Arie Intveld Posted April 26, 2009 Share #1 Posted April 26, 2009 Advertisement (gone after registration) I've just shot my first series of images with my new D-Lux 4 since I was able to find a buyer for my D-Lux 3. I find it's not much of a learning curve coming from the D-Lux 3 .. most controls are intuitive. So from a camera handling standpoint, I couldn't be happier. Is it normal for the D-Lux 4's .RWL raw files to have an extreme yellowish green colour cast when Capture One is set to "SHOT" for the white balance? I know that the camera's white balance setting has no effect on the raw files and I'm admittedly a complete neophyte with C1 so this could be attributed to user error. Nevertheless, the files look great once I set the white balance to something other than "SHOT" but the initial yellowy-green colour cast is disconcerting. I should mention that I have not yet updated the D-Lux firmware to version 1.20 .. would the update remedy this? Any thoughts? Link to post Share on other sites More sharing options...

burkey Posted April 26, 2009 Share #2 Posted April 26, 2009 Actually when my DL4 is set to Dynamic B+W I find that the RAW files have yellow cast too. Apparently, and you can read more about it here on the forum, there is "some" interaction with the DL4 between JPEG and RAW files. Check your JPEG settings. . . .

Arie Intveld Posted April 27, 2009 Author Share #3 Posted April 27, 2009 Burkey, I'm a bit relievedto hear that you're experiencing the same. What firmware version are you using? Yes indeed, my problems are associated with RAW+JPG and Dynamic B&W. My settings for JPG in this capture mode are AWB and everything else neutral except for noise reduction (set at -2). I'll search this forum for some insight about how the JPG settings affect RAW files. Thanks Link to post Share on other sites More sharing options...
burkey Posted April 27, 2009 Share #4 Posted April 27, 2009 I have the most recent firmware update. I can't remember the tread where I saw the discussion related to this topic but it's around here somewhere. Good luck. . . . Burkey Link to post Share on other sites More sharing options...
Arie Intveld Posted April 27, 2009 Author Share #5 Posted April 27, 2009 For the D-Lux 4 users following this thread, here is a link to another thread that mentions the green colour cast when working in C1 with raw files captured with RAW+JPG and Dynamic B&W. http://www.l-camera-forum.com/leica-forum/digital-forum/74531-d-lux-4-raw-jpg-parallel.html The theory seems to be that the green filter applied by the camera's JPG engine to produce a "dynamic" B&W is carried into the .RWL raw file as well. The fix is simply to use something other that the "as shot" white balance when converting the .RWL file. Annoying but workable. Anyone else care to chime in?

robbi@laurenson.com Posted April 27, 2009 Share #6 Posted April 27, 2009 Here's the yellow cast in action. These are both RWL previews in C1 Pro, one taken in Standard film mode and the other in DB&W. I want to do a test of all film modes + RAW to see what other effects this may have. Will post when I'm done. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

burkey Posted April 27, 2009 Share #7 Posted April 27, 2009 Advertisement (gone after registration) When I know I'll be working in RAW I leave the film settings to standard color. The first image should look familiar. My understanding is that the DL4 handles RAW files differently than most cameras. This apparently is a "side effect". I think there have been a number of posts/threads about this phenomenon. An eye dropper, (color correction), to the note pad in this shot brings the color back more than enough for more PP. By the way, these are processed with LR2.3. . . . Burkey Welcome, dear visitor!

robbi@laurenson.com Posted April 27, 2009 Share #8 Posted April 27, 2009 It occurs to me since this tint is as the result of WB manipulation it should show up in the RAW file as opposed to being some filter which is inadvertently reflected in the RAW. Does that make sense? Link to post Share on other sites More sharing options...
billyd Posted April 27, 2009 Share #9 Posted April 27, 2009 Just the way the filter is applied to achieve the 'dynamic' BW - shift the white balance. Easily corrected in Raw processing if you also want colour. Same as using a yellow/green filter when shooting BW film. Link to post Share on other sites More sharing options...
burkey Posted April 27, 2009 Share #10 Posted April 27, 2009 Very scary at first but yes, easily correctable in PP. . . . David Link to post Share on other sites More sharing options...
Arie Intveld Posted April 28, 2009 Author Share #11 Posted April 28, 2009 The D-Lux 4 is the FIRST raw-capable digital camera I've used (and I've worked with 7 different digital cameras) where ANY settings from the JPG engine have an effect on the camera's raw file output. Raw output is supposedly direct output from the camera's sensor via the A/D converter .. sans intervention from the camera's JPG processing engine. Hence my surprise when I first viewed my raw files after using RAW+JPG with the Dynamic B&W setting for JPG. I wouldn't expect to see my JPG saturation, sharpening and NR settings affect the raw file either (and they don't as far as I can see). I don't believe the green filter effect on the D-Lux 4's raw files is by design; I rather think it's a firmware bug and, like everything else that utilizes program code these days, full beta testing of a product only occurs when the product is in the hands of the end consumer. We've already seen one firmware update and it's reasonable to anticipate more. Please don't get me wrong; I'm not disappointed with the D-Lux 4. It (along with it's Panasonic sibling) is the most capable small sensor camera available to date. One need only look at the online galleries of Gary Harper or Jim Radcliffe to see what the D-lux 4 is capable of in the right hands (gosh those guys set the bar awfully high!). This yellow/green effect on the raw files is only a nuisance and, as everyone here has discovered, it's an easy fix. I'm happy knowing that my copy of the D-lux 4 is "normal":) Link to post Share on other sites More sharing options...
jaapv Posted April 28, 2009 Share #12 Posted April 28, 2009 It is not the RAW file that is corrupted, it is the WB setting suggested by C4 that is at fault. The displayed image is a suggestion by C4 of a RAW conversion, not an objective rendering of the RAW file itself. There is simply a miscommunication between C4 and the RAW format. I wonder if ACR does the same. Link to post Share on other sites More sharing options...
robbi@laurenson.com Posted April 28, 2009 Share #13 Posted April 28, 2009 It's just a rendering of the WB setting in the camera. Apply the same WB setting using regular film mode and you'll see the same thing going on. There's no miscommunication happening, C1 is faithfully rendering what it got from the RAW file. Desat and you're halfway to dynamic B&W. Link to post Share on other sites More sharing options...
jaapv Posted April 28, 2009 Share #14 Posted April 28, 2009 One thing I really don't understand. Leica firmly supports DNG as RAW format for the DMR and M8, with valid arguments. It is an universal format and the most future-proof of all RAW formats. And then they go and supply a "professional" compact system camera with yet another uncertain proprietary format. One I might add, that ACR for CS3 cannot handle, unless it is converted to DNG in the computer. Giving files that are over 50Mb too. CS4 can handle it, but as I found the upgrade over CS3 is not very useful, that is beside the point. Having said all that, consensus is that the Jpegs from the Dlux4 are so good that there is no real need to shoot RAW anyway. Link to post Share on other sites More sharing options...
