Aperture Dual Monitor Color Profile Problem

I have 'discovered' an interesting problem when using my MBP with a Cintq tablet as a secondary monitor. The displayed colors agree very well in Aperture until I go to full screen and then the laptop monitor develops a greenish tint. I have tried all the different secondary display options, and in all cases where an image is displayed on both monitors the tint develops. It goes away as soon as full screen is exited. The Thunderbolt port is being used to feed the display to the Cintq (with a thunderbolt to DVI (?) adapter. I would guess that the laptop must grap the cintiq profile as soon as it goes to full screen.
In perusing the discussion group I see similar problems were reported in the past. It persists with the latewt MBP and thunderbolt, and latest build of Aperture.

I have no real answer except to say that on an older setup pre-Aperture I never did get the Cintiq 15 color well managed. I used the Cintiq mostly for palettes in Photoshop.

Aperture and dual monitor ICC profile problem

I am using an Epson Stylus Pro 3800 and run Aperture 2.1 from a MBP with a Cinema Display 23". I calibrated both displays (the 23" and the MBP display) with my ancient but working ColorVision Spyder, using OptiCal 3.7. I calibrated for a gamma of 2.2. and native white point. I check the results with various test images.
Here is the problem: the calibration produces a perfectly calibrated display, but when I open Aperture some color change is taking place, as if Aperture pulls in a wrong profile for the display (which then also leads to wrong colors in the prints): sometimes the photo which I have printed out before in perfect quality displays with either a nasty yellow cast or with totally oversaturated colors. I have used ColorSync utility to make the 23" the default display and I have also tried to simply close the MBP to work only with the 23", and sometimes either of these this did the trick. Most of the times, however, I get these color casts or oversaturation of the photos which I had worked on for a while and printed earlier with perfection.
I ran Disk Utility to Repair Disk Permissions (many Epson-related permissions were wrong, for example "Library/Printers/EPSON/InkjetPrinter/Libraries/UtilityCore.framework/Versions/ A/Resources/Icon8007.png", should be -rw-rw-r-- , they are -rwxrwxr-x ) and reinstalled the latest Epson driver for 10.5 repeatedly.
Even more surprising, at times the color of the full screen image can be off at the same time the thumbnail looks perfect! How is this possible? It seems as if thumbnail and full image use different display profiles. In addition, if I export the Master and display it in Lightroom or CS2 it looks perfectly fine and prints as expected. (I use the appropriate "canned" ICC profiles for the printer-paper combination).
The most surprising happens, however, when I drag the image from the 23" to the MBP: when the image is about half-way between the two displays (that is, one part is displayed on the 23", the other on the MBP scree) it suddenly changes from off-color or oversaturated to the correct color on the 23". If I then move the image up to the 23" again, the wrong display colors appear again.
I am at a loss: I have spent a lot of money on the gorgeous screen, the great printer, and Aperture (which is a great program), but I cannot get Aperture to print reliably, or rather, I cannot get Aperture to use the right display profile to display the image correctly in a reliable way.
I have read kbeat's color management blog and many entries on this blog here, but I have not found a solution. I appreciate your help.

Kai,Simon,
This is the problem i have been having.Colour profiling is correct,prints are rubbish.I run a fuji frontier
as well as epson printers.Anything from aperture is not what you see on screen.I am running aperture2.1.
Today we are removing 2.1 and doing a reinstall of 1.1 but not upgrading to 2 to test run prints.I have been looking for answers to this for sometime.
Simon,the problems we are have are very similar to you clients,photoshop fine,aperture not.I also have 20"external apple monitor attached which is used as the colour correcting monitor ( as the imac screen is not that good for criticl work ) I will post my findings here.
Simon, if you wish to investigate further,e-mail me,i am in leeds

Color profile problem after installing CS4

OK.
First, let me post these side-by-side comparisons:
As you can see in Image 1 (the "before," left-side photo in each comparison), the colors and overall appearance are distorted. I've read things about gamma but it's all confusing to me. This is surely a color profile problem, right? The transition among pixels that involve colors of yellow and gray is rocky, grainy, and the flat out color is just wrong. Now this color problem affects pictures when opened in both Photoshop 7.0 and the standard Windows Photo Viewer. Meaning, whenever I open pictures in both PS 7.0 and Windows Photo Viewer (my default viewer), this color problem totally messes up certain photos and really damages my ability to edit. I'm an avid photo editor and it's imperative I have proper color display so that I can accurately edit. Keep in mind that certain pictures do not take on this error. When a photo is generally brighter, the distortion is basically invisible. It's photos that are dark or have dark portions in them that display the distortion.
*Note: I took these before-and-after pictures with my camera, because screencapping would not work, since you all don't have the same color profile issue on your computer. That's the only way I can show you!
HOWEVER, when I open photos in another standard Windows application, "Microsoft Office Picture Manager," the color problem is magically erradicated altogether. It shows photos as I've been seeing them all along, until I installed CS4 about two weeks ago. Before installing CS4, everything was fine and I had been using Photoshop 7 for years and have never had a problem. I'm guessing CS4 messed something up. It had to have. Just FYI, I uninstalled CS4, hoping it would reverse the problem. But still, the color issue persists in PS 7 and in my regular Windows Photo Viewer.
Since images display their true form in Windows Office Picture Manager, I don't think I need to calibrate my screen. Or do I? I've read things about it, and to some people, it's not necessary. Right? Okay. I really hope someone can give some advice! Thank you!
P.S. Here's the original photo. On my screen, it looks distorted when opened in photoshop or opened w/the viewer. However, here on Firefox, it's fine.

You should try to familiarize yourself with the concepts of color management.
It's kind of too in-depth a subject to walk you through from a cold start here... There are a lot of good resources out there to help you get started. For example, in just a few seconds Google turned up this:
http://www.adobepress.com/articles/article.asp?p=1315593
The one thing to remember is this: There is NO quick solution, easy set of defaults, or direct answer to making your setup do what you want without your having to understand color management.
People may tell you to calibrate your monitors, or use a particular color profile as a default, or whatever, and they may have good, solid reasons for telling you those things, but if you don't attempt to get your mind around color management it will always seem as though something isn't working right, or is simply magic, which will be frustrating to you.
Here are some basic questions to ponder:
What image color profile is your image carrying?
Is your monitor a wide-gamut display and do you have a color profile set up for it? What kind of monitor is it?
What version of Windows are you running?
Do you know the difference between a color-managed app and one that is not color-managed?
Which of the apps you're using/showing above are color-managed?
What are your settings in Edit - Color Settings?
Take some time and do some research, get your head around the concepts, and it will all make more sense I promise you.

****yellowish color shift in LIGHTROOM: disabling monitor color profile in LR?

Hi all,
I would love to know if there is a way to ***disable the monitor (color) profile**** in LR.
WHY?
Cause all my pictures seems yellowish in LR, and not anywhere else (firefox, i.e, photoshop, xnview, etc...)
I solved the same problem in PHOTOSHOP, this way :
when loading images in photoshop, during starting up, I got this very message :
        " The monitor profile 'LG L245WP' appears to be defective. Please rerun your monitor calibration software. "
with two possible options :
        "Ignore profile" or "use anyway"
Then if I use "Ignore profile" everything is fine!
If I select "use anyway" --> Wrong, all my pictures are yellowish.
That's why I WOULD LOVE TO KNOW, pleaaaaaase if I can do the same in LR.
I personnally didn't find, or what else I should do ?! Knowing that I do not have a ...too expensive!... calibration tool , and my monitor is a LG, L245WP.
----> Thanx sooo much for your help.
       I would love to use LR, but this way I can't...

DdeGannes, Sean : thanx.
I went to my vista profil , added a profile in relation with my screen... but then which on should I select , between the several sRGB options :
- WCS profile : sRGB     a file named wsRBG.cdmp
or
- ICC profile : sRGB IEC 61966-2.1 ?
                                   ( of course I have many more... but....none of the others are sRGB profiles )
Then have you both a calibrator, and you both did all the color "chain" from CAMERA to PRINTER ?
I am asking.... cause all these adjustments + buying a calibrator seems tough to me to manage/achieve.
You know : I'm not a professional ...
To me, non - pro, it looks even more dangerous to do so than leaving evreything in default mode & presets...
Should I do something wrong...
NO?
Moreover I mean : this is odd that my computer , or/AND (?) screen ,
doesn't have a "default setting" which would be suitable in LR , at least which no colour shift !
( I just change my LG screen mode to 5600K etc... and still I have the same yellowish gap in LR )
Why would my color management just be wrong in LR or Photoshop ?
Doesn't this light something I miss to you both, maybe professionals?
If I read you fine, + the other website... everything is kind of automatic now in every softwares... even xnview, firefox, (not i.e.) etc...
so why just LR + photoshop, would be mistaken on my computer,
and Firefox, Xnview, CANON softwares, Painter, ... all show the right profile & colors ???? This is sooooooo weird....to me.
I mean I got the the point that my whole color management is unshure...
but it nevertheless it should BE THE SAME through all my softwares... NO ?
Isn't there a general ADOBE setting somewhere, that might be bugged instead?
I still think , according to that, that we are missing something.
Sorry to bother you with my thoughts....

ps/ Does really Photoshop detect the changes I would do directly on my screen ?
     Because when I switch from sRGB, to 6500 K , 9300K or user... on my screen,
     I STILL HAVE the PHOTOSHOP ERROR message :
     " The monitor profile 'LG L245WP' appears to be defective. Please rerun your monitor calibration software. "
      I mean PHOTSHOP doesn't seem to notice (give a damn) on any change I make !?
      As for the rest of my computer I never changed any COLOR PROFILE anywhere... So how do people do without a calibrator to use LR ?
      Is it possible at least?
      Is my screen (i thought so good) totally bugged, if none of my color profile is "ok" for photoshop & LR ?

How to solve the Embed Color Profile problem...

Hi Everyone,
This vijay from Chennai. I have one doubt for rectify the Embed color Profile problem, that's is how can i judges whether the file had Embed Color Profile or not. anyone solve this problem.
Thanks in Advance.
-yajiv

I used another profiles name, because I dont have the old one installed anymore, Youll have to be exact about the letters though.
And from a prepress-standpoint Id like to point out that removing the profile as opposed to »Convert to Profile« seems a peculiar practice, though of course Your reasons for doing so may be valid indeed.
You could try:
var myDocument = app.activeDocument;
if (myDocument.colorProfileName == "U.S. Web Coated (SWOP) v2") {
// =======================================================
var idassignProfile = stringIDToTypeID( "assignProfile" );
var desc2 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref1 = new ActionReference();

Monitor color profile, fast switch script

Hi everyone,
I often switch between two monitor color profile, the default one "LED Cinema Display" and the calibrated one, named with the date of calibration (ex:"22June2011").
Is there a way to fast switch between this two with a script, without entering in monitor preferences and move to color tab every time? Maybe set an icon on the menu bar... Or an icon on the dock...
Thanks,
Filippo

More important, the question is not about color management, is about scripting.
Otherwise we're just wasting words, that doesn't seem the right place to speak about profiling...
Do you want help or not? What you're asking has everything to do profiling and color management. You're going about the use of profiles for your monitor completely wrong.
Any profile is an image of how that, and only that device displays, captures or reproduces color. The only monitor profile that makes any difference is one you create. Since you're using i1Profiler, then you must be using an i1 Pro to profile the monitor.
The monitor profile you made with i1Profiler is the only one you should be using. It is an exact description of the white point, black point, gamut and color range of the monitor you are looking at. The canned profile has nothing to do with the monitor in front of you. It's a generic average that is just short of completely useless since it is not a direct description of the monitor you own. Forget the "LED Cinema Display" profile, or any other canned profile on the system.
I can only assume you're trying to simulate CMYK color in Photoshop. To do that, your start with the monitor profile you have. To create a meaningful CMYK simulation, you need to create your own inks file to use as your CMYK color space in Photoshop.

LR 2.5 and color profile problems with Samsung XL2370

Lightroom 2.5 / Windows XP3 / CS4 Photoshop / Samsung SyncMaster XL2370 LED monitor:
Changed monitor from Dell to Samsung's new LED SyncMaster XL2370. Updated Nvidia 7900GS card driver to latest version available.... resulting in a complete mixup of photo colors in Lightroom2.5 as well as CS4 Photoshop CR2(raw) and Tiff files; white becoming red, blue becoming green....., so really wrong!!! JPEG files are not affected.
When I change Color Settings(RGB) in CS4 Photoshop from ProphotoRGB or AdobeRGB1998 to Samsung monitor color profile, colors get at least more or less right.( I don't know how to do that in Lightroom?).
How can I resolve this situation? My complete photo archive is at stake obviously.
Thanks in advance for your help and support!!!

Thx Ian for your reply! Some more questions...
-Is it "normal" when unpacking/installing a new monitor and updating card drivers that it mixes up color profiles? Your solutions seem still pretty expensive!
-How come that when using other (non Adobe)tools (e.g Canon Zoombrowser EX) colors are OK?
-I know how to specify color profiles in CS4 Photoshop but how do you do that in Lightroom?

My monitor color profile changes after fast switching users, and then I cannot change it back in the prefs for display-color. Attempting to choose (restore) my chosen calibrated color profile does not work.
The only solution is restarting. Loging out and back in does not fix it, only a restart.

Dual monitors, ICC profiles, color management...problems

Problem:
An image displayed in Safari and then pulled off the web into Photoshop shifts colors noticeably. This is esp. apparent in a side-by-side comparison on the same monitor with the Safari window open next to the Photoshop file window…they look very different.
Possible clues?
When I drag an image in Photoshop from one monitor to the other it shifts color after I release the mouse. In my two-monitor setup one is a large LCD (that's the "main" one) and the other is a MacBook Pro laptop. Even though they both have ICC profiles the laptop is slightly more saturated than the LCD…and Photoshop seems to mirror this but exaggerate it. For example: I pull the same image pulled off the web into two separate Photoshop files and then I display one on each screen: the one on the laptop will be /much/ more saturated than the one on the LCD.
In the end, if I have 4 windows open of the exact same image (2 on each screen: one in Photoshop and one in Safari) I am looking at 4 differently colored images - with the Photoshop images appearing even more exaggeratedly different than anything.
Obviously I understand that the two monitors will never look identical, but Photoshop seems to be imposing some extra color management on my files that makes it impossible to use with my previously very helpful dual-monitor setup.
Specs:
- Dual monitor setup: both are calibrated using an i1Display 2 from x-rite and have their own different profiles (this is new as of this week)
- Mac OS 10.6.6 (w/all current updates)
- Photoshop CS3 10.0.1 (w/all current updates) :: Edit>Color Settings : set to North America General Purpose 2
Help?

Just read this entire thread and wanted to leave a few comments and qualifications, first a couple of FACTS for all to consider.
1) I am not "new" to color management - in fact I am quite experienced in color management at a commercial level since the days of film back when getting "accurate color" was actually difficult. At this point it should be easy if the involved software is working correctly and impossible if it is not.
2) I have the top of the line color management solution provided by one of the top players in the color management market and am using it properly as verified by their technicians.
3) I am running 10.6 on my main computers. Mac Pro, 2 27inch iMac sandy bridge quad cores, and am using mac cinema displays (new ones) on all of them.
Now the rant - I have been trying to run down this or a similar and related issue for over a year. If you happen to be experiencing the same issue as I am, which I will summarize as trying to get 2 displays to display anywhere near the same color (even identical monitors) do not bother upgrading to CS5 as I am using CS5 as well as a bunch of other tools (Aperture, LR, etc, etc) - this is BROKEN and all I can get from any of the vendors involved is finger pointing from one to the other. Each of them wants to blame the other vendor for not doing something correctly but NONE of them can actually give me any details as to what exactly is the problem.
At this point in time I am holding the color management vendor I use to create the profiles responsible - the reason that I am doing that has nothing to do with what exactly the technical problem is. It s purely because they claim that the product is compatible with OS 10.6 and they claim that their software does EXACTLY what I want = mach two monitors. Now we all know that different monitors have slightly different gamuts but at the end of the day if two identical colors fall within the gamut of both monitors they should display the same. They don't. I have worked with my color management vendor for 6 months on this, they agree that it is not working properly, they blame apple but they cannot tell me exactly what the issue is.
If a company advertises and sells a product they claim to be compatible with a particular brand and version of hardware and software and they claim that it will manage color consistency across multiple monitors (even on differing machines) then I believe they are ultimately accountable for ensuring it actually works and resolving the issue - whatever it is, if it fails to function properly.

Display Calibration Creates Color Profile Problems.

I haven't received any response out of the MBP Display forum and I thought you guys might have better insight anyway because you are dealing with color calibration more often. Here it is:
I used colorsync utility to calibrate my monitor, hoping it would at least get the colors more accurate than they are with the "Color LCD" profile. The Color LCD profile has a bad yellow tinge to it. I went through the process 4 times so I would be able to choose the best profile out of the 4. (Now I can't delete the extra profiles but I guess that is a different topic...) The color accuracy and the gray-tone is MUCH better BUT I have a slight (understatement) saturation problem.
My problem is after using Color Sync, ALL of my REDS are oversaturated and blown out. There is a problem with the blues and greens as well but it isn't as bad. Of course, they look fine in non color managed applications (ie FireFox) but everything else makes my photos look horrible. Even the RAW files straight out of the camera look blown out.
I had, at first edited these files on a PC so they always looked fine but now that I have switched to Mac I have noticed how oversaturated they are in all of its color managed applications. (Safari, preview, and even the desktop.) I thought perhaps that I had just pumped up the contrast and saturation too high on the PC and the color profile was now creating a problem because the color was set for an un-profiled file. BUT after viewing the unaltered .NEF's straight out of my camera, they too are oversaturated.
Now, I have some wallpapers I had downloaded from the web that look the same as before. It is just MY OWN photographs that are oversaturated. Obviously I have chosen the wrong color profile or something is wrong with my workflow. The wallpaper that looks the same doesn't have a profile assigned it when I view-info. It just labels the color space as RGB. All my photos that have problems, have a color profile assigned. I am using sRGB as recommended. There are a few still using Adobe RGB (which is what my camera defaults to) and they have the same oversaturation problem.
Aperture is set to export with an sRGB profile and CS2 uses sRGB as well.
Any advice? What monitor and color management profile's are you guys using?
I can't tell what is right anymore. What should I edit my photos to look good in? The only MONITOR profile that doesn't blow them out is Adobe/Apple RGB, Color LCD, and a few of the other default installed profiles.
I've got a bad case of color vertigo!

sorry uberfoto, did not get what MBP meant at first.
what Jan says about color calibration tool is right....and start again from the RAW.....
i am photographer in the advertisement, reportage, portraits and landscape.
my problem was to get the thinks printed as I saw them on the screen.
here what I have to say on that (part of another discussion):
".... Sorry, but no AppleTFT Display comes close to a hardware calibrated display. Maybe they are semi-professional. I do not say this to insult Apple, ore somebody else, but i say this to sway out the illusion of , " if I just spend more money on the calibration tool and software, I´ll have better prints". It´s just not possible, because the display cant show what is there. A Apple CRT Studio Display is far better in this. I you want to have a flat-screen TFT Display to bring good results, you have to choose one that is able to be hardware calibrated and has a higher lookup table (EIZO, LaCie, QuatoGrafics......)
I use use one professional EIZO CG21" and one semi-prof. EIZO FlexScanL985EX(21") and the diffrence is important between the two.
But i need only one to be Print Proof ready.
Before i was always afraid when i gave the picture file to my client, because of what my pictures look like once it is printed. Now the outcome is right or differs only very little from what I saw on the screen. my calibration tool is EYE ONE. "..
BUT your main problem is how it looks in the web.
my thoughts and suggestion on this:
1. most people see the web on PC Display. those use a gamma of 2.2
(apple = 1.8) so pictures appear more blue with more contrast. this setting is made to hide the low ability of the system and display to show colors as they are and give and give crispy impression. So you will have to consider this when you prepare the pictures for the web. therefor the standard calibration of your MBP is best for your needs. ( for printing the Display has to be set on 5.600 kelvin ,that would be to warm 4 the wwweb).
2.
a) In the beginning I use Aperture 1.5 (or Lightroom) to select and prepare the pictures as I like them.
b) then I export them in 8 bit/300 dpi in the size they will be used as PSD or TIFF.
c) I will then open them in Photoshop (color-settings=web /internet) make the cleaning and so on.( 4 the web I always increase the saturation because sRGB and JPG will throw away lots of colors).
d) AND NOW "save for the web ". This is definitely the best tool to prepare pictures for the web. on the right upper part of the window there is a flash-open menu where you may choose to see the colors like in windows or macintosh system.
and on the lower right of the application-window there is a roll-down menu where you may preview the results in different browsers of your choice.
It is here where you can produce amazing high Q pictures 4 the web under 100 kb.
Hope this may help.
good luck,

Dual monitor color issue - oversaturated image in CS4

Hi, I wonder if you can help. I found people having similar issues, but never seen an actual answer, so your input would be greatly appreciated.
My set-up:
MacBook Pro Dual Core intel based 15.4 2.6GHz running OS X 10.5.6 - also my primary display
HP LP2475- secondary display
CS4
Both monitors were calibrated using X-rite Eye-one LT (each with a separate profile)
I've tried calibrating each monitor 3 times and still get the proble,
My problem:
Running in dual monitor mode in bridge or safari/firefox- no problems at all: almost consistent colour between both monitors.
When I open the images in Photoshop CS4, they look fine on my MacBook screen, but when I drag them over to the HP the color is grossly oversaturated - especially in the red. What am I doing wrong? (in fact on the HP monitor, the color looks perfect in bridge but super insanely saturated in CS4)
Does anyone have a clue on how I can fix this?
Thanks!

You say your running 10.5.6? Why haven't you updated to 10.5.8?
FWIW, I never had color issues under 10.5.X, however I have since upgrade to 10.6.

Dual-monitor color management?

So I've got a dual-monitor setup running OS 10.7 on a Mac Pro, and color management in Bridge CS5.1 on my second screen is a mess. Both monitors have been individually calibrated with a Pantone Huey Pro (not perfect, but generally pretty consistent across screens).
Viewing an image in Bridge on my first screen, I have no problem. But the same image, when viewed on my second screen, appears heavily oversaturated. When I open the image in Photoshop or Preview, the color is accurate and is consistent across both screens. The below image illustrates the problem: the colors shown correctly in Photoshop (foreground) and incorrectly in Bridge (background). The Creative Suite color settings in Bridge show the settings as "synchronized" with the "North American General Purpose 2" default.
I'm sort of out of my depth here when it comes to color management. Do I have something set wrong? Is this a Lion-related bug? Any help would be appreciated.

The way I have it set up is this: I have two synchronized windows, one on each of my two displays. In one I have a content panel, metadata, collections, etc. In the second window I just have a preview panel, supplying me with a full-screen (almost) preview of any thumbnail I select from the content panel in the other window.
Content (assuming thumbnails as well) panel preview on one display and the Preview panel preview on the other display are both being generated by one application and that is Bridge. Like I said above, I don't think, in fact I'm almost certain this is impossible for Bridge to pull off because of the dual matrices (mathematical formulas) written into each custom display profile that occupy the same video chip to calculate and control hue/saturation appearance in color managed images. Think of the complexity involved. Now Adobe is known for creating workflow miracles with their programming but I doubt they'ld be able to pull that off with Bridge.
Photoshop can pull this off having one image on one display and dragging to the other where it makes the adjustment on the fly. I've seen the quick shift that occurs doing this. But I don't think Bridge can do this because of it's caching structure. I hope an Adobe employee chimes in to correct me.
Now this dovetails into your mentioning forcing a display into the sRGB space during calibration and profiling of each display. This is not what happens doing a hardware calibration. I'm assuming you pick your target Luminance (120 cd/m2 +/-), Gamma (2.2. gamma-usually native) and Color Temp (6500K). It doesn't matter if you did anyway, but what the hardware calibrator does is measure each display's RGB colorant and density range and write the data into the final profile that allows applications like Colorsync Utility to display a 3D gamut model and color managed applications like Photoshop to show colors as intended.
Your display may be close to sRGB but never exact to it because sRGB is a synthetic (made up) color space. Your display has physical anomalies that must be measured and written into the profile to properly display the intended appearance of color referencing the CIELAB color space which is based on human vision. Everything about computerized color in a color managed workflow is based on mapping color to display properly according to gamut size. A computer is a dumb machine and has to be told everything using math. You actually do have to draw it a map to follow.
Bridge's Preview pane looking different may be either referencing the other display profile or is stuck referencing the other and what's happening is the equivalent of Assigning one of the display profiles to the Preview like you can do to an image in Photoshop. Try it. Take your image and convert to one of your display profiles and assign the other display profile to it. Check if you see a slight shift. If Bridge's main Preview pane is stuck showing pixels mapped to (synthetic) sRGB then the same assigning of the display profile effect takes place.
And/or the thumbnails aren't color managed and the Preview pane is and maybe a bit of the above is compounding things. If you aren't confused now can you imagine trying to mathematically write the thumbnail previews on one display and the main Preview on the other both controlled by one application on top of caching and managing a large image database?
Keep the Preview pane and Content pane on one display. Edit your images in Photoshop/ACR/Lightroom on the primary display.
The Color Settings where you select North American Prepress...Web...General Purpose...etc. only applies to how images are handled and previewed that don't have an embedded profile. Are your jpeg images embedded with a profile? If so then this is not the issue. This doesn't apply to Raw captures because their previews are generated by the default Adobe Camera Raw settings.
Omke, no more Version Cue? That's welcome news!

Print driver/color profile problems after 2.0 update

Since I updated to the latest version of aperture 2 I have had problems with printing on my canon 5200R printer. The coloring is way off, as if aperture does not seem to recognize the canon print drivers or color profiles. I have read about printing from another program but was so happy with color quality using aperture 1.5, is there a fix for the current problem?

Bump.

Aperture 3 embedded color profile bug still unsolved (worked in Ap 2)

RE: Aperture 3.x cannot display images with certain color profiles embedded. This bug was reported
on March 11, but is still unsolved and basically makes Aperture 3 unusable for my large collection
of scanned slides which have a special color profile embedded. Viewer and sometimes Browser turns
either black or go haywire.
What is it about:
When you scan slides with a scanner, you can generate a special color profile so that the image
looks good and you can then embed this profile in the scanned tiff and jpeg images. Most pro applications honor the embedded profile and display the image correctly. In our case, we
generated a special profile named Nikon-LS5000 (it was tested for correctness!):
1) It worked fine in Aperture 2.x
2) It never worked in Aperture 3.x
3) It does not depend on the Operating System (i.e, the bug manifests itself in 10.6.2, 10.6.3 and now in 10.6.4)
4) It is no question of a special Mac Model (the bug shows on iMacs, ibook profs, and iMacs 2010)
5) It is irrelevant whether you start Aperture 3 in 32-bit or 64-bit mode
6) It shows with jpegs or tiffs, no matter
7) Preview.app or Photoshop CS4 display the images correctly!
8) If one changes the embedded profile via PS CS4 to sRGB or ProPhoto, Aperture 3 works (but the
image then has radically different colors - so no solution!)
9) The conclusion is that something affecting the processing of (some?) embedded color profiles has radically changed from Aperture 2 to Aperture 3.
I put a few jpegs with embedded color profiles and screenshots of how Aperture 3 behaves on the Picasa web:
http://picasaweb.google.com/114939413495021552399/TestapertureBilder#
you are invited to download the jpeg- images and retry in your ownAperture 3 Library.
Maybe together we can find out what causes this bug which is very annoying for any
serious photographer.

I have put the test material on another server - you can download a
zipped folder (Aperture3profilebug.zip) of all test images AND the color profile from
https://depot.uni-konstanz.de/get/txau69
with any browser. (The problem was that the Picasa Software seems to strip the color profiles from
the test images, so I had to put them on another server. It will remain there until July 1).

.Mac Gallery Color Profile Problems

Love the new features in aperture. I was really excited about the .Mac gallery integration as when I send clients photos i normally just put them on a web directory as a zip file with now pretty gallery at all. I was excited to learn i could publish the full resolution versions to .Mac and it would make a zip file for the client to download. this is great!
The Problem:
1. The downloaded images are in 8bit Adobe RGB. No matter the settings.
What I have observed.
I've made a few galleries to avoid refresh problems.
At first i thought it was because my .psd's and some raw images were in the Adobe RGB color space.
I do edit in 16 bit Adobe RGB in photoshop. One of things that i looove about aperture is i can edit in Adobe RGB and then use Aperture to do color management and bit depths/file types and so on.
I tried making sure all images published were converted to sRGB thinking that it just took the default color space of the original image. This did NOT fix the problem.
Problem occurs with both allow downloading of "Optomized Image" and "Actual Size" settings
any final output is usually 8bit sRGB for anything. Macs are Profile aware but most clients have crummy PC's so images won't display or print properly. It would be awesome if we hat a little bit more control over what is posted for the "download" like pick a setting from the output presets just like you can with the HTML web galleries and such. The preview images for the gallery, (what you see in the browser) are in the sRGB color space. But the downloaded images using the download feature are always in 8bit Adobe RGB no matter what the source color space is in.
Let me know if anyone else is experiencing the same thing or if they know of a fix.

I have the same problem. Most of images are in aRGB and when they are uploaded to the Web Gallery there's no way to convert them to sRGB. The images on the gallery look washed out on other people's PCs.
Does anyone know a fix for this problem?
