gmaurizio Posted November 13, 2007 Share #1 Posted November 13, 2007 Advertisement (gone after registration) Moire is supposed to happen only in certain circumstances. Golf is one of them. So far attempts to mitigate have been futile. C1 Pro refuses to deal with it, since it is not a Pxx back. Any hints? All regular recipes *bluring b channel and the like* failed. Thanks!

Advertisement Posted November 13, 2007 Posted November 13, 2007 Hi gmaurizio, Take a look here M8 Moire. I'm sure you'll find what you were looking for!
robertwright Posted November 13, 2007 Share #2 Posted November 13, 2007 I posted a while back about a photoshop moire plugin from capture one, if you go to their website they have an archive section of old releases, and if you find capture one DB 3.7.1 and download it, in the extras folder on the disc image there is the plugin you can install and run. It works and would handle this easily. (mac afaik-maybe they have a pc version not sure) versions of capture one db after (3.7.2) had the moire plugin built in and will not work. hth. i can yousendit to you too.

zlatkob Posted November 13, 2007 Share #3 Posted November 13, 2007 The pants are very gray, so once you select them with the selection tool in Photoshop, bring the saturation down to about -75 or lower. They will look nearly the same, but without the colored moire. If the gray then looks too cold, you can select the pants again and add just a touch of yellow and red in the color balance. Some weird patterns will still be there, but they'll be small and should be much less noticeable without the color. Link to post Share on other sites More sharing options...
robertwright Posted November 13, 2007 Share #4 Posted November 13, 2007 processed in c1DB anti-moire plugin- i think the artifacts are from jpegging over and over, the dng's I have processed have been fine. You might need to go in with a history brush and restore some areas where it is too aggressive. I do a selection first before I launch the plugin to speed the computation and limit the collateral damage. Welcome, dear visitor!

dlw Posted November 13, 2007 Share #5 Posted November 13, 2007 FYI, the plug-in doesn't work with Photoshop CS3. Link to post Share on other sites More sharing options...
robertwright Posted November 13, 2007 Share #6 Posted November 13, 2007 FYI, the plug-in doesn't work with Photoshop CS3. and cs2 is "unsupported" in leopard, which makes me not long to upgrade. I guess I will be keeping cs2 on the disc for the times when I need this plugin, not to mention old scanners, etc... sigh. thanks for the heads-up Link to post Share on other sites More sharing options...
sean_reid Posted November 13, 2007 Share #7 Posted November 13, 2007 Advertisement (gone after registration) I also use the C1 Moire plug-in with CS2. I apply it globally, then back off to the previous state and apply it only where needed using the history brush. Cheers, Sean Link to post Share on other sites More sharing options...
KM-25 Posted November 13, 2007 Share #8 Posted November 13, 2007 This is one of the main reasons I do not use the M8 for advertising work. I just don't have time to deal with it. In editorial it might run smaller so it is not as big a deal.. Link to post Share on other sites More sharing options...

(Now, if I could just get C1 to stop crashing while building thumbs and previews . . .) Link to post Share on other sites More sharing options...
carstenw Posted November 13, 2007 Share #10 Posted November 13, 2007 KM, are you saying that it is faster to sharpen every image than to use the anti-moiré plugin for just those images which have moiré? Link to post Share on other sites More sharing options...
robertwright Posted November 13, 2007 Share #11 Posted November 13, 2007 This is one of the main reasons I do not use the M8 for advertising work. I just don't have time to deal with it. In editorial it might run smaller so it is not as big a deal.. While I feel your pain, moire is a "feature" of every medium format digital back like leaf and phase. That is why their capture software has these tools to deal with it. In studio we get to deal with it usually as we are shooting, either by backing up slightly or twisting the camera a few degrees, sometimes it goes away. On some fabrics, nothing you do will make it go away, so out comes the software. The only cameras that don't feature this are the ones with filtration like canon and nikon, so your classification breaks down there. It is a pita tho, I do corporate work with it and I am guaranteed "guys in ties" as subjects, so if I had to hand off an entire disc of tiffs it would be not worth the hassle, so I agree. This is actually a case for better jpegs out of camera-handingn off a disc of full res jpegs is not uncommon, or sending the entire shoot as small jpegs fpo does happen. I would not be comfortable doing that. The plugin works fine. One stop. Link to post Share on other sites More sharing options...
gmaurizio Posted November 13, 2007 Author Share #12 Posted November 13, 2007 Thanks to all for your insights. Our medium Imacon and Kodak DCS never produced this kind of Moire. Neither did our Kodak DCS SLR pro... Well, I guess no more golf for the M8. You should see some other people shirts!!!! They look like the hotdog mustard spilled all over. I will try the plugin, thanks for pointing out how to download it Robert. Link to post Share on other sites More sharing options...
gmaurizio Posted November 13, 2007 Author Share #13 Posted November 13, 2007 Is it possible that the C1 moire plugin DOES NOT work in Intel Macs at all? Both CS2 and CS3 refuse to load it... Link to post Share on other sites More sharing options...
gmaurizio Posted November 13, 2007 Author Share #14 Posted November 13, 2007 Plugin DOES work in CS3 in PowerPC macs! Glad I save one of them (or two...). It works fine, lots of options. Thanks Guys Link to post Share on other sites More sharing options...
ChrisC Posted November 13, 2007 Share #15 Posted November 13, 2007 Gus - 30 seconds work in Photoshop: On duplicate layer take a good colour sample of the material, with a paintbrush set to 'Colour' paint the material [@ 100%]. Easy Peasy. .............. Chris Sorry about the shrinkage, still having problems posting images, the file was fine at 100% download size. Give it a try. Welcome, dear visitor!

cmb_ Posted November 13, 2007 Share #18 Posted November 13, 2007 FYI, the plug-in doesn't work with Photoshop CS3. The Phase One DeMoirize plugin works in CS3 on Windows. Must be only a problem on Mac. There is also a FM action available for moire. Link to post Share on other sites More sharing options...
AlanG Posted November 13, 2007 Share #19 Posted November 13, 2007 I think there is some confusions here as I don't believe the patterns in this example are moire. They are a maze like pattern from the demosaicing process of the raw converter. I can't say if you can expect the DeMoirize plugin to do a good job on it. (It may help remove the color but the pattern will remain.) The unreleased version 5 of DxO claims to be an improvement in this regard, but I don't believe it will support the M8. If you go to this link and click on the letters A,B, and C of the first example you will see similar maze artifacts: A new generation RAW converter Link to post Share on other sites More sharing options...

I had to give up the Kodak SLR/n because of moire and christmas tree lights, having a fix that takes just 30 secs is a non starter when you have 300 images you need to get in the post. My quick fix was a rough selection with the paint brush then desaturate. Kevin. Link to post Share on other sites More sharing options...
