Color difference once loaded in browser, color profile or something?

Hello, I haven't noticed this before, but this pic is particularly dark and its giving me trouble.
It was a raw NEF, then loaded into Photoshop, tweaked and saved as a JPEG using SaveForWeb.
The picture looks as I want it when viewed in an image browser, but upon loading it into any web browser the blacks get a lot darker and a lot of detail is lost.
What am I doing wrong? Any thoughts?
Cheers,
Chris

The image from the original post with sRGB assigned seems to display pretty much OK in Safari and FireFox for me.
this thread is only in beginners because that was the only option available.

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,

Bad color profiles on B8850

posted in another forum but thought I'd try here before I lose my mind trying to figure this out...
I think perhaps my color profiles are bad? Here's the situation:
1) printed a color wheel image on plain paper to test what colors I'm having problems with, and everything looked fine.
2) printed the same color wheel on photo paper and the oranges are just dead, really grey looking, but the rest of the colors are fine.
So, seems like the question is why are my photos not printing correctly on photo paper but do on plain paper? Any ideas or suggestions? Bad color profiles or something for the HP Photo Paper?
I'm losing my mind trying to figure this out. Any ideas are greatly appreciated.
cheers,
Aaron

Every type of paper accepts ink a little differently. If there is a setting that matches that particular paper right in the driver preferences available, I would try that. However, if that is what you are using, then try a different selection, or go into the color management tab (depending on operating system, drivers installed basic versus full) and adjust colors that way to improve the output on that media.
This might offer some additional help:

How do I load a color profile onto my CS3?

My printer has requested that I work in CYMK, GRACol2006_coated1v2.icc color setting. I can't find it on my list of profiles. My printer has sent me the file. How do I get it into my pull down list?
Thanks in advance.

Profiles need to be added via Windows's color management. Put the profile in C:\Windows\System32\Spool\Driver\Color along where the other profiles are and it should show up as a printer profile. You can also put them in Adobe's color folder C:\Program Files\Common Files\Adobe\Color\Profiles.

Converting RGB to DNG without affecting color profiles

Hi guys
I'm working with the DNG SDK in C++ for some time now. I need to be able to take a raw RGB (not camera raw) and convert it into a dng file. After playing arond with it for a few days, I realized creating the camera profile drastically affects the resulting dng image.
I can't seem to produce a dng file that was identical to the input source. My picture appears very washed out and I end up using the adobe color profiler to try to bring the image back close to it's original color.
I'm trying to find a way to produce dng files without the need to affect the colors in any way, the resulting picture should be bit identical to that of the raw RGB input file.
I'm not even sure if I can do this considering the usage of the dng format.
UPDATE
I've realized that my program is loading the RGB buffer into the fData of the stage3 image object. I have a feeling I need stages1 and 2 but i'm unsure if I need to and if so, then i will probaby need a source DNG to produce those stage1 and stage2 unless I can get stage1 or 2 from stage 3 (appears it works vice versa).
I'm able to do the reverse (DNG to RGB raw) by extracting the buffer from the stage3 render. but in this case, all the metadata has been filled in by the input DNG. However, going from RGB to DNG, I don't have the metadata to fill into stage 1 and 2.

My understanding of the JPG is only middling. I thought I understood that it uses anchor pixels and either a translation table of some sort or difference mapping, using 8 bits per piece of information.
If that were the case, surely changing the translation from CMYK to RGB would be fairly simple.
In this case, the usage is Ebay and they only accept JPG, PNG (and maybe BMP and GIF, I didn't look that closely), but require RGB. I was actually quite surprised to find that JPG allows CMYK since, as you say, anyone dealing with CMYK is going to be dealing with commercial printing and few people who deal with commercial printing would play around with JPG.
I always stick to TIFF or PSD for workflow, but JPG is popular for a reason - when it comes to web, JPG is the only format that can deliver manageable file sizes with full-screen or "large" images for web. Our top level banner photo is 2590x692 and needs to be under 400kb for sane download speeds. PNG couldn't touch that. Even with the aforementioned 1800x1200, PNG is nearly 2mb, while I can maintain very decent quality with a 500kb file with JPG that works well for 'zoom in' type usage.
So there's no way around JPG. It's just annoying that the first person to touch a random selection of the pics was primarily an Illustrator user and saved *some* of the pics in CMYK mode.
It's like that old story about the farmer who didn't want anyone to steal his watermelons, so he cleverly posted a sign "None of these watermelons are poisoned", only to find a note the next day saying "Now, One of these watermelons is...".
Far more work to fix 'some' of the images compared to just doing it right the first time.
But then again, for workers like that, if you can't trust them with an easy job, you could hardly trust them with more complicated jobs...

Embedded Color Profile is Lost When Content is Published to Web or Dragging Image Window on Desktop

Hello, Everyone. I have a question that I have struggled to crack on my own to no avail. I hope someone here can help.
I am trying to publish some images to the web using color corrected monitors, RAW format, and a color checker passport to create a perfeect color profile. Here are the technical details and my workflow.
Camera: Canon Rebel EOS Xsi
Format: RAW + L
Color Space: sRGB
Color Checker: X-Rite ColorChecker Passport
Monitor Calibrator: Spyder4 Pro, fully updated software
Computer: Lenovo T420 ThinkPad
Second monitor: Samsung LED SyncMaster SA350 (NVIDIA)
Photoshop: v12.1 x64 (CS5.5)
Photoshop Color Settings: Custom North America Web/Internet
RGB: sRGB IEC61966-2.1
CMYK: U.S. Web Coated (SWOP) v2
Gray: Gray GAmma 2.2
Spot: Dot Grain 20%
Policies
RGB: Preserve Embedded Profiles
CMYK: Preserve Embedded Profiles
Gray: Preserve Embedded Profiles
After importing the image into Photoshop, I make sure the RAW space is set to sRGB IEC6 1966-2.1
Use the eyedropper to select a neutral color one step away from pure white on the RAW image of the color checker, create and set the custom white balance.
set the white balance
Export the image as a DNG
Load the DNG into the X-Rite ColorChecker Passport software to create a color profile
Back to Photoshop
Open the RAW file
Set the white balance to the custom profile created above
Set the color profile created with X-Rite
Open the color-corrected image in Photoshop (see color setting above)
Save as JPEG
Publish
First, everything seems to go great throughout this entire process, until I see the image on the Web: LINK. Once published, the image has a very noticible golden-yellow tint to it. The color-corrected image looks great on both color-calibrated monitors, in RAW and JPEG. Absolutely perfect. After noticing the ugly yellow tint in the image I posted to the Web, however, I became aware of a couple more weird things.
1) When the JPEG was open in Photoshop and I moved the window that contained the image around on my second monitor, the image immediately took on that golden-yellow tint: you can see a screen shot of the color corrected image on my Samsung (bottom) and the yellow version of the same image created when I drag the window around on the Samsung (top) HERE.
2) When opening the X-Rite software, I got a warning saying that the laptop monitor had been calibrated, but that the Samsung had not. I got this error even if I calibrated the Samsung monitor right before using X-Rite. Also, the monitor is definitely calibrated, because the images look great, and the colors match what I see on the laptop.
3) Recently, I noticed that when waking my computer from sleep, the Samsung monitor no longer holds its Datacolor (Spyder4) calibration.
I thought the problem I was having might be due to the monitor, for the reasons stated above. However, I later noticed that when I open the color-corrected JPEG with the default Windows image viewer, it retains the color correction settings. The image looks fantastic, and doesn't lose it's color profile when I drag the window around. Also, there seems to be less color loss in the Word documents and PDFs I included this image in: LINK.
I checked this with several more images, and the results are the exact same. I scoured the Web as best I could, but my problem seems to be pretty unique. Does anyone have an idea what might be causing this?
Thank you!

Thank you, twenty_one, for taking the time to read my post and put up a reply. I am going to rebuild my question and post it again here. But first, to answer some of your points:
1. A raw file has no color space, until it's opened into one in the raw converter. So this is controlled in ACR, not the camera.
I just wanted to be as thorough as possible. One of the steps I took was to set the Color Space setting in my camera to sRGB:
2. White balance has no bearing whatsoever on camera profiles. A profile is not for white balancing, it's to account for the spectral distribution of the light, which is something else. You make the profile and assign it in ACR, then you white balance for processing.
I know. I wasn't talking about white balance in my camera. I set the white balance here:
I grabbed the color for setting the WB here:
3. If you get a message about monitor calibration upon opening the camera calibration software, something is seriously confused. The two have nothing to do with each other. No relation whatsoever.
Camera calibration software?
4. A corrupted monitor profile will only show up in Photoshop and other color managed software. Other applications that are not color managed will not use the profile and are not affected. So find out which apps are and which aren't before drawing any conclusions.
Agreed. That's partly what I am trying to get help with.
5. Your links don't work, and in any case clicking on links is something most people including myself dislike. It's much better to insert screenshots in the post, by using the camera icon in the reply box.
I'm new to this forum, so this is helpful to know. This image shows the color-corrected image (bottom) on my Samsung. It looks exactly the same in the same window on my laptop monitor. When I move that window around on my Samsung screen, it turns gold (top). The image, when posted to the web, looks *similar* to that gold color.
So let's say I only use Photoshop on my laptop, which is not displaying any colors. Do you think the golden hue problem will go away?

Leopard forgets color profiles when waking from sleep on MBP Santa Rosa

I have a 15" MBP Santa Rosa with a 22" Samsung external monitor. I performed a clean (erase and) install on my machine. Upon waking from sleep, the computer seems to have forgotten the color profiles loaded for the displays. To correct this, I open system preferences and then the display option. As soon as the display options are shown on the window, my MBP loads the correct profile. This has happened for both displays, though far more frequently on the external display. The profile for my Samsung was created using color calibration hardware/software but the MBP display is running the stock profile from Leopard.
Any thoughts? Has anyone else experienced this?

same issue here. also had it in tiger, but much more frequently in leopard. seems to be whenever my display wakes from sleep.
MBP 2.4 GHz SR purchased 6/07. also driving samsung 245bw external display (which has never been affected, unless perhaps my calibrated and default profiles aren't different enough for me to notice--the difference is severe on my built-in display).

Bad ramifications of color profile used in previews

It seems that Aperture's choice of color profile for its previews has some rather wide implications. In a RAW workflow, previews are assigned an Adobe RGB profile. In a JPG workflow, previews aren't generated at all at first (which makes sense - no need to create a JPG from a JPG), but they are created once you edit a photo. Then once again, the preview is assigned an Adobe RGB profile, irrespective of the color profile of the original photo. This all kind of makes sense. Presumably, Adobe RGB is the same as, or close to, the color profile Aperure uses internally.
The problem comes when photos are "shared". With the Aperture preference set to "Share previews with iLife and iWork", Aperture generates an XML file that can be used by external programs. This XML file points the external program at the previews (or the original in the case of an unedited JPG). Then photos can be picked up in various places:
* In mail.app via the Photo Browser.
* In any app via the Media section in Finder.
* On an Apple TV via the "Choose photos to share" option in iTunes.
BUT - all these photos (with the exception of an unedited JPG) will ALWAYS have an Adobe RGB profile. This is generally not good, since the photos will display badly in any app that isn't color managed. Unfortunately, this seems to apply to Apple TV. Photos there have the typically subdued look of Adobe RGB when not color managed. The situation actually gets worse with JPGs. An unedited JPG which originally had an sRGB profile will display fine, but as soon as you edit that photo in Aperture, it willl display badly because now iTunes/Apple TV is working with an Adobe RGB profile. I've done tests and it's painfully obvious.
Anyone else come across this? I'm not sure what can be done. Maybe having an option to generate proviews using sRGB would be good, but that might involve too much processing in Aperture when it's continually generating previews as you edit.
Thoughts appreciated!

The export settings don't have any effect on the problem, unfortunately. What preference are you referring to? Do you mean the Import "tab" in Aperture prefs? That just governs what Aperture uses for its initial preview. it will now, by default, use the preview that is embedded in every RAW file to speed up processing. As soon as you look at the photo, even without editing it, it will then generate its own JPG preview (with Adobe RGB profile).
I haven't received any other feedback about this problem anywhere, which is surprising to me. I think I can only post the problem through Apple feedback, and hope for the best. It seems that, in the meantime, the only course of action is to export everything you need to display properly on an AppleTV, and re-import those JPGs into Aperture (or iPhoto) so they can be displayed via iTunes. A royal pain!

Change Default Color Profile in New Image Document ?

I've looked and looked, and even Googled. Anyone know how to change the default color profile when you start a New image file? In CS5 mine defaults to sRGB (Under the Advanced drop down) but my CS6 is ProPhoto RGB which means I have to change it manually nearly every time I paste an image copied via right click in a web browser.

I think it the same on windows. If I copy things to the clipboard with Photoshop that the document profile seem to be used there when I do a paste there are no color issues. However if I use Prtscn or Alt+PrtScn to capture screen content. I'll see that the colors are wrong when I paste the clipboard into a new document if my default color space is not sRGB. Then I need to assign sRGB to the document to correct the colors.
If I paste a screen capture into the current document the color can be very off and I will not get a prompt on the color mismatch. Therefore I don't think a screen capture has any profile associated with it. And of course the screen has a much lower resolution then the images I edit. So there is also a big size difference. Here is one scaled to 100% zoom after the paste. You can see both the color and resolution difference. This capture was assigned to sRGB so you will see what the screen looks like after the paste and zoom to 100%.

How do I get a custom color profile into a PDF?

I have a client who provided a custom color profile for a CMYK file.
I worked on Photoshop CS5.1 images and made sure the profile is embedded.
I placed these Photoshop images into an Illustrator CS5.1 template and made sure the profile is embedded.
I need to create a hires PDF with the Press Quality settings from the Illustrator file.
I have been doing a Save As to PDF from Illustrator, which seems to work.
OK, that's when my troubles start.... When I go into Acrobat Pro X v10.0.0 nothing indicates my profile is there.
I even have the profile loaded into Acrobat.
The client seems to want the Paper Simulation to show their profile, but the profile does not even come up in the list when I look for it. It seems to default to RGB even though this is a CMYK file.
I messed this up once already, and I need to get it right this time.
The client is in Germany and they sound very angry when they don't get the proper files.
Help!

IWeb 08 screws my photos color profile

Anyone has this problem with the new iWeb 08?
I installed the new version, ran it without any problems, did some rearranging of my site, created a new page etc.. And then published the whole site all over again.
But now, all my images are tagged with the sRGB profile instead of the profile that was in the images.. now all my images have become very saturated and dark. The thumbnails are fine, but when you click in to see the photos in slideshow or not, the images are loaded and it looks horrible.
I've went into my iDisk to check the images and found that all my photos are tagged with the sRGB profile instead of my normal AdobeRGB profile or Nikon sRGB profile or no profile...
ARGH!!!!

iWEB 08 is a fully color confused application, whilst iPhoto is only partly color confused.
The following applies when dragging images from iPhoto library, with the "Optimize Images on Import" option on. According to the manual, this option only changes the size, but I would not be surprised if it changes something else also. Then after, exporting from iWEB to files on the hard drive.
Having spent 8 hours analyzing the problem, I am beginning to understand what is happening but certainly not WHY???
iWEB appear to convert the images 2 times (when importing and when exporting I wonder), both times incorrectly, and to top it off, it exports images without a color profile BUT with the EXIF data of the original, which at this point is incorrect. HOWEVER, it appears that thumbnails are only converted incorrectly once, adding to the confusion.
Before going into some remedies let me answer the question: What color space etc. is "correct" for the WEB?
There are three rules to publishing photos on the WEB (files for download is a different story):
a) Image, including thumbnails should be in sRGB color space (Otherwise it will NOT display correctly on MicroSoft systems, where browsers happily ignores color profiles and sRGB is ASSUMED for all images)
b) There should be an sRGB color profile in the image file, including thumbnails (Otherwise it will NOT display correctly on MacOS, where browsers assume AppleRGB, but will happily adjust to any color profile)
c) Discard unnecessary information in the file to reduce size, such as EXIF information, thumbnails etc (optional rule)
Having said that, you may ask yourself, who do that? Well to tell the truth, not many. A quick check on Apples website reveals that there is a mix of color "strategies". For instance, the pictures demonstrating the cool features of iLife08, appear to be in sRGB but without color profile. Thus, they will be displayed correctly on a MicroSoft system but not on a Mac.
Well, back to iWEB - To try to fix the color problem, do one or both of the following:
1) Keep calling Apple Cupertino until they fix the problem (really, I am not joking, I am tired)
2) Convert images after they have been exported. This seems to work also, almost. However, converting a pictures color space is not exactly reversible, thus result is not perfect. Use for instance Photoshop CS1 or later (make sure color settings is such that there are no conversions when you open files and use the colorimetric conversion option in advanced settings) and:
a) Open picture
b) Assign AppleRGB profile
c) Convert to sRGB
d) Assign the original profile (usually sRGB or AdobeRGB or the cameras RGB)
e) Convert to sRGB
f) Save (with option: include color profile)
File is now about 2 times the original
g) Open graphics converter
h) Choose convert...
i) Choose file(s), hold Cmd-key and choose remove resources (which does not remove the color profile)
File is now ok for publishing on the WEB
TIP, if it seems like a daunting task to manually convert all of the exported images (and do not forget the thumbnails), make an Action-script in Photoshop, then use the Batch feature with sub-folders etc .... . Also the graphics converter operation can be applied to include subfolders. I did this, and it works ok, but be sure to only convert YOUR images, not the other files in the structure. I also applied the same conversion to the thumbnails to simpify things and it turned out not to bad. (Can somebody make an AppleScript maybe?)
And finally, how about iPhoto? Well, iPhoto will always export images in the color space and profile it happens to be imported with, unless you edit the image in some external editor. If you are WEB publishing "lucky", the image will come out in sRGB color space and with an sRGB color profile. And yes, I have also tried various iPhoto-WEB export plug-ins, and they also all do it wrong.
If you read all of this, you are a patient person. Thanks for the attention.

How can I check the color profile for the current document?

I'd like to create a script that checks the current document's color profile and checks it against a string, for example "sRGB IEC61966-2.1". My studio has a script that performs various functions to make sure that all the layers are visible/unlocked, checks for stray points, etc., and we'd like to add a check to the color profile because we handle a large number of files and this setting is overlooked a lot.
It's alright if this value isn't writable through script (we can just pop up an alert letting the user know that they need to change it), but I can't find where to actually read this setting! We're currently working on Macs and with JavaScript, but any nudge in the right direction would be great.
Thanks!

The Annoyance Factor. The idea was to add the color profile check once an illustrator is finished with a particular file as a kind of "clean up" before they save and move on to something else. My options as of right now are:
Create a script that saves the file in Illustrator and then closes the document, opens Photoshop if it wasn't open already (wait to load), opens the file in Photoshop (wait to load), change the color profile, and save (wait for the extra save).
Create a script that pops up an alert that says, "Check that your color profile is set to sRGB IEC61966-2.1". And the illustrator will check, save the file, and move on.
We have close to 30 people working on several files every day so wasting all that time waiting for files to load and save in a different application adds up in man-hours pretty quick. In this particular case, getting our people to do it is more efficient.

ColorChecker Passport-Color Profiles

Hi there,
I am photographing paintings with Elinchrom flashes with an even light and I use the ColorChecker Passport from X-Rite to keep a reference in order to match the colors.
Till now, I've been using the software DNG profile manager, provided with the ColorChecker Passport from X-Rite, which creates a camera profile that should be helpfull to get the right color. Once I've applied the new camera profile (after restarting lightroom), I do the white balance. It's recommended on the X-Rite tutorial to use the target number 20 called "neutral 8" to do the white balance. I've also tried the target 22 called "neutral 5", and it seems to get slightly better results.
I've noticed that even creating a color profile and doing the white balance the colors don't match. I am using a mac laptop screen that I calibrate quite often, which is not very helpful for obvious reasons, but that helps to keep track of the general look of the image, so that's why I keep the color adjustment to the RGB numbers.
I've downloaded the following PDF; here there is some information about the RGB values of various ColorChekers:
http://www.google.com/url?sa=t&source=web&cd=2&ved=0CB4QFjAB&url=http%3A%2F%2Fwww.babelcol or.com%2Fdownload%2FRGB%2520Coordinates%2520of%2520the%2520Macbeth%2520ColorChecker.pdf&rc t=j&q=ColorChecker%20rgb%20values&ei=wOCdTbG7NIyDhQelj5G8BA&usg=AFQjCNGj3wUpWC_uMxgMCeR3GI yN7kDU0A&sig2=mPf1grSAULxyMs_SanYVNw&cad=rja
Using these values and a selective color layer in photoshop I get close to the real colors, although it is not good enough.
My questions are:
1-Does anybody know the ColorChecker Passport RGB (Adobe 98) values?
2-I've tried to use the DNG profile editor because it seems a precise tool for this, but it doesn't recognise the 5D Mark II files. Is it because this application hasn't been updated? It also seems to work only with 6500K or 2850K, which is not the case of the Elincrhom 600 monoblocks I am using (which I think are around 5000K.
3-Could anybody recommend a workflow that's better to match the colors?
I have more questions, but I think these three are a good start.
Thanks!

Here are color-error analysis plots for several camera calibrations using the fine-art color-checker calibration shot uploaded, earlier.
The three profiles tested were:
1) A custom Elinchrom Flash profile I created from the color-checker using the DNG Profile Editor,
2) The Adobe Standard camera profile,
3) The custom profile provided by Gustov.
My general comment would be that the Adobe Standard profile has about the same error as the custom profile I computed using the DNG Profile Editor but the Adobe profile has a more even distribution of the color error.
The profile Gustov provided seems to be very close in the yellow area, but quite far off in the reds, blues, and violets. This can also be seen as a severe shift toward the green of the WB Tint slider value when the profile is selected for the As Shot WB as compared to the almost zero value when using the Adobe Standard profile.
These color-error plots were created using the ColorCheck module of Imatest Studio 3.7 from www.imatest.com. The program compares the measured color values from a color-checker image to the standard color numbers of the Color Checker then plots the difference on a CIE chromicity diagram, where the squares are the standard color position, the circles are the measured color position, and length of line in between is the color-error. In general, error in-and-out from the center is saturation error, while error around the center is hue error. In a 3D plot luminance error is also shown but harder to visualize without a way to rotate the plot around. Imatest provides this visualization in its Multicharts module.
I used the ProPhotoRGB colorspace when saving the TIF out of ACR because the standard ProPhotoRGB color-checker numbers in Imatest are for D50 lighting whereas the AdobeRGB standard numbers are for D65 lighting. As the image-filenames suggest, I used a linear toning curve and a black-point of 0 when saving out of ACR, but left the brightness at 50 and the contrast at 25. I tried zeroing out the brightness and contrast or using the Medium Contrast toning curve but things were way off. Using a blackpoint of 0 instead of the default of 5 also made things slightly better. There are scripts that can compute the optimal toning values for the gray patches but I was only comparing profiles, not trying to optimize them completely.

Color Profiles even when Profile set as Default keep switching - G570

I recently had to calibrate the G570 monitor. The default profile for Lenovo is too blue and for office work this may not be a problem. However, it's an issue when drawing and illustrating.
For example, the image imbedded in this thread http://www.conceptart.org/forums/showthread.php?t=232287
Shows someone having issues with color management because the Samsung profile is too yellow, and yet their display shows whites (ie in the layers palette, OS etc...)
If you look through the default Lenovo or Thinkpad calibration, your monitor is too blue to tell the difference between the hues. I calibrated mine with a Spyder Express.
Now on to the problem. Even though I have it on as default to be loaded in Color Management in Windows 7, it appears to keep flickering off and on between the default profile that comes with Lenovo laptops and the Calibrated profile with Spyder express.
Even in the Advanced settings in Color Management and setting the default as the Spyder icm profile, I still get the flickering when it comes out of sleep/monitor turned off etc.
Is there a way to keep it consistently on?
Solved!
Go to Solution.

The link I provided before is the solution.
If you have a custom color profile for color management, you need to disable igfxpers.exe from dominating it.
I disabled it in the Startup Services, and ended the process in the Task Manager. My monitor now stays at the profile I calibrated it for.
This is a problem with Intel's software and not Lenovo.

ICC Color Profile Not working bootcamp

Hi,
I have a photobooth and am trying to get my sub-dye printer up and running on windows 8 bootcamp but when i load the icc color profile for it it doesn't seem to make a difference. Just wondering if its something to do with drivers thats stopping this from working or if anyone has come across this before. I have re-added it, removed and re-added printer etc but it just doesn't make a difference.
Thanks

Ah-the driver is name is: mcpd-mac-pro9000ii-10_68_1-ea11.dmg
First thing I tried to do is delete and re-download new driver, but no luck.

Color difference once loaded in browser, color profile or something?
