Convert to Profile colour shift

Can anyone help me deal with a problem that affects some AdobeRGB files when I convert them to SRGB? In a very small number of cases when I convert to profile (srgb IEC61966-2.1) there's a noticeable shift in certain vivid reds and greens; they become much duller and in some cases the colour actually changes. When this occurs it's usually apparent in colourful clothes such as Indian saris. I'm not referring to limitations in the srgb colour space. After I've worked on the Adobe files in Photoshop (CS6) in a wide gamut environment I view them with my monitor (Dell U2713H) set to emulate the srgb colour space, then make any Hue/Saturation adjustment before converting to profile and saving as JPG files with embedded profiles for uploading to the web. In most cases the converted file looks the same as the pre-converted file, but sometimes there's this marked colour change somewhere in the picture. For example, in one case a turquoise shawl became a dull blue; in another, a vivid green stripe on a dress became a pale greenish-yellow. In the former case when I checked the colour data I found that all red had been stripped from the shawl, making it impossible to do any further tweaking with channel mixer or colour balance tools to get the original colour back. The change is visible in Photoshop, so it's got nothing to do with my image viewer. As soon as I click on 'convert to profile' the colour goes.
Is there any way of dealing with this problem?

I agree with your comments about saturation and B/W. When I think of great photos by acknowledged master I tend to think of B/W photos. In a photography book I have the best photos are either B/W or colour photos where the colours are very muted with subtle gradations. I am constantly having to resist a tendency to overdo saturation layers in PS. Thanks very much for taking the trouble to put together those gamut graphs. Much appreciated.
D Fosse, I like your picture very much. The green looks just right. Out of interest I opened it in Photoshop in 3 different versions, firstly as it is, secondly converted to AdobeRGB and thirdly with the embedded profile discarded. In the last case the green appeared over-saturated and unrealistic.
I've attached the image I referred to earlier with the green-striped dress, again with an Adobe embedded profile and with an srgb profile. Neither has had any colour enhancement in PS, though I bumped up vibrance slightly in the RAW processing.. Viewed in an srgb environment the green is the only colour that shows a change; any change in the magenta is imperceptible.
There are still aspects of colour management and gamut that I haven't quite got my head around but I'm on a learning curve, and you've all been exceptionally helpful.

Colour shift when using 4.2 Edit In to adjust a NEF file in CS6

If I choose Edit In and CS6 the resulting image in CS6 shows a marked colour green/yellow colour shift.
The LR4 external editor is configured to edit using ProPhoto RGB with 16 bit TIFF.
However, if I use the Export option with the same settings and then open the image in Photoshop it is fine.
Equally, if I first convert the NEF image to a DNG and then use Edit In with the same settings it also appears fine in Photoshop. This would appear to rule out any issues with monitor profiles (monitor profiled with i1).
Therefore this appears to be an issue with NEF files (Nikon D3) using the Edit In facility.
Also for some obscure reason it also does not always give the option to Edit a Copy with Lightroom Adjustments and just goes straight to Photoshop (even though it has been adjusted in Lightroom!).

manicfoto wrote:
Richard, perhaps I have not made the issue clear. If I import an image into Lightroom and choose Edit In Photoshop it should go straight to Photoshop as no changes have been made in Lightroom. However, if I make any adjustments in the Develop module and choose to make further changes in Photoshop I should have the option to Edit a Copy with Lightroom Adjustments etc. This dialog is not offered consistently.
If I make a change in Photoshop it should (and does) correctly save it as a new TIFF file. Again if I make any adjustments in Develop module and then choose to make further changes in Photoshop to the TIFF file it should still offer the dialog box with the copy options. Again this is not happening consistently.
Richard correctly explained how 'Edit In' works with raw files, at least that's the way it does on my Windows 7 64 bit system.
When selecting 'Edit in' with a raw file the 'What to Edit' popup with options for 'Edit a Copy with LR adjustments,' 'Edit a Copy,' and 'Edit Original' will not appear. Instead a TIFF file is created in system memory with LR adustments applied, which then opens in PS. Until you hit 'Save' in PS the TIFF file resides only in system memory. Once you hit 'Save' or Save As' (with the same folder location) the TIFF file will appear inside LR with both the LR and PS adjustments applied.

trshaner, I have done some further testing of the DNG files, and they do, in fact, also exhibit the same colour shift behaviour, although the amount of the shift seems to depend on the original image - some images show a more marked shift than others which was not obvious to me at first.
This is consistent with LR output rendering engine problem if both the NEF and DNG copy for a specific image take on the same color shift. Since the effect is very subtle on a single conversion I can see where you might have confused the DNG as looking OK.
manicfoto wrote:
I then performed another test with a TIFF file and although the change was smaller the colour definitely shifts, with the amount of shift being determined by the contents of the original image, so I have to conclude that I have the output rendering issue mentioned earlier in the thread.
Incidentally, the colour shift issue is also found if I use the option to Open as a Smart Object in Photoshop.
I have re-installed Lightroom 4.2 but the problem is still the same.
To really confirm that this is being caused by the LR output rendering engine you will need do an additional 'Edit a Copy with LR Adjustments' to the TIFF file. This will create a 2nd TIFF file, which you can then select and then 'Edit a Copy with LR Adjustments.' I would do this at least three times to insure you can see the "cumulative' effect from the LR output rendering engine conversion. You will want to compare the last TIFF file (4th) with the original (1st) TIFF file.
Please try this and post the histograms for the original TIFF and last Tiff with three cumulative 'Edit a Copy with LR Adjustments,' or confirm that's what you have already done in the above posted histograms.

Illustrator 10, Convert to Profile: mental block or sudden blindness?

I've either hit a mental block or have become temporarily blind, but I cannot find "Convert to Profile" in Illustrator 10.0.3 Mac, running Tiger 10.4.11.
Any hint or slap on the head that might jog my memory will be appreciated. The Help files have not been helpful yet. As the fortune cookie said, old age always comes at a most inopportune time.
Thanks in advance.

Or do you mean Assign Current Working Space (colour profile) when opening a file?
No! When you Assign a profile, you preserve the numbers but you change (wreck the hell out of) the colors. When you Convert to a Profile, you change the numbers but you preserve the colors.
It seems that old AI 10 did not have such a menu Command in the Edit menu, as Photoshop has, so the workaround would be to close the file and pen it again, at which time you do get presented with the choice of CONVERTING to a profile.

No, Changing your Color settings is a global dialog box that affects your working space, not your open document.
Thank you for your time anyway.

Colour shift in save for web when saving on PC and then viewing on Mac

Hey peeps, I am aware of this colour shift when saving images for web. I have a designer resizing, cropping photos, and then saving on PC. He uses PC and when he sends the photos over to me on my Mac there is a big colour shift (photos are much lighte
Could anyone please explain exactly what he needs to do in order for these photos to look the same as the originals on my computer, basically no lightness shift? Any help would be much appreciated.
Thanks
Adam

Because the WWW is based on untagged (2.2 gamma) sRGB - your genius is probably sending you untagged sRGB if they were Saved for the Web (that's how I prepare my Web color).
Your Mac display should be profiled to 2.2 gamma (you are likely at the old default 1.8 gamma now if you're seeing a lightness shift on untagged sRGB)...if you want "your color" back in Photoshop, you will need to (re)Assign the sRGB profile...

How do I get my .csf file setting to show up in the Convert to Profile or Proof as menu choices?

I received specific menu choices for Color Settings from a commercial printer I use. I went to Edit<Color Settings and saved them as a .csf file in User/Library/Applications Support/Adobe/Color/Settings. I named the .csf file after the printer. When I go back into Edit<Color Settings and open the Settings menu I am able to choose the settings I saved from the list of settings. Now I open an image in PhotoShop and go to Edit<Convert to Profile. In the dialog box I open the Profile menu, but the settings I saved in Edit<Color Setting are not one of the Profile choices. Am I confusing Setting and Profiles? How do I Convert an image file to the setting given me by the printer? I also wanted to proof as per the printer's settings. When I go to View<Proof setup<Custom I can choose Working CMYK Web Coated SWOP 2006 Grade 3 Paper, which is generally the profile this printer is using. But I can't choice my specific color settings saved under the printer's that I previously saved in Edit<Color Settings. In the Proof Setup dialog box when I press the load button I can navigate to the Settings folder where my .csf file is saved, but it is greyed-out so I can't choose it. Anyone know what I'm doing wrong? Please advise/help. Thank you.

"Am I confusing Setting and Profiles?"
Yes. A Color Settings File (CSF) will contain values for all the controls in the Color Settings dialog. One of these controls specifies the profile to be used for the CMYK Working Space. That profile will be used by default when you create a new CMYK document or convert an RGB (or some other colour space) document to CMYK.
The profile, not the CSF, will be at the top of the list of CMYK options in the Convert to Profile dialog, as "Working CMYK - <name of your CMYK profile>". However, you may want to skip that dialog and instead do Image > Mode > CMYK, which will simply raise a prompt asking you whether to proceed with the conversion to your CMYK Working Space profile.
In View > Proof Setup menu, item "Working CMYK" also will use the profile that's specified in Color Settings, then "Custom..." in the same menu will give access to options to simulate paper and black ink.

Colour shift problem in CS5 not in Lightroom

All good so far. Colours on my profiled monitor are good. If I then print this file through Q image all is good (and this is most of my files!) . Happy days! However if I open in CS5 (Colour settings below-which have not changed for 10 years!) the colour changes. I am getting no profile mismatch warning (I shouldn’t – file is adobe rgb which is my working space). But there is a noticeable colour shift. If I do nothing to the file and resave the colour has shifted. I have tried opening a file/ saving with a different file name and printing the two on the same sheet of paper to eliminate printer issues – the shift that I see on my monitor is there. Why would opening an Adobe RGB jpeg in CS5 change its colour? It certainly never happened before. Also if within Lightroom I click “edit in PS”, open the file and resave the colour has shifted..
((I have also tried preserve embedded profile but this doesn’t solve the issue!)
My workaround is to do lightroom conversion, (colour correct!), Open and edit in CS5 (colour shift) save as different file name, Import into Lightroom (Now says embedded profile (This is correct I think) Do nothing in terms of colour (which now looks correct again!) and export (Wow Correct colour Again!!)
Does anybody know what is going on??
I have used half a roll of paper doing test prints and have established the following:
My monitor profile is correct, (What I see is what I get!)
QImage setting & My printer profile is correct ( What I see is what I get! By printing the two files on the same sheet (this will eliminate printer issues) I can see the CS5 file is very different - as on the monitor)
All lightroom exports are correct (what I see is what I get!)
I also opened a file on CS3 (across a network to a non colour managed machine but with adobe rgb work space, did nothing with the file but resave and the colours shift again!
I attach samples below: The difference reminds me of what an Adobe RGB file looks like on a non colour managed monitor – Flatter (no punch) but also a slightly green
Any Help would be much appreciated!

NB Also set to do nothing after export!

Very generally, they both describe profiles. ICC is the standard International Color Consortium format for profiles and ICM is Microsoft's flavor (standing for Integrated Color Management, I believe).
Photoshop et. al. are able to use both, but even a name match wouldn't mean the contents are identical. There is some possibility that they actually are equivalent under the covers in this case, and that my spotting the slight difference in names isn't the source of the visible color differences. It is almost certainly why the warning message is being emitted, though.
These may help further with definitions, but are not light reading by any means:

Photoshop to Lightroom Colour Shift

Hi all,
I've recently upgraded from CS5 to CC after purchasing a Nikon D7100 over christmas and thus needing the latest versions fro RAW support (Nikon NEF).
My problem is I am experiencing colour shift between Photoshop and Lightroom after upgrading. I have set Lightroom to use 16-bit ProPhoto RGB images when editing in Photoshop. My computer is a Late 2012 MacMini with an Apple Thunderbolt Display.
I originally posted this in the Photoshop forum and have moved it over here after being recommended to do so.
The image below shows the problem, where the colour is correct in Photoshop, but not in Lightroom.
In the other thread we went through the motions and eliminated:
D7100 Camera Raw Profile
Lens profile
Screen calibration and profile
It seems most likely at this point that Lightroom is applying some kind of alterations to the image settings. If I Right Click a problem image in lightroom and say "edit in photoshop with lightroom adjustments" that colours appear incorrect in photoshop, too.
Can anyone make any suggestions here? I can't seem to get anything I shot last weekend out of lightroom with the correct colours!
Thanks,
Dan.

A “raw” HDR image has darks that are too dark to see detail in and lights that are too bright to see any detail in. The process of “tone mapping” is what scrunches all the floating point values into the normal range of black to white. Once an image is tone mapped its pixel values all fall into the range of zero to whatever the maximum value is for white in a 16-bit or 8-bit format and it can be saved as such. The 32-bit floating point image is supposed to be temporary on the way to an 8- or 16-bit image. Personally I save the original 32-bit image in a separate file from the tone-mapped 16- or 8-bit image so I can always go back and revisit the tone mapping operation.
LR supports 32-bit images otherwise you would see nothing. Here is a discussion about why things look different that includes Eric Chan, an Adobe Raw Engineer, to someone bringing up a similar concern a little over a year ago:
ttp://feedback.photoshop.com/photoshop_family/topics/lightroom_preview_of_hdr_tonemapped_i mage_doesnt_match_what_is_shown_in_photoshop_acr
It used to be that Photoshop was the only Adobe product that could open 32-bit files and tone-map them to 16- or 8-bits and I would argue that it did an unsatisfying job. Eventually this capability was added to LR and the ACR plug-in for Photoshop which does a better job, but being raw converters, the starting point looks brighter on screen.
Photomatix is a payfor product that also does a good job with both merging and tone-mapping to 16- or 8-bits. It comes with both a standalone and a plug-in interface. There are others, but Photomatix is the one I’ve tried in the past.

Hex colour shift from Indd to PH, both assigned sRGB

Hi everyone. I am doing some wire framing in indesign with buttons and other colours. I would like to keep everything pretty tight so when I use anything graphics from indesign and place them in photoshop I want the hex values to match. I have assigned both programs with sRGB IEC61966-2.1. But when I copy and paste into Photoshop the value changes slightly.
I have 2 colour with Hex values of:
#59B124 - Green 89/177/36
#FFD911 - Red 255/217/17
Made using the great script by in-tools. But when placed in ph the colour shift ever so slightly. Green becomes #58b023 and the Red becomes #fc1713. Is there any way to make sure when these copy over the colours match.
Thanks
lister

by not including a profile and not colour managing either apps
Not including a profile doesn't mean there's no CM. If there's no document profile assignment, the Color Settings' Working Space is used instead. So without document profiles, and an RGB Working space of sRGB in both programs, the preview of 89/177/36 would be the same. It looks like when document profiles are used there's some kind of conversion when you cut and paste, which shouldn't happen.
You could leave your docs with no profile assigned and then when you save for web include the working sRGB profile

CS5 Save as Jpeg gives colour shift - OK as PSD/Tiff

Hi Guys,
This is a follow on from the "lightroom /CS5 colour shift post" which I have now narrowed down to the following:
I use Win XP pro sp3 fully updated, Dell PC 4GB Ram, LR and CS5 both latest versions. Print through Qimage to epson 7880 - Workflow/ monitor all fully colour profiled. Workspace adobe 1998
Colour setting:
These settings have not changed in years.
My issue is that if I open a jpeg image in CS5 (colour is correct), save as psd or tiff (the colour is correct)
BUT if I save as jpeg (having done nothing to the file!) the colour on the saved file has shifted
I am not getting any profile mismatch warnings - this problem has only surfaced in the last few weeks.
Any ideas would be much appreciated
Thanks, Nigel

Hi again, Sorry had a busy weekend so I had
to disappear! Ok Firstly I cannot understand why a monitor profile could
be the culprit (just to rehash I develop a jpe
g in LR (colour is good, Print is good) Op
en in Cs5 colour looks same. If I save as PSD or Tiff Colour stays the same and prints same - Happy days!
But If I save as a jpeg (with or without a file number change the colour looks ok in CS. BUT when I close it & open it again in CS the colour has shifted. Also this shift is clearly visible in LR and QImage and in the print! It seems to me that the save as jpeg is the problem.
But just in case I reprofiled the monitor this morning (Eye1 display2) but problem is the same.
It has been suggested to me that the best thing to do is to reload CS5 might cure this. Any thoughts?
Also if i do that (I am on upgrades since v5 missing only CS4) Is there a way to skip loading all the versions?
Thanks Nigel

PS CS6 - Convert to profile - wrong color preview with AdobeRGB - AdobeRGB conversion.

Hello,
I've discovered what looks as a little bug to me in CS6 (as compared to PS CS3 and CS4).
I would be inteterested if others could confirm it (or explain it to me)
When using Convert to profile, AdobeRGB->AdobeRGB "conversion" bugs in the preview. Since there's no actual conversion, the preview should remain the same but instead shows a strong contrast shift.
Here's my workflow:
- Working color space : sRGB (I use Europe General Purpose 3 preset)
- Open a document in AdobeRGB (original profile preserved, no prior conversion to sRGB), no soft-proofing activated
- I run "Convert to profile", Source profile is Adobe RGB. Now if I go for Destination profile: AdobeRGB (which is of course "pointless"), I see a color shift in the image preview. If I run the conversion, the image reverts to normal, hence this just affects the preview. Note that converting to other profiles like sRGB doesn't give a wrong preview.
"Convert to profile" settings are Engine: Adobe (ACE), Intent: Relative Colorimetric, Use black point compensation and Dither. Altering these settings doesn't correct the bug I'm mentionning.
This visual preview bug only affects AdobeRGB -> AdobeRGB conversion (again, yes, I know, it's pointless)
I've tested the issue on two separated machines (Windows 7, PS CS6 x64)
Do you experience the same issues?
Thank you!
JS

This has been reported before and can be easily reproduced. I've never heard that it's any kind of special feature - I'm with you: Bug.
I suspect because it's a preview-only problem and doesn't affect the image quality, and it's kind of nonsensical operation anyway, Adobe has assigned it a priority level below that of pretty much everything else.
But if it were my software I'd certainly be embarrassed that it does that.

Dng colour shift from bridge to jpg's....cs2

Hello everyone. I am very new at this so I really hope that someone can help me.
I have a new eos 5 mark 11.
I use cs2 which doesn't recognise the RAW images. I have downloaded dng and started colour correction in bridge.
I have saved the files as jpg's but........ there is a huge colour shift. They look terrible.
What am I doing wrong?? please help.

I'm trying to figure out the same thing. As far i discovered that Photoshop as default display images without any proofing. Fax viewer in windows is color managed (at least in theory). That's why adobe created sRGB (for viewing on screen).
Try to turn on proof colors (ctrl + y) and set it to monitor RGB. This will show you your terrible jpg's in PS.
Saved jpg's in PS looks brighter, but less vivid.
RAW (converted or not) files saved as jpg's look far worse (terrible, as you said) in windows fax viewer, but I don't know why. Try to compare it, shooting RAW + jpg. Jpg's looks ok (better in bridge), RAWs looks ok in PS, but after saveing them as jpgs... (without proofing) they are so bad! RAW are great, but sometimes it's pointless to shoot in RAWs, becaouse you will have a lot of work to develop good settings. This drives me crazy , when jpg from camera looks better than RAW file (no correction).
You can show bad jpgs as good jpgs in web using photoshop express gallery (I gues it uses same engine as PS and Bridge)

Re-Seperating Color Vs Convert to Profile

I am working on several projects that are switching from overseas printers to domestic (US) printers. I have a custom profile I use, that is a variation of SWOP.
If I choose "convert to profile" there is no color shift. However, this is because nothing changes except the profile. Dmax is the same. No shifting of color value at all. (so what happens?) If I want to fit the specs I have set for this profile I need to switch modes to RGB and then re-seperate to CMYK. I know this is not good for image quality. It generates gaps in the histogram and causes a pretty serious change in colors for something that was already CMYK.
Is there a direct way to switch profiles that actually changes the color to meet the specs of the destination profile?
I have been going through and manually tweeking each image but with close to 1,000 in line I want to automate as much as possible.
Thanks,
Hartley

If I choose "convert to profile" there is no color shift. However, this is because nothing changes except the profile. Dmax is the same. No shifting of color value at all. (so what happens?)
If the two profiles are identical in every way no change may happen.
But if they are different in any way – and Total Area Coverage is just one of the properties – then a change may be imperceptible but still likely to have occured.
Just overlay the one with the other (without reseparating on dropping or pasting) and set the top one to Blend Mode Difference.

Why have all my Lightroom and Photoshop files just developped an awful colour shift? how do I correc

Why have all my Lightroom and Photogshop files suddenly developped an awful colour shift when they did not have this a week ago? I can open them in other applications and they view correctly. How can I correct this in Lightroom? HELP urgent!!

Antonia,
Probably your monitor profile is corrupt.
If you're on Windows, see here:
http://www.lightroomforums.net/showthread.php?14070-How-to-assign-an-sRGB-ICC-Profile-to-y our-monitor-%28Windows%29
If you're on a Mac, you'll need to try something similar to set your monitor profile to sRGB. NOTE: this is merely a temporary fix. You need to acquire a hardware calibrator (decent ones can be had for around $100) and calibrate your monitor with it.

Convert to Profile (Applescript)

Hi All,
I'm looking for an applescript command to perform "Convert to Profile" on my current document in Photoshop CS3. I've seen a Javascript solution in this Forum, but nothing for applescript. Any help would be appreciated.
I would also love to know how to set PS preferences so that all new docs created in a given image mode use a pre-set profile.
Thanks,
Jamie

Jamie, you can set Photoshop's colour settings by name string before opening/creating your files. You can decide how to treat profiles there. This should give you some help.
tell application "Adobe Photoshop CS2"
-- Record current settings
set User_CS to color settings
-- Apply your settings
set color settings to "Marks Test"
end tell
tell application "Adobe Photoshop CS2"
activate
tell document 1
-- Apply a colour profile
if color profile name ≠ "Europe ISO Coated FOGRA27" then
set color profile name to "Europe ISO Coated FOGRA27"
end if
-- Convert to colour profile
if color profile name ≠ "U.S. Sheetfed Coated v2" then
convert to profile "U.S. Sheetfed Coated v2" intent absolute colorimetric with dithering without blackpoint compensation
end if
end tell
end tell
tell application "Adobe Photoshop CS2"
-- Put back settings
set color settings to User_CS

Colour shifted in iPad vs MacPro/MacBook Pro 17

I had created CMYK file in Adobe Illustrator CS6 for business card/logo, etc. I placed the Ai file into InDesign CS6 business card document (two pages).
Then output the InDesign business card document as high quality print PDF. Just out of my curious, I opened the CMYK print file on my iPad 2, and noticed quickly that the colour shifted sightly on iPad 2 as opposed on MacBook Pro 17 unibody and Mac Pro - 12 core.
I suspect that it has a lot to do with CMYK color management setting on InDesign's preflight export to PDF?
Just tell me what exactly did I do wrong? Am I assuming the color shift is because of CMYK is not interpreted properly on iPad, only RGB, correct?
Thanks for some help and feedback. And please confirm this if I am assume wrong or right. And tell me why I think wrong. Or if I am right, or both ways? So I can troubleshoot in the right approach.
Look forward to hear some perspective. Have a good one.
Best, Brian

Rob,
Once again, I appreciate your insight perspective on more technical side of specific ICC profile workflow and PDF outputing workflow. I have jotted that down on my Moleskine workbook notes.
As for calibration app for iPad or iPhone or similar smartphone and tablet products, I agree with you on what you said. I don't think it is feasible thing, because Peter, yourself and I know that not all iPhone or iPad customers are colour management savvy as we are. On this regard, it is beyond what we can control over.
Again, thanks again for thoughtful perspective and discussion. Keep on coming up with more perspective and tips, I look forward to get most out of this particular more-technical workflow.
In the business card project itself has no photo file, just basic graphic design/logo - three colours.
As for digital photographic workflow, I certainly do know about ProPhotoRGB.icc profile as I use it religiously then covert to more appropriate output for web or print, etc. Of course, each specialized photo paper has the manufacturer's specific print profile assigned for EACH product. That is the whole other different story.
Anyway, thanks again for all you do...
Brian
