sean_reid Posted August 31, 2007 Share #21 Posted August 31, 2007 Advertisement (gone after registration) I'm not sure why every issue with the M8 discussed here has to be given the full Panglossian spin. I think most people accept that the 'rainbow' colour moire effects are an unavoidable byproduct of sharp lenses, mild/missing AA filters, and fine frequency detail. What is new to me (though Bob has demonstrated it also happens with his Canon) is the addition of the maze-like geometric pattern effect. Unlike straightforward colour moire, I find the maze patterning effect less easy to remove (the effect is visible in both luminance and colour channels). Ideally I would like to be able to deal with the issue at the RAW conversion stage without globally softening (or otherwise reducing the detail of) an image. I'm most familiar with C1 - do any of the other RAW converters make it easier to reduce these geometric artefacts without reducing the detail on a global basis? The full Panglossian spin? What in the world does that mean? Since you quoted me, I'm curious. As to your question: The best tool I've found is the C1 Moire correction plug-in that works in Photoshop. I dial it in as needed and then revert back one state and use the history brush to paint the corrections in only where needed. That leaves most of the picture file unaltered.

Bob Ross Posted August 31, 2007 Share #22 Posted August 31, 2007 Hi Dav, You can also see it in the grates under the windows on the left side of your picture. I did a quick check with PWP's moire tool and got the same results as Bob, so it can be fixed. When I first got my M8 I ran around trying to get moire to see how bad it was and learn how to fix it. I didn't have any luck, but I was shooting JPEGs at the time. Bob Link to post Share on other sites More sharing options...

Too bad it doesn't work in CS3 for Mac. Link to post Share on other sites More sharing options...

sean_reid Posted August 31, 2007 Share #25 Posted August 31, 2007 Too bad it doesn't work in CS3 for Mac. Really? I hope they fix that. I'm still using CS2 and the moire correction is a great little tool. Cheers, Sean Link to post Share on other sites More sharing options...
barjohn Posted August 31, 2007 Share #26 Posted August 31, 2007 They acknowledge the problem in the forum on their web site but don't give any expected fix date. Looking at info it appears to be a Power PC file as opposed to native Intel file. Maybe the Windows version would work if dropped into the Mac but I haven't tried that.

adan Posted August 31, 2007 Share #27 Posted August 31, 2007 Advertisement (gone after registration) 1) Pangloss - Wikipedia, the free encyclopedia "We live in the best of all possible worlds" and all that - the proper response to which, in Jack Nicholson's words from the eponymous movie, is - "What if this is as good as it gets?" I have my doubts about either possibility... 2) I guess I am surprised that this kind of maze-moire is unfamiliar to some here as a standard artifact of digital imaging. Go to dpreview.com and study the review images of such expensive "pro" and cheap "consumer" cameras as the: Kodak 14n, Nikon D70, Canon 1-D(whatever). It is, in fact, rather common: Nikon D70 Review: 17. Photographic tests: Digital Photography Review (scroll halfway down page). 3) Yes, the RAW interpreter can have an influence on how obvious the moire/maze is, or even different versions of the same software. When I first got the M8 and used my pre-M8 version of ACR (3.4??) I got bayer interpretation mazes in really bright reds (like illuminated taillights). When I upgraded to the next version in Dec., it went away completely. Link to post Share on other sites More sharing options...
KM-25 Posted August 31, 2007 Share #28 Posted August 31, 2007 I find it very simple to correct using the C1 Moire plug-in for Photoshop. This is the trade-off for the superb resolution we get with no AA filter. My own preference would be for all of my cameras to have no AA filter. It's a small consolation, but moire like that is evidence that your lens provides a lot of resolution. Cheers, Sean Sean, where do I get this plug in, I have the same problem, a lot people do. This is one reason I looooove film...:-). Link to post Share on other sites More sharing options...
sean_reid Posted September 1, 2007 Share #29 Posted September 1, 2007 Sean, where do I get this plug in, I have the same problem, a lot people do. This is one reason I looooove film...:-). It comes with C1 Pro and one is given the option to install it after installing Pro itself. I don't think it comes with LE. It's a great little tool that I've been using for years. Yes, film is easier in some ways. Cheers, Sean Link to post Share on other sites More sharing options...
