Camera Raw 7.1 Columnar Color Artifacts

Adobe:  For some reason you wouldn't listen when these problems were reported during beta and you went ahead and released the new version, so I'm not sure I should even bother, but here goes:
Camera Raw 7.1 introduces columnar artifacts in the red color channel (that I've seen), apparently as a result of the operation of the new half-baked defringing features.  I've seen this in a number of images.
Here's a raw Canon EOS-40D file and associated XMP with which you can reproduce the problem. Look at the red channel in the blue water of the pool.

Now convert the same file with version 7.0 (or 7.1 with the Defringe sliders set to 0) and compare the result.
Trouble is, without being able to use the Defringe (Purple/Green) features at all, and considering the Defringe:  All Edges feature has been removed, edge artifacts from the debayering process get to be unacceptable.
Let me spell out for you what you need to do, in case it isn't obvious:
1.  You need to bring back the Defringe:  Off / Highlight Edges / All Edges feature that you had in 7.0 and earlier.
2.  You need to fix this new slider-based defringe facility so that it doesn't do such nasty things to the image. I'd advise you to listen to Vit Novak's input on what else to do to it.
With BOTH of these things done, between the two one could actually hope to get an improved result over the conversions from 7.0.  Fixing the second alone won't cut it.

Back off?  I should heed your expert advice on avoiding confrontation, Jeff?    I have to assume by your unwavering support of Adobe on this issue that you are looking forward to having stylish artifacts like these in your own images.  I guess this will define your new style for 2012.  LOL
All the slack that's going to be cut on this has already been cut.
Hey, I could have just quietly dropped back to 7.0 and just have my own images be superior to those made by those using 7.1, but no - I chose to try to help Adobe by pointing out a problem to them here.
When I reported this problem during the beta, I was clearly ignored.  When I reported it again after the release, I was argued-with.
I don't need to be argued-with nor reasoned-with - Adobe needs to listen to people who know what they're talking about.  People not blindly praising the emperor's new clothes.
I don't need nor expect appreciation, but I had thought I might have earned enough respect around here that Adobe's first response wouldn't be "choose different settings, stupid".
An output image quality problem should be a release show-stopper. Experts like me and Vit telling Adobe that their latest color fringing reduction changes aren't working well enough should be considered seriously. Instead, it's just business as usual: Release whatever's in the pipeline.
Adobe's dropping quality standards are something I find myself wanting less and less to be associated with each passing day.
Just typing this message took me longer than it should have, because of this bogus forum software.
There's a difference between leadership and "too big to fail" thinking.
This is my last post in this thread.  Thanks for your participation.

  • ACR 5.2 camera profiles and Nikon D700 color artifacts

    Using LR 2.2 or Photoshop CS4, conversions of D700 NEFs often result in peculiar color 'artifacts' (posterization?) in certain images, when using the new camera specific profiles like Camera Standard (or particularly Camera Landscape). Typically, the Adobe Standard or ACR 5.2 profile don't exhibit this behavior, at least not with significant changes to saturation and contrast.
    An example of this can be seen at http://farm4.static.flickr.com/3400/3179948383_cfda478eb8.jpg (LR 2.2, Camera Standard profile). Question is whether these sorts of results are expected? I'm otherwise quite happy with the new profiles. Thanks,
    Mike

    Mike,
    1. You may be happy if the problem goes away with the lossless compression, but it would be a nice service to the D3/D700 owners' community to
    b prove
    this. There are many photogs convinced, that the lossy compression does not cause visible loss (Nikon created a myth about this issue already with the D70).
    If you can create pairs of shots demonstrating the effect and would not mind my using your images, I would spread this on other forums as well, as I did with the D300.
    2. Re WB:
    i normally
    you can accept the WB interpretations of different raw processors, but not if the issue is just the WB. The fact, that the displayed color temperatures are close, does not mean much: the color temperature is not absolute. I don't go so far as to say, that it
    i should
    be different between CNX and ACR, but you can not rely on the number.
    Even the snow is clearly reddish in the ACR created JPEG. You may complain about ACR's WB conversion, but that is a separate issue. In order to compare the colors, first the greys have to be made grey in both conversions.

  • Camera Raw 8.7.1 color issues

    After the recent camera raw update to 8.7.1 I have noticed some pretty bad color shifts between camera raw and photoshop cs6. The colors in camera raw look very saturated and then when moving into photoshop the saturation shift is pretty dramatic. I never had these issues before the update. I have attached a screenshot illustrating the color issue. I am working on a very good monitor ( NEC PA 242W ) and it is color calibrated using NEC Spectraview calibration system. I have double checked my color setting in photoshop and camera raw to make sure I was viewing the same color space. I am just wondering if this is maybe a bug in the update and others are experiencing the same issues or if I am just missing something.
    I would also add that I am using the Creative Suite CS6 and not CC. If that makes a difference.

    Thanks ssprengel for the suggestions and running a side by side yourself. I went through all my settings and applied your suggestions and did a side by side each time. I even uninstalled the entire creative suite on my system then reinstalled and updated and I still get the same outcome. It was fine yesterday with the previous version of ACR. It seems like the updated version is not showing the image preview in any color space. When I switch the color space in the workflow options the histogram changes but it doesn't seem to affect the preview window. And yes the preview button was checked on it was just when I was using the screen grab tool in windows it took focus away from the application so that is why the settings appear grayed out. I have attached more screen grabs below illustrating all my settings. Also here is some system info if anyone out there has a similar setup and would be willing to test.

  • Photoshop CS6/Camera RAW 8.8 Inconsistent Color Edits

    I just updated my Windows Photoshop CS6 to 13.01x64 and my Camera Raw to 8.8.0.397. My issue since updating is when I open a RAW file and edit it in that window, when I click 'Open Image' and it converts it into the Photoshop window (to further edit), the colour is very different than it was in the RAW window. Below is an example where I went extreme to show the issue. The left is the RAW window and the right is when it converted to after I clicked 'Open Image'. It's much more muted and the colours are quite different. You can see the difference especially in his face. I'm beginning to feel desperate. Can anyone help?

    I'm not seeing it with CC 2014.2.2 and ACR 8.8, but then again it's a different PS version and different RAW.
    Maybe something happen with color settings in Photoshop?

  • Camera Raw vs Lightroom Color Spaces

    I photographed RAW image of a Gregtag color target with my Nikon D300 and opened it in camera raw in the ProPhoto Color space and adjusted the develop sliders so that the tone squares on the bottom row matched the ProPhoto values, (e.g approx 238,189,144,103,66,37) and ran the Robert Fors calibration script.
    So far so good. I have read that all one needs to do is use the same settings in Lightroom. But when I opened the exact same RAW file in Lightroom and use the exact same develop and calibration settings that I used in ACR, it gives different values for the tone squares. And in fact the values are almost exactly the values for Adobe RGB (e.g. approx 242,200,159,121,84,53). And when I open that file in Photoshop from Lightroom using the ProPhoto color space option the value stay at the same Adobe RGB levels within the ProPhoto color space.
    What am I missing/doing wrong?

    the values in lightroom are not based on prophotoRGB, but on a prophotoRGB-derived space with the same primaries but with a sRGB tone curve. Since adobeRGB has almost the same tonecurve as sRGB, your values came out close. Bottomline is that the values do not correspond to the ppRGB values in ACR.

  • Window Background color in Camera Raw 6.0

    I've recently upgraded to Windows 7 x64 and CS5.  Everything seemed normal the first couple days, but when I opened Camera Raw today, the background color of the window is an off-pink.  The image is fine, but the surrounding background color has changed from the traditional white.  Also, the color around the image previews on the left side is pink-ish as well as the background of the graph on the right.
    This is extremely distracting, does anyone know how to change it back?

    It will be in 6.1, not 6.0.
    See, for example, here:

  • Need to add new cameras to Camera Raw in PS CS2 (not ready to update to CS6 yet).  Can do... how?

    Windows Vista-64, CS2 Photoshop and Illustrator.  CS2 works well for what I do... don't need to update yet.  Need to add Canon 5D Mark2.  When try to open Raw files, get error message: Photoshop says it can't complete the request because it isn't the right kind of document.  I believe this means that the camera is not recognized.  Current DNG Converter is 3.7.  Would like to add Raw support for all newer cameras, so able to work with files from virtually any customer.

    I use camera raw to make preliminary color/brightness/contrast adjustments then save as 16-bit RGB file... then final adjustments in Photoshop.  If I can add (for example) DNG Converter 8.2, to simply allow the CR2 image to open, then I don't need any other features.  What I gain be upgrading to CS6 is additional functionality in Photoshop... no doubt I will be very glad when I do, but meanwhile I only need camera raw as a preliminary step in my workflow.
    Not brain surgery... whatever additional functionality is available in Canon 5d mark 2 that is not in Canon 5d is unnecessary for my purposes now.  Is there a reason that Adobe would not allow adding 5d mk2 (even if not all functionality is enabled)?
    Ideally, I would hope to download DNG Converter 8.2, install it in my Photoshop CS2, and continue with my normal workflow process.  Adobe could easily create a warning that "some functionality provided in certain newer camera files is not available, recommend upgrading to CS6."  Just makes sense to support users as long as possible rather than force the upgrade.

  • Bridge CS6 no inicia camera raw

    hola, tras el cambio del sistema operativo de windos xp a windows 7 (no lo hice yo, no se como reinstalaron los programas), Bridge dejó de abrir camera raw y ajustes de color de la suite, arroja un error que dice que "la aplicacion bridge principal no está activada" consulté en el foro y recomiendan reinstalar pero primero desactivar la suite y verifiqué que photoshop se encontrara activado, y me aparece deshabilitada toda la parte de activar, desactivar la aplicación, asi que no se que hacer porque para desinstalar la suite hay que desactivarla primero. Gracias

    Veo aqui dos problemas, uno en Bridge que no reconoce o encuentra Photoshop,
    y otro de que en Photoshop tienes en gris, no operativa, la parte del menu de Ayuda de Desactivar.
    Lo primero que creo deberías hacer es intentar enterarte de cómo migraron los programas a Windows 7,
    Si tienes instalados otros programas de la Suite CS6, tampoco en ninguno de ellos puedes desactivar la Suite desde el comando en Ayuda?
    (A veces tarda en conectar con servidores de Adobe, comprueba también que tengas una conexión activa a Internet)
    Respecto A Bridge, mira si en las Preferencias (Ctrl+K) en Asociación de tipos de Archivos, aparece o puedes asignar Adobe Bridge a varios formatos.

  • Is it possible to do gradient-based changes between pictures in Camera RAW?

    Say I have 10 pictures. The C-RAW setting for 1 and 10 are different. Is it possible to change the remaining pictures, 2-9, as a gradient between the settings of 1 and 10?
    Thanks in advance

    If the photos were already frames of a video then video editor can do transitions which include brightening to white but you’re talking about individual photos.
    Assuming a Photoshop script (not recorded action, but a hand-coded one via the extend-a-script toolkit) can parse a number out of a particular picture’s filename, if the filenames of the photos were in an increasing order then there is probably some way to apply a numeric transformation of the filename number to a varying brightness value that is applied to a set of raws selected in Bridge, but I have never written such scripts so can’t really give any more specifics about your requested task.
    I am vaguely familiar with Photoshop scripts from a long-since obsolete site hosting the ACR Calibrator script that would operate on a raw photo of the color-checker target and compute color adjustments for camera raw to optimize those colors.  If you are a programmer familiar with JavaScript then this might be enough information to write your own brightening script:

  • Camera RAW + Adobe Aplication Manager

    I need a help! I don't know what happen with my camera RAW. Black color canged into blue. This is happen for all file. When I opened using another app (ViewNX 2) the file work very well. I use Camera Raw 7.1 for Mac.

    Thank you so much for your help! Its a "shadow clipping warning". All blue is gone now.

  • Camera Raw 5.5 - Artifacts in Highlights?

    When opening some raw image files (IIQ, .mos, etc.) on PowerPC G5s running Tiger 10.4.11 & Leopard 10.5.8 in CS4, I've noticed that there seems to be this artifacting that appears in the images in the highlight (say 1-5% dot), and it appears in all 4 color channels. Opening the same files in CS4 on an Intel Mac running 10.5.8, I do not see this artifacting or corruption. If an image is saved that has this artifacting, the artifacting is written to the file.
    I would use CS3 to open these files, but it doesn't support the latest Camera Raw, and thus it doesn't support the latest cameras.
    Has anyone else seen this issue? Does anyone know what might be causing this?
    Please see attachment for an example. Only the blue-green and white should be present, not the varied 4-color outlines.

  • Camera raw changes color in adobe bridge and photoshop

    Hi all, I am quite new to use RAW. I have raw files that I want to edit. Unfortunately, the moment I click on the raw files, the color changes.
    Is there anything I should do to the color setting?
    I am using a canon 20d and Adobe Photoshop, Bridge CS 3 and Adobe Camere Raw 4.0

    The image is indeed rife with red color.
    The fact that the embedded JPEG isn't quite as oversaturated with red as Adobe's conversion with the lowest color temperature of 2000 just says that Canon's conversions have more range at the low-end of the color temperature setting.
    This is the color from the embedded JPEG.  Clearly it's dominated by a reddish-orange color, though not as red as that from Adobe's software.
    This is the color from Adobe Camera Raw's conversion at the (low-end minimum) color temperature of 2000:
    This is the photo converted with Canon DPP using "click white balance" on the bridge beam on the left:
    Note, however, that (though the dropper seems to have incredible range) DPP does not allow you to specifically SET a color temperature lower than 2500K, which yields this color:
    The bottom line here is that the "Click White Balance" function in Canon's DPP has far more range than ACR, where even the white balance dropper "mins out" at 2000K.
    That's something the Adobe folks may want to look into, to extend the range of ACR's capabilities to suit this kind of IR photography.

  • How can I use the color adjustments interface that shows up for camera RAW on jpeg files?

    How can I use the color adjustments interface that shows up for camera raw on other files types? The HLS controls had the secondary color adjustments (6 colors instead of the 3). Plus, it had same vibrancy and a better Curves interface. Yesterday was the first time I imported raw into Photoshop CS5 and I got that really cool interface. What is that? Can I use that on other file formats?

    Actually I am using the Tradional Chinese Version, when I try to edit the jpg file with camera raw, the system shows that there is no camera raw plug-in. The cmaera raw never work.
