Baxter Posted October 27, 2007 Share #1 Posted October 27, 2007 Advertisement (gone after registration) I have just corrected some images using Cornerfix from my ZM21mm. They open fine in LR and corrections are evident. However when I tried opening them using Capture One Beta V4 they were posterised in pinks, whites and yellows - whilst they looked quite unique, they bore little resemblence to the coastal scene of blues, greens and granite.... Files are DNG from Cornerfix. Tried closing C1 and reimporting after redoing Cornerfix ensuring correct profile was used. I thought it made sense to apply Cornerfix correction, then process in C1. Anyone have any fixes or ideas please? Link to post Share on other sites More sharing options...
Advertisement Posted October 27, 2007 Posted October 27, 2007 Hi Baxter, Take a look here Cornerfix and Capture one 4?. I'm sure you'll find what you were looking for!
sandymc Posted October 27, 2007 Share #2 Posted October 27, 2007 Baxter, C1 has historically had some problems reading DNGs correctly, but I thought that was fixed in the V4 beta. First question is what settings did you use on CornerFix? Older versions of C1 required that "Level Compression" be enabled. Sandy Link to post Share on other sites More sharing options...
Baxter Posted October 27, 2007 Author Share #3 Posted October 27, 2007 Hi Sandy I had No compression set when I originally converted. Have just tried with Level Compression set (top box version) and the Cornerfix converted file opens fine in Capture One. BTW there is no evidence of concentric circles etc in the corrected version. Thanks very much, really appreciate this pointer. I hadn't even tried the different settings in your programme because the recommended ones work so well. Is there any benefit on using the Lossless (Huffman) version of compression - assuming that this works too? The reason for trying out Capture One is that I have really struggled to get colour represented the way I like it in Lightroom, despite running the Rags profile algorithm. C1 seems to render things more to my liking. The ability to simplify workflow is important to me - using different developers for different lenses.....

sandymc Posted October 27, 2007 Share #4 Posted October 27, 2007 Baxter, Smaller file sizes are the only benefit to the lossless compression; other than that there's no difference. Personally, I find C1's user interface to be less than intuitive, but I know a lot of people really like the results it gives. Regards, Sandy Link to post Share on other sites More sharing options...
Baxter Posted October 27, 2007 Author Share #5 Posted October 27, 2007 I agree about the C1 interface - it feels strange initially. However it is a grey day, rain forecast tomorrow and I have lots of Leica pictures to 'develop' (and quite a few 5x4's to scan and finish in photoshop...). So have decided to anchor myself at the Mac and see if I can learn the software and crack the C1 nut. Whilst still wearing my L plates, I am much more confident than earlier today and the adjusted files are more 'film-like' in appearance than I've managed in LR.

Have just tried with Level Compression set (top box version) and the Cornerfix converted file opens fine in Capture One. Hi Baxter, it is correct that Capture One 4 beta1 accepts converted/exported DNG with lossless compression only. The current version of Capture One (3.x) does not accept exported DNG at all (like through DNG Converter or Lightroom/ACR export). If you like to experiment with Capture One 4 beta1, you can find a thread here on this forum which contains quite some information. Link to post Share on other sites More sharing options...
sandymc Posted October 27, 2007 Share #7 Posted October 27, 2007 Advertisement (gone after registration) The current version of Capture One (3.x) does not accept exported DNG at all Umm, I don't think that's quite right - it will accept exports from CornerFix if you enable level compression, and disable lossless compression. Or at least it does for me! Sandy Link to post Share on other sites More sharing options...

robertwright Posted October 27, 2007 Share #9 Posted October 27, 2007 I can't get the beta to accept either level or lossless compression of my dngs. Would it matter how I generated the cf file in the first place? Link to post Share on other sites More sharing options...

robertwright Posted October 27, 2007 Share #11 Posted October 27, 2007 iow was there an option to generate the cf file with either of those compression methods applied. I did not notice. basically I am looking for a way to use the c1 beta to process since it does a better job of noise reduction than Lr, I find that the de-vignetting on dark subjects introduces a fair amount of noise in the corners. I also tried the luminance setting, and have to confess I don't understand what it is doing-I would like to only remove the cyan corners and leave the luminance vignetting alone if possible-what setting should I enter to do that?

What should work for doing that in C1 is the following: 1. Level compression on, lossless compression off. 2. Chroma set to 1 3. Luminance set to 0.

robertwright Posted October 27, 2007 Share #13 Posted October 27, 2007 thanks for the speedy reply. I did try level compression but it introduced the gradient rings in some areas of the image. Seems like a fudge right now for C1-hope they get it together. Lr will have to do. thanks:) Link to post Share on other sites More sharing options...

sandymc Posted October 27, 2007 Share #16 Posted October 27, 2007 I did try level compression but it introduced the gradient rings in some areas of the image. You can get rid of that by increasing the anti-aliasing setting, but that increases apparent noise. Aperture or LR are probably your best bet.

Dan States Posted October 28, 2007 Share #17 Posted October 28, 2007 I've been using Cornerfix with C1 LE and like it but find that after I apply it to a file the new file is very dark, and requires about 2 stops of exposure compensation to get back to normal. What am I doing wrong? Thanks and best wishes Dan Link to post Share on other sites More sharing options...
