ProPhoto Color Profile

If I remember correctly, I had set Aperture 2 to import my images and assign the ProPhoto RGB color profile automatically.
But for some reason, images I export from Aperture 3 all have AdobeRGB profile (which is how they come out of the camera).
I tried setting Aperture 3 preference Export, Eternal Editor Color Space to ProPhoto RGB, but I think that must only work when you order Aperture to open a photo in the assigned external editor. I just want all my images to be assigned ProPhoto from the time they're imported into Aperture.
Has something changed in Aperture 3?

Color space of images exported as JPEGs, TIFFs, etc., are determined by the Color Profile pull-down menu in the Image Export window. Go Aperture > Presets > Image Export, then change the color profile in a prerecorded preset or create a custom preset, and save the change. The selected profile will be applied to future exports that use that preset.

DNG converter converts RAW Adobe RGB color profile to ProPhoto ??

I have a Canon 5D2. there is an internal switch to shoot RAW files using the Adobe RGB profile. when I open a RAW image in CS4, there is no problem. yet when I open the DNG converted image in CS4, CS4 tells me the image has the ProPhoto color profile. I can convert back to Adobe RGB, but it adds an extra step and (I think probably) loses information. I looked for a switch in the DNG converter to speciy the color profile of the converted image, but could not find it. Any suggestions ?

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!

Photoshop RAW Processing/ Color Profile

Hello everybody,
Iam not sure how to explain my problemS that i am having.
I use Photoshop CS5
i edit my raw images on my computer
I save them to a JPEG image and i look at another computer, doens't look the same. colors are differnt
i know for RAW images i should use the ProPhoto color profile.
is there anything else i have to change ?
i hope someone could help me with this issue.
thank you very much!

Before you save the JPEG, try this: Edit - Convert to Profile - sRGB IEC61966-2.1.

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%.

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 Profiles in LR compared to PS CS2

I have my monitor calibrated with a Spyder2pro and my prints match exactly what I see on the screen in PS but nothing close to what I see in LR? I can only find three color profiles in LR (1998, Srgb, prophoto)? what's the use of editing photos in LR if I have to send them to PS to re-edit with the correct color profile? Can someone please tell me what I'm doing wrong....Your help would be much appreciated!!!
Thanks......mitch

I'm not using 'export', maybe I should give that a try but I'm guess I will have to figure out what Sams Club will want as a profile? I just save the file in photoshop as a JPG and then upload it to Sams. What would be your suggested export or saving method? Thanks for the help....mitch

Changing color profile in Lightroom 5 Soft Proofing from ProPhotoRGB to sRGB is not showing any changes, changes in Photoshop CC are dramatic

I am working with the color profile ProPhoto RGB in both Lightroom 5 and Photoshop CC. In preparing for my first Blurb book I have tried to generate pictures in sRGB in Lightroom, using the Soft Proofing feature, but there are no changes at all. Then I transfer the same pictures into Photoshop, change the color profiles and the results are dramatically different.
What can I do to achieve the same results in Lightroom

With an average monitor what you see on-screen is already soft proofed to sRGB (or something very close to it), because that's all the monitor is capable of displaying anyway. So soft proofing to sRGB won't tell you anything. You won't see any difference.
In Photoshop it sounds as if you assign profiles. That's not the way to do it. If you convert correctly you won't see any difference. Same principle as above: there may be clipping in the process, but what you see on screen is already clipped, so no visual on-screen difference.
With a wide gamut monitor soft proofing becomes slightly more useful. But still you won't see any changes occurring outside Adobe RGB. You'll get a better idea by keeping an eye on the histogram. Ideally, all three channels should taper gently off towards the endpoints. If any one or two channels are backed solidly up against the endpoint, on either side, that's gamut clipping.
If Blurb gave you a real profile, one that reflected their actual printing process, you could soft proof to that. But apparently they don't.

PS CC 2014 stopped to respect the setting to preserve embedded color profile, why?

My normal workspace is Prophoto RGB. I, however, has a large number of tiff files (dias'es scanned with a Nikon scanner) with the color space sRGB. Up till recently I had no problems - all the files kept their embedded color profile when opened in PS. I Even have the checkbox that tell PS to ask if there is a mismatch checked on. PS does not ask used to do so). This has happened after my last update of PS from PS CC to PS CC 2014. I have deinstalled Ligthroom to see if synchronization migth cause this. That did not help.
Please help.

Sorry, I do not hope that I have got something fundamentally wrong. I hope not! Otherwise please correct me!
All my own files start out as Nefs and are from Bridge brougth through ACR and on in PS as Prophoto RGB 16 bit files.
Since I also work with files that are not my own Raw files as the scanned Tiffs (scans of my 50 years old slides - scanned by somebody else on a Nikon Super Coolscan 9000 ED), Tiffs from other people or even JPEGs, I have set PS to preserve embedded color spaces and to alert me if there isn't a match between my workspace (the Prophoto RGB) and an allready embedded color space. This because I did not think it advisable to change to Prophoto RGB from Adobe RGB orsRGB as the extra colors in Prophoto RGB never were present in the Adobe RGB or sRGB files and therefore could not be "conjured" up. I, however, got the impression that 16 bit would still be an advantage when editing.
I like to start any one-layered file in ACR before entering it into PS and do not want to change that. Up till now PS nicely warned me of color space mismatches but not with these scanned files. So my present worry is if the color space of the files from the Nikon scan may be changed from a smaller to a larger space (which would not be a good idea, or?) when going into PS. I speak only of files that enter PS from ACR with ACR workflow settings of Prophoto RGB 16 bit and with the color settings of PS as described above.
As I wrote earlier today, I am beginning to think that these files do not have a color space assigned until they get into my software but I do not know enough of the Nikon Scanner to be sure. If so everything is OK and PS functions perfectly.
As written above Bridge shows the scanned Tiffs to have the Nikon sRGB 4.0.0.3001 as color profile but below in Camera Data (Exif) it says "Exif color Space: Uncalibrated".
Does anybody know if these files in realty does have an embedded color Space before entering the software outside of the scanner?
I hope my English is understandable! Please forgive the 73 year old grandmother if she has got it all wrong!

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.

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).

Lightroom 4.4 export color profile issues

Hello,
My problem is that when I export JPG's from Lightroom (100% / sRGB / sharpen for screen) the picture seems to lack contrast and the colors look less saturated (Looks like this everywhere, including Windows Preview, Firefox, Photoshop..). If I select Soft Proofing and sRGB, the colors look correct.
Also if I take a screen capture and save it as JPG, the colors look similar to my preview in Lightroom.
I have tried to export in sRGB, Adobe RGB and ProPhoto RGB color profiles but none of them looks the same as LR preview.
Thanks

This looks like Lightroom is choking on a bad monitor profile, especially if Lightroom and Photoshop are not in agreement (because they should be, always - but it can happen that they react differently to a bad profile).
Is your monitor calibrated/profiled? What calibrator? Or if not, are you using a monitor profile provided by the monitor manufacturer? (they're sometimes defective).
Export to Adobe RGB and open it in Photoshop. Put Ps and Lr side by side and make a screenshot of that. If they're different, I bet it's the monitor profile. The reason for testing this with an Adobe RGB export (and not sRGB) is to rule out any normal gamut clipping.

Color profile confusion

I'm using Windows 7 home premium, Lightroom 5.2 RC, Photoshop CS6. After working on an image in Lightroom, I went to Photoshop to do some finishing. In the process I wanted to convert the profile from prophoto to sRGB. I expected to see the choice of sRGB_IEC61966-2-1, but the selection was eSRGB, and the other one wasn't even on the list. So I did a Google search and found sRGB_IEC61966-2-1_no_black_scaling.icc but I can't figure out where to install it or even if I need to install it. I know, this isn't a Photoshop forum. But I wondered if anyone here could advise me as to what to do.
My printed images seem to match fine and so do the prints I get back from a local lab and from MyPublisher. So I'm a little confused. Any ideas?

Hi Jim I'm also using PS CS6 on Windows 7 64 bit. Color profiles are in this folder:
C:\Windows\System32\spool\drivers\color
Below is what my PS CS6 Edit> Convert To Profle> Destination Space proifle list looks like. I have an sRGB IEC61966-2-1 profile, which shows up in the Windows folder as sRGB.icc with sRGB IEC61966-2.1 'Profile Description' name using ExifTool GUI.
Here's Adobe's color profile download link, but no sRGB profile here so PS is using the Windows installed sRGB profile (sRGB.ICC in the above folder)
http://www.adobe.com/support/downloads/detail.jsp?ftpID=4075
At bottom of above of the profile list in the above page it has this link:
http://www.color.org/index.xalter
....sRGB v4, and v2 profiles with and without black scaling here:
http://www.color.org/srgbprofiles.xalter
Are you confused yet...I am!

LR 4.2 convert or embed color profiles?

Costco print services use Dry Creek Photo profiles. They ask that files be converted to color profiles in PS and say that embedded profiles will be ignored by their digital printers. I wonder if I can do this in LR4.2 without going to PS CS6.
In Lightroom 4.2, we can choose color profiles in the print module or in the export dialog. Do you know whether specifying a color profile in these will result in a converting or embedding of those files?
Thanks,
Bill Twieg
Windows 7

Thanks Andrew, that was my undertstanding as well – Also for pointing out that the Noritsu and Frontier printers have areas that are outside the sRGB gamut. For anyone interested you can create the 3D wire models here:
http://www.drycreekphoto.com/tools/printer_gamuts/gamutmodel.html
You'll need to download a VRML plugin to use it. Here's one of the Costco profiles showing the area that falls outside the sRGB gamut:
You can see an area in the Green (-a) region that falls outside the sRGB gamut, which will not render properly if you send sRGB profiled files (i.e. Export from LR's ProPhoto RGB to sRGB) to Costco.
Here's my take on Costco's Noritsu & Frontier printer workflow.
Normal processing is with Auto Correct ON, which expects sRGB profiled images with no adjustments. With Auto Correct ON the sRGB image is converted by the printer using the printer profile for the selected paper type. It apparently also applies some kind of Auto Contrast and perhaps Auto Color Correction for white balancing. This analysis is based purely on print results obtained using standard sRGB images with Auto Correct ON.
With Auto Correct OFF the printer does not apply any Contrast or Color correction and a printer profile is not applied to the image. If this is correct then it is absolutely necessary to "convert" your images to the Costco printer profile for the target paper type after making your Soft Proof adjustments. You should also preview different rendering intents in Soft Proof as outlined on the Dry Creek website. PS has more options using 'Customize Proof Condition' than available in LR.
The best analogy I can think of is Auto Correct On = "Managed By Printer" and Auto Correct OFF = "Managed By Application" (i.e. PS or LR).
I'll try to verify this with my local Costco Photo Lab manager.

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.
