AdobeRGB treated as UNKNOWN color profile

Hi all.
My digital camera jpeg image that have AdobeRGB color profile,
that appears as color shifted on monitor.
in Aperture 3.1.3 metadata tab , that treated as UNKNOWN color profile.
also in preview.app , color shift are happend.
and need manually set AdobeRGB to collect color
10.6.8 and Aperture 3.1.3 works collectful
10.7.0 and Aperture 3.1.3 unknown color profile.
is this bug?
is there any person like this?

Bridge doesn't recognize color profiles

Dear Adobe community,
I'm using Adobe Bridge CS5.1 (4.1.0.54) and Illustrator CS5.1 (15.1.0), and I'm experiencing a very confusing and disturbing color management problem between these two applications. In short, for some unknown reason Bridge doesn't seem to respect or simply cannot read CMYK color profiles that I've applied to an artwork within Illustrator, but rather labels the file as "Untagged" and displays it with clearly desaturated colors. To illustrate the problem I've created some screenshots having Bridge on the left hand side and Illustrator on the right displaying the same illustration with various color profiles applied. That is, in each case I assigned different color profile to the image in Illustrator, saved the file and took the screenshot of Bridge and Illustrator both displaying the image. Now if you look closely then perhaps you notice that the only time I got a visual match between these applications was when I switched the file to a RGB mode within Illustrator. But even then Bridge did not recognized the correct color profile but interpreted it as "Untagged". Here are the screens:
Bridge "Untagged" vs. Illustrator "U.S. Web Coated":
Bridge "Untagged" vs. Illustrator "Coated FOGRA39":
Bridge "Untagged" vs. Illustrator "Don't Color Manage This Document":
Bridge "Untagged" vs. Illustrator "Adobe RGB":
Hope you could see the difference from these tiny images. Looking from my monitor, I can tell you for sure that they are definitely off, except the RGB versions of the illustration. This made me surmise that perhaps Bridge can only display Working RGB profiles correctly and not anything else.
Here's also my color settings, just in case…
So... Why is that??? Why are these applications showing me different results while my color settings are supposed to be "Synchronized"? Is there a way to fix this? I have tried to play around with the settings and looked for a solution in the web but to no avail. Could you please help me to find a soulution to this disturbing problem?
All the best,
Juhani

You may have used the broken global Purge Cache command in Bridge Preferences, or the cache is otherwise corrupted. Try Purging the Cache through the Tools menu in Bridge for each folder. Tools > Cache > Purge cache for 'foldername'.

Color profiles for I photo books

Is there a desired color profile to use for printing books with i photo
My images are currently adobe-rgb. jpegs brought in from CS
When I print the images thru CS they look great.
When i print them thru I photo book or the PDF they look very dark and muddy...and would assume the same of the book printing online.
any ideas on how to get the best print.
Is there a color profile availabe from the online book printers or are we just winging it
Also tried converting one page to S-RGB Still Muddy / dark thru i photo book
and PDF Print. And just fine thru CS
Any Ideas??
Thank you

I guess I am going to throw caution to the wind and see what happens.
Only one way to find out, Right
Though I did go back and lighten my images. Also
Ran color synch utility, which fixed 11 corrupt color profiles.(none of the 11 profiles pertained to i photo)
I guess I am afraid to use pref setter,, to set the key embed color profile.
Confused as to what that means??? Does that mean that all my CS Adobe-RGB jpegs will keep their color profile???
Also implanted one image as an SRGB vs the rest which will all be AdobeRGB
Oddly my color management in CS is almost Flawless. Yet, get me out of CS and I am completely lost!!!! Complicated stuff
Toad, I did want to pass on that AdobeRGB 1998 is a much more robust color profile then SRGB especially when it come to printing on Epson. It might be worth experimenting with and if you really want to get into it there is also
Pro photo RGB which is Huge color space, but a beast to work with

Choosing Color Profiles for Images Created on Film

I just finished sending feedback to Adobe on one of its tutorials. The following is a copy of my message explaining my present predicament.
<< I have scanned film negatives and positive film transparencies dating back to the 1950's .I was the creator of most of these images but I do not remember the make or model of the cameras I was using at any point in time prior to 1974 and they all lack metadata. Prior to 2000 I used iPhoto and PS Elements for scanning, toning and development. Thus I can only guess what color profile I should use. I want to create TIFFS that will serve a dual purpose: exporting two formats, one for electronic sharing and the other for printing. On the Adobe CC, if I guess wrong, LR 5.6 64bit crashes immediately. Prior stand alone versions of LR and CS6 let you know that you had a color inconsistency, but they did not crash when you had made a wrong choice between srgb and ProPhoto. ACC gives me more options, but no warnings unless I am missing something your Help Files should contain.>>

Color Profile Question

I recently purchased a new PC and have been working from it for about a month or so without any issues. My client sent me an email saying that her images were appearing muted on her computer screen prior to printing them off of a few common photo labs. I looked into it and tried it myself and it was indeed correct. All of the images edited on my new PC were muted...my first instinct was that it was the color profile. I converted the image to sRGB and it fixed the problem. Now comes the problem....my photos are saving under the wrong color profile. How do I prevent this from happening so that all my images are automatically saved the my preference of color profile. I hope this makes sense because my mind is spinning from trying to figure this out! Thanks in advance!

3. My client has a print release, I use WHCC to print my pictures and I believe they require sRGB as well.
4. Yes I always shoot in RAW.
Thanks for taking the time to help, I looked at my Lightroom color settings since that's how I import my pics and it was set on Adobe Pro I believe... I changed it to sRGB.

Thanks for the info : I'll start with the 4th question because it's the less known factor with Elements
If you shoot raw, the settings of your camera (Adobe RGB) will be ignored. This setting works only with the out of camera jpegs. A 'raw' file has no color profile, so PSE needs to know which profile you want for the conversion. You won't find any menu or dialog entries in ACR for that purpose. So, to convert the file when you 'Open' in the editor, PSE looks at the settings in your editor (my question #2, Menu Edit/Color settings...
If you have chosen option 1, 'Always optimize for computer screens', PSE will convert the raw file to sRGB profile.
If you have chosen 'Always optimize for printing', PSE will convert to aRGB...
If you want to take advantage of the slightly wider color space of Adobe RGB because your home printer can use it, select the second option, but if you have to send the picture in sRGB, do not forget to convert before sending. Menu /image/convert color profile.
If you don't want to bother, use sRGB with the option 1. You won't risk forgetting to convert the client version.
Never use 'No color management' in the menu /edit/color settings
If you first convert to sRGB with option 1, you won't get any advantage to convert to aRGB afterwards

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.

Total ink weight for fabrics or suggested color profile.

My client's approved their project and I now have some tradeshow pop-up panels to "convert to CMYK" that will be printed on [some stretchy unknown] fabric. I was wondering if anyone knows the total ink weight for the [stretchy] textiles used for tradeshows or if there is a suggested color profile to use during conversion (or if the real printers actually want this... I had seen that some textile printers actually prefer LAB). In the past I took a guess and used Web Offset Coated and it came out "okay" on Tyvek where something was printed locally, but these are a "stretchy fabric," so I'm guessing something like Web Offset Uncoated? I know the inkjet printers are capable of outputting a lot of ink and do not want the fabric to run or visually bleed though, also I wasn't sure if the tradeshow fabrics are printed with the typical oversized inkjet printers at all.
The "print vendor" (middleman) told me emphatically CMYK conversion was a must, but seemed confused by the question of suggested color profile for converting and could not provide an answer. Unfortunately they're in a deal with my client and the producer of the booth so I'm stuck with them. Also they have not provide the contact info for the producer of the booth. I'd rather not use uncoated because I know there will be a significant loss of vibrance in the printing. So I come to the plethora of knowledge here at Adobe.

Okay so I received more feedback from my client. When they were pitched it sounds like the vendor is going to print with Dye Sub. I'm thinking the middleman might not know what he's talking about (since they couldn't tell me which CMYK) so to be safe I'm going to provide the files in RGB (Adobe 1998) AND CMYK (U.S. Web Offset Coated SWOP). That way they can pick and choose. I got U.S. Web Offset Coated as a suggestion off a search for CMYK conversion and Dye Sub on large format printers. Hope this helps someone.

Reduce bit depth or convert color profile first? (best practices question)

For making final deliverable files from working files, is it best to convert to a new color profile before reducing bit depth? Or vise versa?
Our working files are 16 bit with the ProPhoto color space. Our deliverable files are 8 bit AdobeRGB tiffs and sRGB jpegs. We convert using relative colorimetric with black point compensation. Does it make a difference which order these changes are made in?
Thanks in advance for your help!

A profile conversion recalculates RGB values, so yes, it should be done in 16 bit depth.

How do I embed a color profile in an untagged picture that is displayed incorrectly as sRGB?

I have a set of JPEGs that have been stripped of their color profiles (AdobeRGB). Lightroom assumes that they are sRGB images and displays them incorrectly. Is there any function in the program that will let me embed the correct (AdobeRGB) profile to the photos, preferably without re-compressing them?

It looks like the developer of ExifTools GUI is no longer supporting it:
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=5370.0
I tried using an older ExifTools Gui v3.38 with the latest ExifTools v9.47 windows installer download and it works fine. It also does NOT recompress the image data when using the 'Import ICC/ICM Profile' tools. So there's no need to create TIFFs to change the profile on your JPEGs without altering the image data. Try it!
I've uploaded a ZIP file, which contains a folder with everything you need. Download, unzip, and place the folder anywhere on your HDD. Copy and paste the shortcut 'ExifToolGUI 3.38 (ExifTools 9.47)' that's in the folder to your desktop. Nothing is installed – Exif GUI is a standalone app. If it doesn't open you may need to right-click on the shortcut and selct 'Run As Administrator.'

Web Colors: Washed out. Color Profile?

When using lightroom, I find that photos that are exported as Web images appear washed out and lighter than when I'm in the "Library" section. I find myself compensating by darkening the images in the Library to get the just right in "Web".
I guess I attribute that to a mismatched color profile. But I can't find any settings saying "the Library color profile is AdobeRGB and the Web profile is sRGB" or something like that.
Where is that setting? Am I crazy? Again? :-)

After so many people here and in every other photography forum asking why their images look 'wrong' in a browser, and the answer being, over and over, that they are using the wrong color space for output, it should be obvious that the reason that they notice and catch the problem is because they are using a non-managed browser. The ONLY reason they caught the problem is because they are using a non-managed browser. If they are using a managed browser, they won't catch the problem.
I would much rather use a browser that represents an average view and have confidence that people are seeing something reasonable, than assume that everything went right and post stuff indiscriminately and in a sense blindly. After all, if there is going to be so much variation between monitors, why stress out with color management in the first place. Just calibrate your monitor so you have a decent baseline and move on. But have SOME way to know that the workflow went as expected... use a managed browser and that final check is inexistent.
Suppose you print at a place like Lulu.com. Would you upload and order
50 copies of a book before you buy one copy of a book and make sure that everything is correct? That would be just plain stupid. Well, putting up a website without checking it on a non-color managed browser is just about as silly.
To each his own... some advice is practical, some is theoretical... understand the theory, but live in a practical world. And take simple steps to catch stupid mistakes, like making sure that you use a non-managed browser to make sure that you output the right colors.

Sigma DP2 - no dng color profiles available, only embedded

Converting X3F raw files from the Sigma DP2 a color profile created with the X-Rite Colorchecker Passport doesn't show up in the panel Camera Calibration. Instead custom profiles created for Canon cr2 raw files from a Canon 5D are showing up when working with Canon raw files.
Is this a bug of Lightroom?

Wow, I'm so glad Eric Chan is in this problem... unfortunately it's not the only one :
There is the fact that processing is locked to black and white when the white balance was set to black and white in Sigma Photo Pro (even if the color data is still there).
I know SPP writes in the files, it's bad, but Nikon's Capture NX does it and it doesn't change the way NEFs are treated in lightroom (or at least not to such extent).
Better default profiles for the sigma cameras would be a major plus too.

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.

Problem in Finding Color Profile of an image?

Hi All,
I am working on applet to read, resize and upload images. i am able to do all this using JAI but there is one more condition that needs to be full filled by my program i.e. to check the color profile of image before uploading (such as sRGB, Adobe RGB 1998).
I tried getType it give me the int number for diffrent color profile but it is not able to differentiate between sRGB and adobe RGB 1998 colour profile. How to get the colour profile embeded in the image.
Thanks
Rohit.

Yes, but its a profile (rendering and editing data calibration) for imaging not any particular java image(in crude terms at this point) [http://www.adobe.com/digitalimag/adobergb.html|http://www.adobe.com/digitalimag/adobergb.html]
If you want the maths for the image data profile [http://www.adobe.com/digitalimag/pdfs/AdobeRGB1998.pdf|http://www.adobe.com/digitalimag/pdfs/AdobeRGB1998.pdf]
presumably you were returning int getType() from a BufferedImage , the adobe profile image data is 24 bit true colour and heavily implied to be related to imaging data from "capture devices" which then implies from no mention in their documentation of "alpha component" , so in java any 24 bit non-indexed colour model RGB alike the windows bit map as the getType() "constant field value" int would be acceptable pending and other colour model excluded for render purpose of true colour(read BufferedImage API pages' "constant field values" for image type).

Smart collection has "source color profile" as filter option, does not work on camera profiles

In Lightroom 5 i tried to use the "source color profile" filter option in smart collection, however it only seems to work on rgb files (jpg, tiff) that have a profile embedded. It does not work on values like "Adobe Standard" which is a "source" profile of a RAW file, or any of the camera profiles i can choose fo given Raw file. What am i doing wrong?
The Help does not give any clue on this, nor does the coverage by any of the Lightroom guru's like Juleanne Kost.

In my opinion the filter is acting correctly.
The Adobe Standard profile is not a profile defined in the source file, it is a profile assigned to the file in the raw converter and used with raw files that do not have a source color profile, already, so to me the filter is acting correctly because “source” means where the profile comes from, rather than what profile a master photo has had assigned to it.
The source-color-profile option is useful to determine the size of the color gamut in a file’s color numbers which indicates its suitability for various purposes: An sRGB file can be safely uploaded to the web, an AdobeRGB file is going to look right on a wide-gamut monitor and printablebut shouldn’t be uploaded to the web, while a ProPhotoRGB file has a large color space and can be safely edited in a way that adjusts the colors significantly, especially if it is 16-bit, without color-banding or posterization, but a ProPhotoRGB file will probably not look good if directly uploaded to the web or sent to a print-shop that doesn’t do their own color profile conversions.
I would agree that being able to filter raw files based on the assigned color profile would also be useful, but this is a different thing, to me at least, than filtering by the source-color-profile.

What is Acrobat's Default Color Profile?

Hello,
We have a client's client who used a novice graphic designer who didn't color manage, and created a PDF containing colors that the client is pleased with. Trouble is, we have no idea what the desiner assumed as the color profile and the color profile that the client's Acrobat defaults to when displaying the PDF. And now we're having trouble recreating a PDF that the client deems matching. Our office has long since switched to ProPhoto RGB as our default RGB color profile, so we don't know what Adobe Acrobat ships with as its default (assumed) color profile when there are none embedded/assigned in the PDF (ours is now ProPhoto RGB).
1. Can someone who's not monkeyed with their color settings open up their Acrobat and look under the Preferences (ctrl-k), and "color management" and let me know what the working spaces read?
Also,
2. Is there a way to know what (if any) color profile a PDF has embedded in it? I cannot seem to find it in the PDF's metadata, and typically play with the "output preview" settings until I find one that doesn't alter the appearance (not the most efficient).
Thanks!

DeviceRGB is the default condition for many PDF creation workflows as it was the very first one supported in PDF version 1.0. - because PostScript 1.0 initially supported DeviceRGB and DeviceGray, with DeviceCMYK arriving later. ICC-based spaces came in PostScript 2 (PDF 1.3).
"Device..." spaces simply mean that the color data is preserved as-supplied from the original material - for example a scanner will see a particular red ink on the paper and record it with a certain RGB value. Unless that scan is subsequently assigned a calibration profile, the bitmap image may not look identical when re-printed but it is "accurate" in terms of what the scanner wrote to file. You can think of "Device..." spaces as being "raw data", so if you have two photographs on a PDF page, both from different sources but with DeviceRGB space, then pixels of (123,0,0) in each image will be an identical color on one particular user's monitor and printer. That color will only match the actuality of what was photographed (and what other users are seeing) if the user's display hardware is calibrated, but that's a different question entirely. Acrobat cannot correct for an uncalibrated monitor.
In the very early says of PDF and PostScript it was adopted as a print/prepress format, so color accuracy was important and features such as Output Intents and PDF/X were rapidly developed. Now, the majority of PDF files are never printed and many are designed with on-screen display as the only planned use - where RGB and unmanaged colors are perfectly acceptable. Nobody will ever notice the difference between AdobeRGB and sRGB when peering at a PDF file on a cellphone, but embedding the profiles will dramatically increase the filesize.
