Color space/profile name

I have some pictures that don't show a thumbnail in iPhoto. The info dialog for them says the Color Space is "Gray" and the Profile name is "Gr?skala - gamma 2,2". If I double-click on of these the enlarged image seems somewhat faded. The picture looks fine if I just view it directly in Preview, or ColorSync Utility. It seems most pictures have a Color Space of RGB, how to I change the Color Space of these files to RGB?

Justin:
Download the Automator application "Embed sRGB Profile" from Toad's Cellar and unzip it. Then locate the original files for those problem images and drop them on it. Next launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library and select the first three options. This should get those images compatible with iPhoto.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Question: sRGB color space profile icm

I am trying to convert a file to color space sRGB color space profile.icm. The profile is located in my library on my hard drive under recommended profiles but it does not appear in the drop down menu under edit/convert to profile. Any ideas about why? I have performed this task on my MAC at my college but can't seem to do it on my MAC in my studio...

LR converts them to the colorspace specified on the Export panel. There are several choices, including sRGB. You may need to expand various sections to see the option.

What color spaces/profiles are used?

I can’t find any information on the color
spaces/profiles/tags used for the Kuler color conversions.... can
someone please help?
Thanks

The ICC-profiles should be selectable.
They should always show up behind the RGB and CMYK entries.
Also the used CMM should be selectable and documented on
screen.
A colortransformation without knowing about these conditions
is worthlessly.
There should be a information whether the created color fits
the RGB- or CMYK-Profile-Color-space or was cropped (by the
rendering intent).
It would be nice if kuler would be allowed by the user of
that website to use the actuell CS3-Colorsetup (selected on the
users computer).
If a color theme is stored and published, all this should be
documented with that theme.
Thanks

Changing color spaces/profiles

How do I change the color profile of files that were processed using ProPhoto color space to sRGB? Thanks in advance.

Thanks Lundberg02. So if I want to change the color space of some files from ProPhoto to sRGB for web use, I should be converting and not assigning the color space, correct?

FF9 not respecting wide gamut color space profile

Let me preface this with that this all works with Safari 5.1.2 (which seems to have a memory leak, thus my reason for trying FF9 at this point). Lightroom and Safari agree. IE8, as always, is skewed to the reds in the image. FF9 is matching that behavior. I have tried going into about:config and setting color_management.enablev4 to True (didn't help). I have tried the mode to 0 and 1 (didn't help). Yes, I shut down FF between attempts.

Editing color sync profile names?

Just not sure where to post this but my main concern is with Aperture use.
My problem is that many of the icc profiles that have been added to the various support folders have nearly useless names. Also the list as it appears in "View/Proofing Profile >) is essentially not organized in any meaningful way. I'd like to be able to edit the names as they appear in the menu and organize the list (using folder if possible).
I know where the icc profiles are supposed to be located. And I know that I can use ColorSync Utility to view and edit them a bit. In fact it appears that I can change the name but when I log out/in or restart nothing happens. Also some profiles in the list are not located in any of the normal folders. I think these maybe in the printer support folders.
Any ideas? This area is a major mess. Am I missing something obvious?
Sure wish printing services would name these with some thought.

Color Space Issue with Wide-Gamut monitor

Since getting my new (and carefully calibrated) LaCie 324 monitor, I have noticed that RAW (and maybe other) images exported from Lightroom as
sRGB jpegs look washed out and slightly green when viewed outside of Lightroom (IE8, Firefox, ACDSee, windows 7 viewer). It seems not to matter whether the external application horors embedded color space profiles or not, since the unmanaged ones assume sRGB.
When I bring one of these jpegs into PhotoShop it still looks bad, and not what I see in Lightroom. However, if I Assign the Adobe RGB profile to the image, it immediately looks like the Lightroom version. And if I then Convert that image to sRGB and save it, it looks fine everywhere, even on an uncalibrated standard Dell TN LCD display.
Any ideas what I might be seeing here. A friend with the same monitor has the same problem, which is what is leading me to suspect the monitor.
The first image here is converted from Lightroom with sRGB color space. The second was first assigned the Adobe RGB color profile and then converted and saved out again as a jpeg.
Converted Only

I downloaded and ran the program. My version number appears to be 2.1 if I read the numbers right.
I am still at a loss as to why my sRGB jpegs only look right if I assign the wrong profile to them.
Here are the settings in Windows 7 for color management. The highlighted profile is the one just created for my monitor. Display 2 is my main display. Note the "viewing conditions" setting on the advanced tab. Do you think the rendering intent might be at fault here? In Lightroom, should I use Perceptual over Relative or vice versa?

Web Gallery and Color Space

Hi,
Is there any way to change the color space of the Web Galleries made by Aperture from Adobe-RGB to sRGB without exporting the photos separate first.
I'm also missing an adjustment option to set the image quality in the Web Gallery.
Regards,
JO
http://www.motivio.de

I am slightly confused by what you said...
without exporting the photos separate first.
Do you mean change to sRGB while still in Aperture? The answer would be no. The images get changed to sRGB on export. However, you do not have to export the images separately from the gallery. When you create the gallery, the images and html get created all together. So, what you do is change the export presets you are using for the web to have sRGB in the color space profile.

PS CS with color space set to Prophoto RGB - will ACR change embedded profiles?

Probably a foolish question but my problem is that I have a mixture of files:
My own files (all initially RAW (NEF) which I import into ACR as 16 bit Prophoto RGB ).
Files from family members and from slide scanning performed elsewhere - they are in 2 groups:
The first of these from elsewhere acquired files were all JPEGs that I converted to Tiffs in Bridge before setting out to edit them-- all unfortunately 8bit and sRGB.
The scanned files were scanned as tiffs but also 8bit and sRGB.
My normal procedure is that I in ACR I have set the files to 16 bit and Prophoto RGB. In PS the same but also to preserve embedded profiles. I have the impression that working with the "foreign" files in 16 bit does give me more room for editing but that I should continue with the embedded profiles.
Is there a way to ensure that the color profiles are not changed in ACR even if the line in the middle below says 16 bit Prophoto RGB (I have PS CS5). I would hate to have to change this line each time I view a file in ACR. I would hate more to loose the editing facilities in ACR as these acquired files do need som special care before they are mixed with my own in our family albums. I prefer the 16 bit Prophoto RGB option for my own files as I like to play with them - i.e. apart from including them in Photo Albums.
I do see that a logical way is to process all the acquired files before going to my own files but it is so much more practical for me to work with a mixture of the files sorted chronologically - a year or month at the time.
I would even consider getting an upgrade to CS6 if this version could help me.
Can someone enligthen me?
Thanks, Git

Hi, Tom.
The real issue here is getting accurate color. You can't get accurate color by setting your monitor profile to sRGB. sRGB is a virtual color space that doesn't describe the exact color gamut of any physical device. But, in order to display sRGB or any color space accurately, you need to get a characterization of your monitor.
Here is an AWESOME way to get access to a colorimeter: http://www.lensrentals.com/rent/pantone-huey-colorimeter Looks like for $32 you can rent this for a week. Go in on this with a friend and profile both of your monitors and hardly pay a thing. If you have a reasonably good quality LCD monitor, this custom profile you make will be fairly accurate for many months. At the very least, this is way more accurate than having no regular calibration at all.
Hope this helps!

How to find the Color Space name for a PDEElement

Hi
I am trying to find out the color space for each PDEElement in my PDF file. While doing this,
I put some debug statements ( cout stmts ) that print the color_space as integer values. I gave this list
after the code. I belive the color spaces should be something like CMYK, DeviceRGB,DeviceGray..etc.

As you may have noticed, the "numbers" you see are actually of type ASAtom -
which is a type declared in the SDK to represent reused strings. You have to
read the relevant documentation to learn how to use the SDK - there is no
way around it. The Acrobat SDK is very powerful, but also a lot more
complicated than most people expect when they start to work with it. Take
your time to learn how to use it.
In this particular case, you need to call this function to convert the

Color space and profiles clarifications

Does FCPX consider the embedded color profile of my clips ?
What is the default color space of FCPX projects ? (if any)
Can I select a specific color profile for my projects ?
My clips (according to after effect_cs6>interpret footage>color management) have this color profile embedded: HDTV (Rec. 709) Y'CbCr, but if I check out the same clip once transcoded to prores422 by FCPX there is no color profile anymore. What's goin on ?
I come from the photography world and we consider color profiles very important, what should I know about them when working with video ?
Thanks a lot

Thanks TOm, what do you mean internally ? In AE I can select a color space from a long list for my projects while FCPX discard the color profiles from the imported clips... how can it even manage them ?
Thanks

Color profile name

Please let me know on how to get the color profile used in an eps file. In Photoshop scirpting there is method colorProfileName to get the profile name.
I hope this method is not available in Illustrator scripting.

Converting RGB images (sRGB or Adobe RGB) to 709 color space.

I'm trying to determine the correct way to convert RGB images (sRGB or Adobe RGB) to 709 color space. I can't just use the "covert to profile" function to do this because it does not produce results that fall within the 16 to 235 range that 709 dictates. I've read that you can simply use the "Levels" adjustment and change the output levels to 16 to 235. While this would clearly compress the luminance to the correct range, I'm not entirely clear if the end result would be a proper conversion (i.e. if color and gamma, for example, would be technically correct.)
I noticed that converting the profile to "HDTV (Rec. 709)" does alter the image, so I'm wondering what the result would be if I did both this AND used the levels control to compress the output range to 16 to 235.
Thanks for any feedback on this.

(1)
http://en.wikipedia.org/wiki/Rec._709
(2)
http://en.wikipedia.org/wiki/Rec._601
The transfer functions for Rec.709 (1) refer to the range [0..1] or for 8 bits per pixel [0...255].
It seems that the clipping, black=16 and white=235 has to happen after the application of the
transfer function. If this should be true, then we don't have a level compression but a level
clipping at both ends, as already for Rec.601 (2), like here:
The ICC-Profile HDTV(Rec.709) in Photoshop contains the primaries and the white point
(both like that in sRGB) and the transfer functions for [0..1], coded by a LUT with high resolution,
as found by Profile Inspector. There is no clipping.
By the way, that`s the internal profile name, I don't know the file name of the profile.
Softproofing, source in sRGB, target HDTV(Rec.709), without clipping:
With numbers not preserved: no change of the appearance, as expected.
With numbers preserved: shows the effect of different effective gammas.
Your questions are very clear and I'm not sure whether my comments help. The information
in the internet is not convincing.

For P.O.D. Printing: How to Set Adobe RGB Color Space

Hello and thanks in advance,
(I'm using InDesign CS 5.5 on a Mac.)
I need to set the proper PDF export settings
For printing a book on demand, with color drawings inside on the text pages.
The onnly instructions that I have been able to find, say this:
"Submit your graphics in the Adobe RGB color space, withprofile embedded."
The Big Question: How do I do that ?
I know enough to start with
File --> Adobe PDF Presets --> Press Quality
Then I click on the "Output Menu"
and here's where I start to get lost.
for
Color Conversion ...
I think I should select "Convert to Destination"
for
Destination
I think it should be "Adobe RGB (1998)"
Now in order to embed this profile,
What should I select under:
Profile Inclusion Policy ?
And is there anything else I should be doing to get these inside color images printing nicely ?
Thanks again,
IthacaAuthor (aka ZorbaTheGeek, but the forum would not let me log in with my old screen name)

Virtually all digital printing is done via either PostScript or PDF. In the former case, the PDF is converted to PostScript viat use of Acrobat and in the latter case, the PDF is sent directly to the digital printer.
In either case, CMYK is in fact the actual destination color space. There are no real RGB printers!!! What is true is that non-PostScript / non-PDF printers (typically low end laser and inkjet printers as well as specialized inkjet and dye sublimation photo printers) do take in RGB via drivers and convert that to CMYK, but I don't believe that is what you are dealing with.
Our recommendation at Adobe for best printing results, whether for offset or digital printing, is to export PDF as PDF/X-4 with no color conversion using the default CMYK color space (SWOP CMYK) or if instructed otherwise by your print service provider, one of the other CMYK color spaces provided by Adobe or by the print service provider themselves. FWIW, most on-demand digital print devices do have settings to fully emulate SWOP CMYK printing conditions. Using PDF/X-4 in this manner allows the existing color content in your InDesign document to be properly tagged in the output PDF file and converted to CMYK at the digital printing device's RIP.
(It might also assist us if you can provide a pointer to the explicit instructions provided by your print service provider.)

New ICC v4 sRGB Color Space May Prevent Clipping Converting From ProPhoto RGB

Just discovered and tried out this new sRGB color space downloaded from this page:
http://www.color.org/srgbprofiles.xalter
Here's a cropped demo with histograms of a raw image I've been working on in ProPhotoRGB in ACR 3.7 and CS2:
http://www.flickr.com/photos/26078880@N02/2874068887/sizes/o/
Please disregard the PRMG name in the demo. I got confused as to which was which on that site and thought that this version of sRGB was a PRMG=(Perceptual Reference Medium Gamut) profile. It's called sRGB_v4_ICC_preference.icc.
Note the different color shifts using the Perceptual intent and unchecking Black Point Compensation=(BPC). Neat little features embedded in this profile, but not sure about how it renders certain colors close to clipping in the shadows. That site doesn't recommend mixed use of ICC v4 with v2 color spaces and output device profiles but I did it anyway just to see what it does.
Who knows this may be the equivalent of handing scissors to children, but I'm just one of those curious children and thought I'ld share anyway.

I'll try to respond to a few items above.
The digital values in a Pro Photo RGB file should generally be the same as for a ROMM RGB file. The exception is that all possible Pro Photo RGB values are "legal" but not all ROMM RGB values are "legal." ISO 22028-2 restricts the legal ROMM values to those with PCS LAB values between 0 and 100 L* and -128 to +128 a* and b*.
There is no enforcement if you use the illegal values in a ROMM file but as some of these values do not represent possible colors this is not advisable. I think it is good practice to try to stay mostly inside the ICC v4 PRM gamut with Pro Photo/ROMM images. You can check this using the gamut warning profile on the ICC site.
If you have a Pro Photo RGB image you should just assign the ROMM profile to it. Converting to ROMM RGB should not change anything in the ideal sense but there is the possibility to introduce rounding errors and mismatch black points.
The main difference between the Pro Photo RGB profile and the ROMM RGB profile is the former includes black scaling to zero (as is common with v2 color space and display profiles) and the latter does not (as is required with v4 profiles).
In the duck picture, the reason for the difference is the ROMM profile black is at L*=3 so this is where the lowest blacks land when converting MRC to v2 sRGB (which has the sRGB blacks scaled to L*=0). In this case leaving BPC off is analogous to turning on "Simulate Black Ink" in Photoshop Proof Setup.
All the ACR color space choices are v2 profiles with black scaling. If you want a v4 profile embedded you have to assign it (if you have a corresponding v4 profile) or convert to it.
Both the sRGB and PRM gamuts fit within the ROMM RGB legal encoding range, but if you use a v2 profile with black scaling you should always turn on BPC when combining with a v4 profile. Otherwise the v4 profile will think the v2 profile represents a device with an infinite dynamic range. When BPC is on the Color Engine scales the black point of the source profile to the black point of the destination profile.
The sRGB gamut extends outside the PRM gamut in some places, and the PRM gamut extends outside the sRGB gamut in other places. If you convert using a colorimetric intent in either direction some of the gamut will be clipped. The purpose of the sRGB v4 perceptual transforms is to minimize clipping in both directions.
I can't do this justice here but basically scene-referred images are encodings of the scene colors and output-referred images are encodings of the picture colors on some medium for which the picture colors have been optimized. You can make a scene-referred image by setting the ACR sliders (except the white balance sliders) to zero and the curves tab to linear. You make an output-referred image when you adjust the sliders to non-zero values to make a nice picture as viewed on some medium. For example you might adjust the sliders differently to get the best results printing colorimetrically on glossy photo paper vs. on plain office paper.
Often an important part of the transform to output-referred includes a midtone contrast and saturation boost. While there will likely be some highlight and may be some shadow compression, it is misleading to think of this transform only as a compression to some output medium dynamic range. In some cases the output medium dynamic range is larger than that of the scene.
Usually the transform to output-referred is more complicated than a simple gamma function.
Regardless of the image state (scene-referred or output-referred) the sRGB, Adobe RGB, or Pro Photo RGB nonlinearities will be applied to create the image data that you open into Photoshop.
We are working in the ICC to prepare more information for posting on this topic.
