Display Profiles

Not entirely sure where this topic should be posted...
I seem to be having an issue with display profiles/preferences. All of a sudden, when I switch from one user account to another the display appears way too bright, and the system doesn't apply the correct monitor profile, showing "Generic RGB Profile" in system preferences. Selecting "Calibrate" from the display prefs, it says, "Can not calibrate the display" and "The factory profile for the display could not be found." I have calibrated/profiled the display with a Monaco EZcolor and all seemed fine for a while. On reboot, the profile reverts to the correct one.
Thanks

The script works. Not sure what happened the first time I ran it. Test it out, and see if it works for you.
Paste this into a new Script Editor document. Save it as either a script or application. A script will allow you to run it from the Script Menu, while apps can be added to the Login Items and run from the Script Menu.
===============
display dialog "Running DMProxy Color Bug Fix. You may be asked for the password of an administrator on this Mac."
do shell script "/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks /CoreGraphics.framework/Versions/A/Resources/DMProxy" with administrator privileges
display dialog "DMProxy color fix applied."
===============
This script will run DMProxy without launching the Terminal, so you will not have to close it when done. That's what I like about it. I'm going to use it from now on.
The script will let you know that it is running, and that you will be asked for an admin password. You can remove the second "display dialog" line, at the bottom, if you don't want to be notified when it's finished. The first one should stay in place, however, because you always want to know why you are being asked for a user name and password. Without the dialog, "System Events" will be asking you for a password, and you will not know why. Never enter a password unless you know why, as malware could potentially ask you for a password, and entering without knowing what it's for is dangerous.
Good luck with the script!

  • Display Profile No Longer recognized in Final Cut Pro After Mavericks Upgrade

    I have a 27" 3.4 GHz I7 imac. and an Apple 30" Cinema Display  After the Mavericks upgrade my viewer window suddenly has completely crushed blacks and is extremely dark.  Projects previously exported out look perfect in both Quicktime and Preview. I can export a project and it looks fine, just terrible in FCP.  It seems that it is related to my calibrated display profiles.  FCP will not recognize them now under Mavericks and worked fine with Lion.  Switching to the generic imac or cinema display profile will hold after the change and make the viewer look normal.  I downloaded FCP 10.1 didn't fix it.  Any ideas why this is happening now?

    After researching this quite a bit and seeing this Very very dark video in FCP X viewer. I was able to fix the problem by building a matrix based profile. This problem dated back to the first FCP release for some, but I never experienced it until updating to Mavericks.  It seems that Mavericks is the problem, since nothing changed with FCP. I read somewhere else that another color calibration software tool was having an issue that Maverick's broke LUT (Look Up Table's}  I'm surprised that I am not seeing more photographer's/videographers with this issue. It may just be that those that are using calibration don't have softaware that builds LUT profiles by default.

  • Display profiles and soft proofing Windows RGB / Monitor RGB

    This might have asked before, but I did not find any definite answer for this. Sorry this gets a bit long.
    Short question:
    What's the difference between softproofing with Windows RGB and Monitor RGB targets? I see differences in my image between these targets.
    Long question(s):
    Here's some reasoning.. let me know when I go wrong.
    I have hardware calibrated my display Spyder 3 elite to sRGB standard. I have understood that the generated display profile contains a LUT table that affects gamma values for each RGB component, so that affects both gamma and color temperature. That table is loaded into video card when Windows starts. In addition to the LUT table, the display profile contains what? Probably information on what color space the display has been calibrated to. Does that matches directly with the LUT table information, but may deviate from sRGB in the case my monitor cannot reproduce sRGB 100%?
    Now if I have image that that is in sRGB, but the embedded sRGB profile has been stripped away, should any non color management aware image viewer show the colors properly, if it is assumed that 1) my monitor can handle full sRGB space and 2) my monitor was succesfully calibrated to sRGB and the LUT table has been loaded into video card?
    Or does it still require a color management aware program to show the image, which implies that the LUT table information alone is not enough and the display profile contains some extra information that is needed to show the image correctly? I would think this is true, as I needed to turn on color management in Canon Zoom Browser to see images in it the same way as in Photoshop.
    Now to the original question, what's the difference in Photoshop when soft proofing with Windows RGB and Monitor RGB targets
    I read from www.gballard.net that
    Photoshop can effectively "SoftProof" our web browser color:
    Photoshop: View> Proof SetUp> Windows RGB
    Photoshop's Soft Proof screen preview here simulates how unmanaged applications, web browsers, will display the file on 2.2 gamma monitors, based on the sRGB profile. If the file is based on sRGB and our monitor gamma is 2.2 and D/65 6500 degrees Kelvin, we should see very little shift here, which is the goal.
    Photoshop: View> Proof SetUp> Monitor RGB
    THIS IS WHERE the color-brightness-saturation problem will repeat consistantly.
    Soft Proofing Monitor RGB here strips-ignores the embedded ICC profile and Assigns-Assumes-Applies the Monitor profile or color space.
    The color and density changes seen here show the difference between the monitor profile and the source profile sRGB.
    I'm not sure how to read that. Assume here that my monitor has been calibrated to sRGB and the PS working space sRGB. Do in both cases photoshop strip away color profile from the image at first? What happens after that? Does in Windows RGB case Photoshop pass the color values as they are to display? What does it do in "Monitor RGB" case then? Does it assign my monitor profile to the image? If it does, does there also happen conversion from one color space to another? In either one conversion there must happen as the soft proofing results are different. Does either one cause "double profiling" to the image as the monitor is already calibrated?
    Thanks

    Windows defaults to sRGB if you don't calibrate your monitor so untagged sRGB files should display (more or less) correctly in applications that don't know about color management on systems with uncalibrated monitors.
    When proofing against Windows RGB you're proofing against sRGB, it will show you how applications that don't know about color management on an uncalibrated monitor will show the image. This is what you proof against if you want to see how the image will display in web browsers.
    When you proof against Monitor RGB, Photoshop will assign your monitor's icc profile to the image which tends to be utterly useless most of the time.

  • Memory Leak in Preview.app when switching Display Profiles

    I found a weird memory leak in Max OS X Preview.app, which manifests itself when Display profiles (color calbration) is change. I wonder if anyone else can reproduce my experience.
    1. Open up "System Preferences" -> "Displays", switch to the "Color" tab. You'll need at least 2 available profiles in the list. (If you only have 1, you can create another using "Calibrate..." button to launch Display Calibration Assistant.
    2. Open an image file in Preview.app.  The larger, the better. Zoom in full size to maximize the effect of the bug. I repro'ed easily with this image: http://www.donporter.net/NewSchool/Color/Examples/Printer%20Test%20file.jpg
    3. Open up "Activity Monitor.app", and click on Preview to highlight it, so you can watch its memory usage.
    4. Switch back to "Diplays" Preference Pane. Using the arrow keys, toggle up and down between two different Display profiles.
    4a. At the same time, watch Preview's "Real Mem" in Activity Monitor, as well as the total "Active" memory.
    5. Each time you switch profiles,  Preview consumes more Active/Real memory, about 25MB per switch in my case. This continues until all physical memory is consumed, and then (I presume) starts swapping virtual memory to disk.
    6. Bring Preview to  foreground, and all the profile-induced memory usage is freed.
    Weird, wild stuff.

    Could it be possible that this is just the OS holding the memory for the app until another process requires it?  Do you find that the memory increase eventually causes the app to become unstable? 
    It might be best to open a new bug report on this over at bugbase.adobe.com.  When adding the bug, please include any source code, project or installer that will help us reproduce the issue internally.  If you'd like to keep your code private, feel free to email it directly to [email protected]  Once entered, please post back with the URL so that others effected can add their comments and votes.

  • How to get the POSIX path of a display profile under 10.6?

    Hi forum,
    I'm currently struggling with an AppleScript that returns the POSIX path of the profile of the 1st display just fine when run under OS X 10.4.11. But under 10.6, I can't seem to get it to work, it raises 'syntax error: Expected “,” but found identifier'.
    tell app "ColorSyncScripting"
    set prof to location of (display profile of display 1)
    try
    POSIX path of prof
    end try
    end tell
    (I should probably mention that I try to run the actual script from the commandline using osascript - ie. `osascript -e 'tell app "ColorSyncScripting"' -e 'set prof to location of (display profile of display 1)' -e 'try' -e 'POSIX path of prof' -e 'end try' -e 'end tell'`)
    Any suggestions are appreciated.

    The ColorSync scripting extension relied on FSSpecs and was not 64-bit compatible. Apple dropped it entirely, along with huge chunks of the ColorSync API for which there are currently no publicly documented replacements. You'll have to do it in C.

  • Display Profile location in 10.8

    I've created a new display profile under the Color tab in Display options.  If I highlight the new display profile name, it tells me the location is ~/Library/ColorSync/Profiles.  However, I'm not seeing it in there.  Am I missing something here? Is the file hidden?  I'd like to find that icc file and copy it to a few other machines of the same make/model.

  • Color display profile

    I have noticed that the colors on my Air and IMac differ substanitally.
    My Air (and my wife's Macbook Pro) have a default color profile called "Color LCD"
    My Imac's profile is called "IMac"
    The colors running Color LCD are more red.  This is especially noticeable on the Air.  If I change the profile to sRGB on the Air then the colors more approximate the IMac colors but not exactly.
    My question is whether or not the default settings in different Apple monitors should yield such different results.  I use Aperture on my Imac to edit colors on phots and videos.  I have nowe chenged my Air to sRGB and the colors are closer although the whites on the Air now have a blusih tint.  If I share my photos around to others, will the reddishness that is a problem on my Air also be on most other standard display profile settings?
    Thanks

    For me and my 17" iMac "Adobe RGB (1998)" from the preinstalled profiles has the richest color. Here is a great link to help you calibrate and set new profiles:

  • Factory Display Profile Trashed By Accident

    I please need your help. Today I thought I'd re-calibrate my display, did a little housekeeping and I accidentally trashed the iMac G5 factory icc profile. Now when I go to calibrate the display I get: The factory profile for the display could not be found. The display has gone from gorgeous to all washed-out.
    Does anyone know where to find this specific profile on the iMac G5 install disc or do I find it on the Tiger install disc? I have a great 3rd party program called Pacifist which allows one to extract files from the install discs without doing an archive and install; I just can't seem to find it. One more thing, I also need to know where to put this file back into the system, that's if it can be found and extracted. Any help would be greatly appreciated, thanks!
    All photography editing has unfortunately been suspended for now. I need that profile...
    Barb

    FWIW, I had to do an Archive and Install from the Tiger disc. Couldn't find the specific iMac profile anywhere using the 3rd party Pacifist application, although that app is excellent for extracting other files. It must have been buried somewhere deep within the system.
    So....the lesson learned is to be extremely careful when cleaning out your old display profiles or the calibrator for the display will no longer function. By all means, keep the iMac profile. I thought it was a profile I created, now I know it wasn't.
    It's nice to have things back to normal!

  • Missing PowerBook LCD Display Profile

    My screen looks odd today, so I checked the display profile in System Preferences. All that is available is Adobe RGB, Generic RGB, and sRGB. Isn't there supposed to be a LCD profile? I checked the Colosync folders in System, Library, etc, not there. Anyone know where can I get a copy?
    TIA,
    Jim

    Never mind...ran batch tasks with MainMenu, ran repair with Disk Utility, and restarted, and there it is: Color LCD.

  • Missing Display Profile

    I got this iBook in early September. It's been great except for one thing--the default display profile, Color LCD, goes missing and it reverts to Generic RGB profile in the display preferences. This causes the display to look faded with a bluish tint. The computer has 2 accounts--an admin and a standard account. When I log in under the admin account the display is ok and properly set to Color LCD in the display preferences. The problem seems to occur when I log in under the standard account. It will revert to Generic RGB and the Color LCD profile is not available in the display preferences. I switch back to the admin account and the same setting is in the display preferences--set to Generic RGB and Color LCD is not to be found. Restarting temporarily resolves the problem. I have repaired permissions, but this did not fix it.

    You might have to just reinstall the system.
    Otherwise I guess try the Calibrate?
    GOD Bless and Good luck.

  • Display profile for Cinema Display

    Hi there. I'm producing photographic images (for eventual print) and the print company is using Apple Cinema Displays their end (me: a Samsung SyncMaster 913V).
    There seems to be a great difference between what I see on my screen and what they see on theirs. My question is: would it help for me to install an Apple Cinema Display profile on my G4 to get a more accurate representation of their results? If so, where can I download this and to where?
    Many thanks for any help you can offer!

    Without using an optical calibration package from Gretag, Colorvision, etc you might get close but your still not going to get optimal results. Your eyes will constantly adjust to what they think is white, red, green and blue and tell your brain you have it right when in fact you dont.
    If your serious about getting this right then an optical measuring tool is required.

  • Is there a terminal command than can run to turn off all display profiles?

    The color display profiles are influencing/altering the RGB values that I am getting back from the apple color picker. Is there a way that I can toggle them all on and off?
    I am trying to use the color picker in FileMaker Pro 11 to sample colors from a photo that I am using as a background template. When I sample a color the color picker does not return the correct values. It keeps returning a darker value than it should. It's driving me nuts.
    I tried manually entering specific RGB values but the actual numbers don't stick, they changes when I close and reopen the object that I am applying the color to.

    The following will list the System frameworks but not necessarily every framework that you have installed by some third party application.

  • Issue with Display Profiles

    Hi eb,
    I have a problem with Display profiles. When 2 users are log in, my display profil switch to "Generic RGB" and I cannot change it to any other profil.
    When I restart and log in one user - everything is ok. When I log in second user display profile set to Generic RGB and issue start. When I log out one of them situation is same and issue persist.
    I tryed run Color Sync Utility > Profile First Aid , but no problems found.
    Had anybody same issue?

  • Default Display Profiles missing

    Reloaded OSX which solved some issues. Now the default display profiles are missing. The only ones listed are Adobe RGB 1998, sRGB Profile and Generic RGB. When I try to calibrate any of the three there message says The Factory Profile for the display could not be found.
    How can I get these back ?
    Please help....my daughters screen is very blue !!
