OpenGL and ICM color management

I am looking ways to spend my plugins to use OpenCL and OpenGL to take advantage of the power in modern GPUS.

More specifically, with the Windows GDI, ICM color management can be configured to be automatically done through calls such as BitBlt(), and in fact I do this.

Can anyone here point me in the right direction to learn how we could achieve better color space when using OpenGL in place and place the oldest Windows GDI calls?

Thank you!

OpenGL pretty much ignores the color management - it is up to the developer to manage the color before you go to the GL, or use a shader to implement the correction of the colours inside GL (Photoshop does both, depending on the capabilities of the GPU).

Side note: CIM is just Microsoft implementation of ICC color management standards, a bit like ColorSync is the implementation of Apple.

  • Computer laptop loss during berthing and departure color management settings

    I am running Windows 7 Enterprise SP1 64 bit on a Dell Latitude E6540 with a docking station.  I have calibrated color screen on the laptop as well as an external monitor attached to the docking station.  Whenever I'm disconnecting the computer, the system resets the color management settings and I lose the color calibration on the screen of the laptop.  I have then go manually through Control Panel and re - apply the calibration profile to make things normal.

    I have everything set up so that the calibrated profile is the default profile for the system and I checked this is the case if the machine is docked, but he always loses calibration settings each time.  All drivers of video system are also updated and current.

    Any thoughts or ideas on how to solve this problem?

    Thanks in advance for any advice.

    Hello

    Thanks for posting your query in Microsoft Community.

  • I'm trying to print using my own profile and no color management.   I have found a lead to the Adobe Color Print Utility but reached a point where he declared that she would not work with future versions of the Mac operating system.   I have Mac OS 10,11,

    I have been printing PSD images with my own profiles and color management using an Epson R2880.

    I've now changed to a Mac with OO 10.11.3 and unable to replace the color management.   I found a lead on the Adobe Color printer utility but failed and got a message saying that the utility has only worked with an earlier version of the OS 10.   Is there a way to turn this problem?

    You don't want or need to use the old setting 'No Color Management'. Is no longer the right way to print with a custom printer profile, in the current versions of Photoshop and OS X.

    To use a custom profile to print, use the attached picture settings:

    • In the print dialog box, set the Photoshop color management menu manages colors.
    • Select your profile to the printer in the printer profile menu.
    • In the settings of printer driver Epson (under Printer Setup button) make sure that the Epson printer driver is set to the color - off management.

    I don't know why Adobe Color Printer Utility works in 10.11.3, because I can throw on OS X 10.10 and 10.11. But in the end, it doesn't matter, because you don't want to use it for this purpose Adobe Color Printer Utility is only to print a profiling target, no images. And it won't let you print using your custom printer profile, because the whole point of the utility is to print with no discoloration whatsoever.

  • Between 5.5 and CS4 color management problems

    I'm faced with a problem of color management and would be very grateful if someone could help me with that.

    I'm working to create in inDesign CS4 (6.0.6) and using my usual color management settings. I set up at the bridge in my CS4 and then use in InDesign, Photoshop and Illustrator. My settings are for jobs printed here in the United Kingdom, as follows:

    ---

    Workspaces

    RGB: Adobe RGB (1998)

    CMYK: Coated FOGRA39

    Color management policies

    RGB: Convert in the workspace

    CMYK: Convert in the workspace

    All three 'request when opening' checked

    ---

    Then I have a customer takes the file InDesign me, working there and returned to me to complete the development and execution of the high pdf - are for printing. It runs the latest InDesign CS5.5. I have him ordered to open InDesign and set his Edit > color... settings as follows without any open file is by default (am I do this bit correctly, it will work through all the files I send?):

    ---

    Workspaces

    RGB: Adobe RGB (1998)

    CMYK: Coated FOGRA39

    Color management policies

    RGB: Preserve embedded profiles

    CMYK: Preserve embedded profiles

    All three 'request when opening' checked.

    ---

    We did some testing and it doesn't work. It can open and work on the file ok and I see text changes she did without any problems.

    But when I analyze his record returned in detail, I can see that his record is now showing view > test format > Document CMYK - us Web Coated SWOP (v2)

    that suggests something coming to an end that applies US profile. I can change the configuration of evidence to work: Coated FOGRA39, but prefer the US profile never made his reappearance!

    My apologies if I'm doing a very basic error or errors here, but I usually have my color management just on my own system, so this is new territory for me. If anyone can help with what I should advise him to do to an end, I would be very grateful (she is about 300 miles north of England, so can't easily try the options on his MacBook Pro myself!)

    PS I also noticed that some items on the page have been modified when exporting .idml to 80% of transparency-enough to fool me for a while that the colors had changed over those too, when in fact I don't think that had anything to do with the issue of profile, probably just a bug between economy of process CS5.5?

    The easy way to get your colleague to use the settings that you want, is likely to create a .csf (color settings file) by pressing save button in the Edit > color... Settings dialog box, then having his press office in the same dialog box and selecting your .csf you sent.

  • Updated last Lightroom and color management print arrived damaged

    Hi, I have a problem with printing from Lightroom 6. It seems that since the last update of Lightroom color management has corrupted. Impressions are now far the color range as they were before and as it should. I understand that all would be nice if I could go back to the version of Lightroom before the update. for example, to uninstall the update. Is it possible if yes, how?   Thank you.

    This issue should be fixed in Lightroom to today 2015.6.1 update: http://blogs.adobe.com/lightroomjournal/2016/07/lightroom-cc-2015-6-1-now-available.html

  • My photos in Photoshop and Lightroom are showing very red, but they actually print ok, I tried to change the settings of the color management in Photoshop but it makes no difference.

    It seems that this has happened since changing to 10 Windows, although I change my laptop and it of very well, has anyone at - it had the same problem?

    I also had in the elements, but it is topped by disabling color management.

    Could be a broken monitor profile. Switch display icc profile Adobe RGB or sRGB standard if you have a normal screen space, if you have a screen wide gamut. If this is useful, it is likely that a broken profile.

    In addition, the only way to make sure you see what looks like an impression (on your screen) is to use a unit of calibration as a Culor Munki or Spyder.

    Is there a default value for the color management in PSE10? Beautiful photos from iPhoto, but blur with elements. I need help with this before as I consider that the upgrade to PSE13 and beyond.

    Printing which forms an angle seems ok, but one that is horizontally seems faded, incomplete.

    I was wondering if I saved a layer somewhere and set it as a default value.

    If you group the layers, you will be left with a single layer, thus spreading your concern.

    Suggest that you do the following:

    1. Make sure you have the latest drivers for your printers
    2. Reset the default preferences.

  • By default Adobe color management print affecting RGB to pages B & w and color printing costs

    Adobe Print of default color management seems to be assigning RGB meta pages n & B and cost of printing color for prints n & B.

    I can manually change the color management for printing printer managed on a basis by printing instead of the default adobe color managed

    who "heals" issue, but I don't seem to be able to save this default setting. Has anyone seen and corrected this problem?

    If you want B & W prints, you must use a profile of color B & W. Adobe apps can do know anything about unless you tell them. Just because it seems gray does not mean it is gray on the technical level. You must read on color management. There is nothing wrong with the PS, you're simply using options and incorrect settings.

  • Color management in PS and monitor calibration

    I calibrated my colors of monitors with a colorimeter Eye One Display 2 and for photoshop, I attributed the monitors that he created the color profile to the work area (Edition > assign profile).
    But for photography I take pictures with the color profile setting AdobeRGB on my camera... should I use this instead of that color profile when working on photos in PS? They look a bit washed out. I guess I should continue to use my profile of monitors calibrated instead?

    And photos save a jpg for the web, should I check "ICC profile" box that lists my monitors color profile when registering? Because I noticed that now some browsers began to support ICC profiles. So in Firefox 4 BETA for example, if I do not use the ICC profile setting the colors look washed on other monitors.
    (Note that the ICC profile for jpg setting is available in file > save under... If I go to file > save for Web and devices there embed the color profile that is basically the same thing).

    I was confused in the same way and some time ago I asked a similar question here, but now I think I understand better and will try to explain. I'd appreciate also correction or a confirmation of those who understand this.

    Photoshop like all other color management programs, knows how the monitor displays colors of the color profile that is installed in the system.

    When you use an image with an embedded profile, Photoshop converts the properly display (not the actual numbers) of color values so that the planned colors are displayed as accurately as possible.

    The profiles selected for workstations in the color settings will be affected only in the following situations:

    • When you create a new image, given that it is not replaced in the new options window dialog
    • When in the color settings color management policies are set to perform the conversion of workspace - this will convert the actual number of color values
    • When you choose not to handle colors in the profile attribute in the Edit menu - this will change the display as if the image was created with the current working space profile, will not change the number of color values.

    If an image is with the same color in the system monitor profile then there is no color management past up to the conversion or Proofing color with a different profile.

    It is recommended to work in a popular as sRGB or AdobeRGB color space, because the color management wise when the images are intended to be affixed to the devices and various monitors and more common ground as sRGB is used as a reference instead of a particular monitor color space.

  • Impossible to apply an ICC profile to display. can not understand instructions for color management

    I just upgraded again own computer with Windows7 from my old XP machine.  I have icc profiles for my two monitors.  Under XP, I had nothing wrong with 'apply' or 'associate' or 'use' of these profiles by using the MS color, and both monitors would change appearance when starting a State fully calibrated and profiled.

    Now, in Win7, I followed fairly confusing instructions, go to the color management / devices / select one of the screens / click "use my settings for this device" / add a profile box "Profiles associated with this device" using the add"" button.  Then I click on the correct profile in this box and click "Set as default profile".  Nothing happens.  I can put any weird profile as a default, and nothing happens.

    I don't even know instructions during the effective application of this profile is supposed to happen, but guess it is when you click on "set as default profile."

    "It may be a clue that the color management dialog box fails to identify my poster other than in the form ' generic PnP monitor - NVIDIA GeForce 9800 GT" while the control panel NVIDIA and Windows 'Screen Resolution' box both manage to identify the poster correctly and use their own name i, e, Eizo L768 and Samsung SyncMaster.

    In addition, 'Identify display' in the dialogue box CM works exactly the opposite of how it works in the other two boxes that is Samsung (left) is number 1 in color Mgmt, but number 2 in the control panel Nvidia and Windows 'Screen Resolution' box.

    I'm stuck until I can address this issue, so would be very grateful for any help.

    Thank you

    Thanks the geek for your help.  No thank you somehow to anyone from Microsoft.  None of this reflects well on Microsoft; No to the current Windows 7 CM interface design, not the fact that after years of complaints and messing around with color management that they could have finally gotten the mechanics in place, but still cannot explain, or make it possible for mortals to use it, and certainly not the fact that they create these monsters and offer no support to any well-founded None.  Not a response to a MS person here, not a good answer to similar questions scattered throughout the Web, no after sales support during any period after the purchase of a new operating system of MS qualified (it's supposed to be provided by the OEM, but of course, none of them knows this kind of thing, how can you keep waiting if Microsoft don't?).  So - NO support.

    I can't believe I fell for the hype and purchased a new Windows System.  I swear to you that this is my LAST purchase of windows.  Microsoft, despite the amazing improvements in Win7, still do not understand.

    Here's the answer to my problem, thanks to some photographers and no thanks to Microsoft...

    1 ASSOCIATE YOUR PROFILES WITH DISPLAY AND SET as a DEFAULT value

    To apply an existing ICC profile (ICM file created by any process of calibration), follow these steps.

    Control panel / display / change display settings / advanced settings / color management / color (new!)  / Devices / select one of your displays * 1 / click "use my settings for this device" * 2 / if necessary adds profile applicable to the area of "Profiles associated with this device" using the "Add" button (if your profile is not already listed but is available somewhere on the network or the computer) / click on the correct profile in this box and click "set as default profile."

    * 1 the dialog boxes CM do not label your displays just like the other dialog boxes, they seem to lose the manufacturer and the model number information that is available elsewhere, so your display ABC model nn appears as display: 1. Generic PnP monitor .  Also note that at least on my system, display "1" was in fact display '2' in the other dialogs settings display and vice versa.

    * 2 that could think by selecting 'Use my settings for this device' would mean the Windows using your settings for this device (screen), but apparently it isn't.  That means... Well, I don't know what that means.  Perhaps it means that if you do select not her, even the next step (see below) will not help you.

    Good work so far - unnecessarily complex - and tortuous, but has a certain logic.  Unfortunately it is not nothing at all, until you train the secret key.  Well it seems that the above should do what you want, you need to do something that is quite obvious and not mentioned at all in the General discussion of the help and apparently not known by the 67 people who have read my question.  In fact, it is listed in the section to help Ms... at the bottom of the "Description of the color management settings" and after a largely incomprehensible mass of things that appear not to be relevant, there is a link that is not listed in the content at the top and almost impossible to see... To enable or disable calibration loading Windows

    2 ACTIVATE THE CALIBRATION BY WINDOWS LOADING

    Here's the little hidden from the help file...

    1. To enable or disable calibration loading of Windows, you must be logged in with an account of a user with administrator privileges.

    2. Click to open color management.

    3. Click the Advanced tab, and then click change system default values.

    4. Click on the Advanced tab in the color - default system, dialog management, and do one of the following:

      • To allow Windows to load and display calibrations, check the box use Windows display calibration.

      • To prevent Windows from loading screen calibration, clear use Windows display calibration check box.

    5. Click Close in the color management - default settings dialog box of the system.

    6. Click Close in the color management dialog box.

    Not only it obscure, it confounds even by the fact that you are in the same dialog twice, but the second time is the reference color - default system management instead of the color management as it was the first two times.   But only on the second time is the required box enabled to allow you to check or do a system wide setting.  Easy to miss.

    Experts of either MS doesn't know about it and can not find in the help files or the other, or that they couldn't be bothered to answer my question.  In any case a) I hope this helps someone else, and b) I hope that Mrs. lift their game to support and actually meets the future to frustrated and powerless people that I was.  Thanks Microsoft for losing a day of my life.

  • Neophyte color management problems

    Neophyte color management problem:

    Image rendered PS colors do not match monitor or images rendered with other applications.

    Recall facts: using MacBook Pro retina with NVIDIA GeForce GT M 750 (calibrated in sRGB with ColorMunki Display software), OSX 10.95, PS CS5 and new external NEC PA272 (material calibrated to native with calibrator Spectraview II & NEC gamut) connected with the mini-displayport cable. Although slightly different due to different Mac and NEC display gammuts, a sample JPEG on Mac seems somewhat near NEC as desktop BG on respective monitors images and seen with the OSX Preview app on a monitor. AND the same image in PS when the image PS window is MOVED to NEC, is STILL, UNTIL the mouse is released. Then the image in the PS on NEC image window moves with a glance off the coast of colors. I am aware that the Mac display is sRGB and the NEC a range wide screen, and that this image of the example is a JPEG to sRGB, but I wanted an image that would be displayed on two monitors, with different applications, including the Psalm but it's the same thing when the main PSD used to create the JPEG format is loaded in PS then MOVED over to the NEC. Tried to play with management PS colors and corresponding attempt to different

    Profiles, but no luck. Tried the General searches on Google, but I'm lost. Any suggestions where to start to fix this problem? Thank you!

    The standard behavior in a multi-screen configuration is that Photoshop uses other operating system display profile offers upward so that the display - up to what the image window crosses the line to halfway between them. Then he goes to use the other profile.

    The shift-on-drop thing indicates a video card problem. That's how OpenGL works in Photoshop, when you drag an OpenGL image is temporarily suspended, and then snaps back on when you file.

    So I would try to disable the GPU in the PS preferences or set it to the basic mode. This shifts all display color to the CPU. Then wait for the next update of video driver from Apple.

  • Need help with LR color management

    Hi, well having had about to master the basics of the LR (point 6.1.1) I am happy that I can now treat my image editing, using a combination of Photoshop/plug-ins LR and LR.

    But I'm not about printing. I installed my new Asus monitor today and after a few hours, that it is fixed; If I take a picture of LR and select "Edit with PSE13" and print from PSE the printed output matches against what I see in LR just about perfectly.

    But if I try to print the image live LR is a mess; black out as a blue greenish, or who are green, bluish, and the whole image seems, well just psychedelic.

    I spent hours on it and as far as I can see the print settings in LR and PES look exactly the same. One thing to add; I print on HP Advanced glossy. In LR so I select that paper it will come out a mess, but if I select plain paper it out OK.

    I installed a .icm for Asus monitor file and I put the sRGB mode.

    In LR, I defined as «managed by the printer» color management

    With the HP printer, well it's not quite like the old days, it seems more automated. Under color management, I chose "ColorSmart/sRGB" which is recommended in the manual.

    Windows color management, I chose Asus PA248.icm for the color profile and sRGB Color Space Profile.icm (sRGB IEC 61966 - 2.1) for the printer.

    Anyone has any ideas on what I might be missing / doing wrong?

    Well, I seem to have gotten almost there now. In EPS, I had always managed by the printer color management. The answer in LR seems LR6 handle color management. I now have a good impression. The color match isn't quite right, with the colors on the impression of being a little more clear/more deep, but I'm sure that if I play with sliders to print setting I will get there. Although once I get the Epson printer with its profiles of specific documents, it may very well be right anyway.

  • Newbie question of color management

    Hi people

    using cs4. just finished a CMYK job on a new press. colors on the final print job were pretty loyal to what I saw on my screen when you design, with a few exceptions I want to tweak if possible. I'm new to color management, so looking for some advice.

    According to my research, the right thing to do is to ask a colorsync or icm or icc of my press profile. I did... but my press was a little confused and sent me a bunch of .icc files and I don't know that one to load. people in the press are great people and it's a good press, but I had the feeling that they have not been asked this question a lot. so I ended up using U.S. web coated (swop) v2 profile, which is what they recommended in the end.

    so if I can't get one of my press icc profile, the other approach according to my research wing and adjust the color on my own profile so that what I see on my screen match the printed output. in other words, I take the printed output and hold it up to my screen and manually adjust the color profile settings. I think that this is done in photoshop under edit-> assign the profile and/or edit-> color settings, and then synchronize the color management for all applications using the bridge. Maybe it is possible in indesign? I ask the question on this forum because of the excellent answers that I'll be back here.

    I don't want to screw things up and I'm a newbie with this, then advice out there? My basic situation is that the colors were reasonably loyal but there was a very curious thing where a c = 0, m = 0, y = 35, k = 15 color looked very green on the printed page even if it was a soft yellow on my monitor. I want to try to adjust that.

    Thank you...

    You have a colorimeter and monitor profiling software? It is the starting point of all color management workflow. You also need a pretty good monitor that CAN be calibrated. If the monitor isn't showing you exactly the colors, then nothing do you will to matter.

    Matching the print monitor is an old technique that works only when you have a closed loop where all the work is output on the press even under the same conditions. The purpose of the peripheral use independent publishing spaces, such as Adobe RGB, which is in theory everything correctly calibrated monitor will display the same image, and you can convert any space of output known at the time.

    Terms like watching soft yolks are quite subjective, so I don't know what you expected, but I do not expect 35y, 15 k to be very clear, nor very yellow. While I would not characterize as green color on my monitor, it is certainly not resemble a banana, and beside a clear yellow could be called it greenish in comparison. It's really a yellowish gray clear, in my view.

    I put up a comparison here to see what it looks like, but the colors won't be accurate in a browser.
