and stop down more. What you are basically doing is getting away from the nyquist value and de sharpening it than bring back the sharpness through stopping down a touch. Not perfect but it does help. BTW this happens and can happen with any decent quality lens. Believe it or not all the 6 microns sensors from Dalsa and Kodak are actually better than there 6.8 cousins on moire.

I cannot post them here, they are too large. Quote Link to post Share on other sites More sharing options...

AlanG Posted May 7, 2010 Share #12 Posted May 7, 2010 (edited) Apple Aperture has a Moire Slider "worked w/ my M8" attached 100% crop Hope it Helps You still have a blotchy wall. I tried the top posted images in C1 using its slider and even fully de-saturated the moire pattern remained. Trying to anticipate and compensate for moire in advance will not always be easy and the solutions of de-focusing or stopping down could be worse than if the camera had an AA filter in the first place.

You are right.... However, it reduces it a bit which is a little better. "it was just a suggestion" I should've mentioned it as another option.

However, it reduces it a bit which is a little better."it was just a suggestion" I should've mentioned it as another option. Thanks for the replay AlanG I wasn't trying to criticize you. It is just that sometimes moire can't be removed other than via manual retouching. I've seen the C-1 software work pretty well but not for anything as severe as the first examples. Perhaps C1 would do better if it is used on the raw file. In your image, the color around the wires and vertical posts seem similar to moire but really are aliasing effects and not from light interference in fine detail resulting in a pattern. Although both are caused by the same thing - lack of an AA filter. Edited May 9, 2010 by AlanG Quote Link to post Share on other sites More sharing options...
Vladimir Sadov Posted May 12, 2010 Share #15 Posted May 12, 2010 On the subject of moire, I would like to share an amusing observation: The Leica S-system owner's portal owners.leica-camera.com has on top a photo of S2 with 3 lenses, set on some kind of a textured background. Guess what? It shows severe moire. Maybe they meant it to serve as a sort of a warning Or maybe they so got used to it, they do not notice it anymore?
