ColorSync - Display Profile Affect Importing?

Hi,
I hope someone can answer this question for me. When you import photos into iPhoto, does your current Display Profile (in System Preferences) have any affect on the ColorSync profile added to your photos? For example, if you imported one batch of photos, then changed your Display Profile, would photos imported from then on have a different ColorSync profile put into them? Or does it not matter?
I really want to start importing photos into iPhoto, but I'm very concerned that my current Display Profile will get embedded into every single photo.

It only adds a profile to a file if that file does not already contain one. If the file has a profile assigned by the camera iPhoto does not override the existing profile.
However, if you edit a file and then drag it to the Desktop it will contain the profile that the monitor is set to. I just ran a test on two files that were stripped of their profile, imported into iPhoto, edited and then dragged to the desktop. I had previously set my monitor to the Adobe RGB profile and the end image files contained the Adobe profile.
Bottom line is: the original file imported must not have a profile assigned and be edited before iPhoto will assign one (to the modified file).
At least that's what's happening on my present setup. You can check it out if you have any files without a profile. I used i iView MediaPro to strip the profile from the files for my tests. You can download and use it in the demo mode to run tests yourself. User the Action->Manage Color Profiles menu option.
NOTE: On another test just now, with *iPhoto's option to embed a profile unchecked*, iPhoto still embeds a profile into the modified versions. Very strange.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

  • Iphoto does not use the proper display profile

    Hello.
    I just bought a 20' Apple Cinema display and connected it to my Macbook. I have noticed a very strange behavior of iPhoto and Preview.
    I will first describe the expected (right behaviour).
    When I drag an image opened in Adobe LG or Aperture from the Macbook display to the Cinema display (or the opposite) after a very small delay the color of the image adapts to the color profile of the display where it was dragged. Which is the correct the behavior.
    With Preview or iPhoto this adaptation does not happen and the image is displayed with the right profile only on one of the 2 display. Besides being a very annoying issue, the very strange thing is how you can choose on which one of the displays the image gets displayed with the right display color profile:
    - With Preview, the display color profile used (for both displays) is selected based on which is the default display in ColorSync display settings.
    - With iPhoto, the display color profile used (for both displays) is selected based on which display the munu bar is (!!!). That is, if you want to have your image displayed with the right display profile on your cinema display, then you MUST have the menu bar on that display. If the menu bar is on the Macbook display the image on the cinema display will be displayed with the display profile of the Macbook display. Crazy!
    You can try all of the above remembering that after any change you need to quit and reopen iphoto or preview or ColorSync for the settings to apply.
    My question is: why neither iPhoto nor Preview act in the right way like Aperture or Adobe LG? Or at least, why iPhoto does not behave like Preview allowing me to choose where I want the menu bar without having this choice affecting the display color profile used to display my images?
    Thank you,
    Marco

  • Interface/Gamma issue - Display profiling

    If you profile/calibrate your display (with professional software) to Gamma L* - darkish, grey boxes appear in some application-windows. Never happend in Tiger so I figure it's a Leopard issue.*
    If you use Gamma 1.8, the Apple default, Photoshops windows (in my case) look perfekt. With Gamma 2.2 they're barely noticable (pretty much only if you know the boxes are there).
    All the other settings you can choose while profiling - like temperature, luminance, chromatic adaption, profile-type etc. don't influence windows in this way - but as soon as you change the gamma those boxes appear.
    I would very much like to know how you guys deal with it - do you profile your display to 1.8/2.2 (like a CRT) OR do you use L* and live with the boxes OR have you profiled your display properly/with L* but you don't have this nuisance? (!?)
    Any help/info would be greatly appreciated.

    *So here's what I think happens (+ my idea to solve the grey-boxes issue):*
    Some applications use the monitor-profile to draw their interface. Like Photoshop and Graphic Converter. (The only 2 I've installed, I'm sure some video-editing-applications, even players are concerned that's maybe the reason some people think it's 'random'). I think these apps do so to immediately can reflect a change in the profile, without restart.
    Now Mac OS X Leopard seems to not allow these applications to do so in certain parts of the interface. (Must be new, that's why there were no issues with Tiger) The window itself is drawn by the OS. That's the reason only elements like the text and buttons are affected.
    And the problem is that the OS uses its 'Generic RGB Profile.icc' which contains Gamma 1.8. So if you calibrate your display with Gamma L* (which you really should do and most profiling-software does by default) those grey boxes appear in said applications.
    The solution is easy. Replace the system-rgb-profile with one that supports L* - like the eciRGB profiles.
    To do so you have to rename the .icc file in finder but also edit the information inside (which can be done with the ColorSync Utility). Then copy it to the System/Library/ColorSync/Profiles folder.
    *After that the grey boxes dissapear and everything is back to normal.* There's some difference in the tabular data like the CMM and a chroma-entry, so you might want to re-write your display-profile just to make sure everything's alright.
    I haven't seen anything yet but could imagine that the rendering of webpages in safari might be affected. Or rather some webbrowsers' without colour management. (Just a theory, hopefully not...)
    *Problem 1:*
    Some Adobe apps can see that the current system-profile is identical to your working-space-rgb and reset your rgb-choice to the Generic RGB profile after a restart. (Without changing the 'Colormanagement SYNC'd icon/setting.) This probably could cause trouble if you export or open files.
    Solution:
    Use a different profile for your system than your Adobe-RGB setting. I used the 'L-Star RGB v2' for the system and the 'eciRGB v2' for Adobe. They're technically identical but for some reason Photoshop and esp. Illustrator now respect my choices and don't reset anything. Works fine for me.
    *Problem 2:*
    Besides the aforementioned chroma-entry in the Apple default profile (which loss shouldn't cause any issues) there's also the localisation information. Because the profile is named differently in different languages of OS X. I haven't found anything causing trouble (probably because if the profile isn't found it resets back to the english version by default).
    Solution:
    This would be easy if someone knows about a .icc file editor. If we could add those localised names from the Apple profile no application would ever know. I've only found hexadecimal editors but won't put something like that on my machine, especially since everything works fine.
    *I hope Apple comes up with a real solution soon, this seems like too much of a hack - considering the delicate nature of colour management.*
    *If you read this and know what I'm talking about and disagree or know any reasons why one would not want to do this - please speak up! I'm sure I'm not the only one who would like to know.*
    This is pretty much mirrored on the Adobe forums btw.

  • Display profile and scaled display

    I have a 13 inch mid 2014 macbook pro retina. Anyway, Im curious about the display profiles (i.e. color lcd, adobe, generic, and sRGB). Which is the default one? Will using one or the other help to keep my battery usage low? Same thing with the scaled resolution options. Will these help to lengthen battery life by a couple hours?
    Id like to find a way to make my macbook last longer on battery. Apple says they last about 9 hours but Ive been noticing its about 6 or 7 really, and thats with the brightness pretty low and with only safari open and watching a movie.
    Thanks for your help

    Color LCD is the correct choice. That is the profile made for the display at the factory.
    The only time you want to choose something else is if you have generated a customized profile using calibration hardware. Using a calibrator is usually important to photographers and designers doing color-critical work, but not necessary for users in general. The sRGB and Adobe RGB profiles are there for other uses (like photo editing) and must never be chosen for the monitor.
    The color profile has zero effect on battery life. Scaled resolution might, but I doubt it.
    The Apple Store page describes their battery rating: "The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The HD movie playback test measures battery life by playing back HD 720p content with display brightness set to 12 clicks from bottom or 75%...Battery life varies by use and configuration. "
    It is plausible to get less than 9 hours if certain factors are affecting the load on the computer. For example, if you've installed background processes that might use a little CPU all the time, like monitoring utilities, system customizers, or sometimes drivers for peripherals. Also, I am not sure whether the Apple test has Bluetooth on or off. In the Apple test, the movie is being watched in iTunes (using QuickTime), but if you are watching your movie through a different player like YouTube (which uses Flash) or Netflix (which uses Silverlight), the Flash and Silverlight technologies may drain the battery at a different rate than iTunes Quicktime.
    I think 6 or 7 hours is OK if you are using other applications like PowerPoint or Photoshop. Anything involving graphics is going to drain the battery faster than office apps or music.
    I have gotten very long battery life on trains and airplanes where there's no wifi, because I shut off wifi and Bluetooth and turn the brightness down when the cabin is dark. Under those conditions you might get at least 10 hours of battery if the CPU isn't under a significant load.

  • 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.

  • 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

  • Selecting color profile affects incorrect monitor

    I have a three monitor setup on a Mac Pro consisting of two samsung 254 BW's and a Dell U2711. All three are connected to an ATI 5870 with one samsung being on mini displayport and the other on DVI.
    The issue i'm seeing is that when I select a colour profile for either of the samsung's, the colour profile affects the one on mini display port only. So, selecting a different profile on the DVI connecte monitor doesn't change that monitor's profile BUT changes the other samsung monitor which is on mini display port.
    Anybody else seen this issue?

    I'm having exactly the same problem as well. Sometimes, after sleep, it has the correct Gamma 2.2. profile and sometimes it doesn't. As soon as I click on Displays, in the System Prefs, it changes back to what it should be namely Gamma 2.2.
    Very frustrating.
    I also have an external Apple Display connected and it also happens with this on random occasions!

  • Editing display profile

    Is there a way to actually edit the display profile in order to change the gamma? I calibrated my MacBook display manually, and I'm quite happy with it. The only issue is that it is slightly too dark.
    I would like to change only the gamma of the display profile without touching anything else. Is this possible?

    When I'm not sure if I'm going to like a profile, I just make two or three of them, all named slightly differently, since you can just switch between them in the Displays pref to try them out. When you settle on one and are sure you don't want the others, just throw them out of Computer/Library/ColorSync/Profiles.

  • When I use the new ColorSync icc Profile!

    Wwhen I use the new ColorSync icc Profile!
    the New Settings will be reset to Default Profile
    After Rebooting My Mac Mini 2010 with Mac OS X 10.6.7!
    Why? My LCD is Chimei 22sh-l with HDMI output.

    The Fact is that the Mac mini Bundled HDMI to DVI would made my ColorSync Profile to Default everytime I
    Reboot or logout my mac mini.
    Also, if you Rrealize the boot-up mac mini Superdrive DVD is noisy! You could just insert a DVD inside, then When you boot-up your Mac mini next time, the noise is Vanished ^^ & Happy
    So, Apple just accept its made Display Protocol for ColorSync to Adjust the Monitor Color, befroe I`ve done this,
    I  thought I have to buy a Apple Cinema Display or Macbook, then I can Get that kind of Benefits!
    But Hopefully, My problem is just solved & Happy .

  • User switch messes up Display Profiles

    I have a problem that's cropped up since I upgraded to Tiger.
    When I first startup or restart, when I open the Displays preferences I can go to the Color tab and select any of the Display Profiles I've created for either of my two monitors (Apple 17" 1705 CRT and ViewSonic VE150 LCD), or press the Calibrate button and the calibration application comes up. When I switch over to my other user account, I can do the same.
    But, once I switch back to user account #1, both screens get noticeably washed out, and when I select the Display prefs and go to Color it's defaulted to "Generic RGB Profile" for both monitors. I'm not able to select any of the other profiles in either window, and when I press Calibrate I get the error message "Can not calibrate the display - the factory profile for the display could not be found". User account #2 behaves the same way from that point, also. The only way I can restore functionality is to restart, at which point the Display color prefs work properly again, but only until I switch user accounts back and forth...then it "breaks" again.
    I've repaired permissions several times, run disk repairs, every maintenance thing I could think of but nothing fixes this problem. How can I get this straightened out?
    Thanks,
    Michael

    I came here looking for an answer to this exact problem (it was driving me nuts)... I only use fast user switching when I have visitors, and this is the first time I've needed the feature since upgrading to Tiger.
    Fortunately, I think I have found the solution after messing around for a bit (it worked for me anyway). I simply gave access to all of the system preferences (which it didn't have before) to my extra account. After doing that, when I switch back to primary account, the displays stay the way they should. I also found that this problem was affecting the sound on my computer as well. Everything seems to work fine now though.
    Hope that works for others as well...

  • Sharing custom display profiles between multiple users

    Hello,
    I'm brand new to Mountain Lion and I can't figure out how to share a custom display profile between multiple users on the same MBP. I'm a photographer and I have two users set up on my laptop - one personal and one for shooting. I'm using a Color Munki to calibrate my external monitor and the software creates a profile.
    Previously, I could go into my library, copy the profile and drag it into the colorsync folder for my other user, then switch to my other user and find that profile in system preferences/displays.
    I have no idea how to do this in Mountain Lion.

    Let me simplify this by refering to User A and User B to represent the two separate users I've created on my MBP.
    I've done some more digging and here's what I've found: In the Color Sync utility for User A my custom profile is in a user folder, represented by the name I gave the file when the profile was created. That's no problem
    When I switch to the User B, there are two profiles in the Color Sync Utility named "Display". The "Display" file was created at the same time my custom profile was created, however, the file names don't match and I don't know why there are two of them.
    I'm fairly certain that "Display" profile is the custom profile I want to use, but there's a problem coming down the road: what's going to happen when I profile my monitor again in 3 weeks.

  • Display profiles via a pull down menu from menu bar?

    I'm often switching my display profiles on my iBook-- depending on sunlight, lighting conditions, etc.
    Is there any software or Apple setting that would give me a pull down menu of my choices from the menu bar?
    Right now I have the monitors or whatever it is on my menu bar, but that requires multiple steps-- selecting Displays Preferences, waiting for it to come up, then clicking on the Color Tab, and finally picking one of the display profiles.
    I'd much rather have a one-step pull down menu. Anything like that?
    Also what does "Recent Items" mean in that menu?

    Open the AppleScript Utility in the /Applications/AppleScript/ folder and check the box to display the script menu. One of the choices in the script menu under ColorSync will enable you to change your display profile. If you know the names and paths of the profiles, additional scripts can be created that would change it in a single step. The lines of code needed are:
    tell application "ColorSyncScripting"
    run
    set display profile of display 1 to alias "path:to:profile"
    quit
    end

  • 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.
