Mistake with Adobe Stock images and InDesign - Profile mistake

[ChristianK-Fr]

Hi all, 

I 'd like to understand what is wrong with this : 

Problem : when your InDesign document color setting is Adobe RGB 1998 for RGB, and you import Adobe Stock image ( images are in sRGB profile), it give a wrong profile to images (it give document profile), so when it convert to CMYK destination, it make wrong conversion, because it give wrong source information.

If you open image in Photoshop with preserve embedded profile ( sRGB), and made Save as new document, with embedded profile check ( so sRGB profile is the image profile), and you import this new image in InDesign, image have the right profile ( if you set the links panel with icc profile, you can see it).

This is my mistake I'd like to understand. Why original Adobe Stock image have issue when import in InDesign, sRGB profile image isn't assignate ?

You can see below screenshots explain how I made the test. 

Thanks for your help, 

Christian

Forget to upload finally the result after export PDF in CMYK : you can see difference in colors beetween import Adobe Stock image and save as new image : effectively, with wrong profile source information, conversion made wrong colors.

A good rule of thumb for all stock photo sites unless otherwise stated these images are always in sRGB.  If for some reason you get one without an embedded profile I also look at the Colot Management settings to make sure they are set to preserve embedded profiles.

Thanks for your answer, effectively I set my color management to preserve embedded profile, and that's my mistake, it didn't see the profile effectively embedded, I check information in Adobe Bridge.

It's not your mistake. People failing to embed the profile is a ubiquitous problem, not specific to Adobe Stock. It happens everywhere.

If you source images from outside, you always need to check that there is an embedded profile, and if there isn't, assign the one that appears to be the correct one (or close enough).

Of course, Adobe Stock should enforce this as a strict requirement, I agree with that. Untagged images are always a problem.

Thanks for your answer, I'm agree with you, but look at the images, open with Bridge and see data : the ICC profile is tagged, that's my mistake....

Why InDesign didn't see it ? Strange isn't it ?

[D Fosse]

This is where you should check the profile in Photoshop:

-or in Bridge:

I frankly don't know what that entry in metadata under "raw data" refers to. It may well just be the setting in ACR as the file was originally opened.

It does seem like the profile was missing, that’s not good.

"If you source images from outside, you always need to check that there is an embedded profile, and if there isn't, assign the one that appears to be the correct one (or close enough)."

that’s right, and it means (on a calibrated profiled display) go to edit / assign profile and try assigning, say Adobe RGB or sRGB, one of those will make their image look right, once it looks right its safe to assign that profile. 

I really do wish that the days of supplied images without embedded ICC profiles were long gone, but it seems prehps that’s too much to wish for

I hope this helps

Thanks for your answer, but I think you misunderstood the issue : profile is in image. InDesign didn't see it.

And of course I check, and it's because I scheck that I see these issue. Each answers are about missing profile but it's not that : profile is in image ! Make the test, download the image and tell me what's happen ;-)...

Of course I could change the settings in InDesign and set working space RVB to sRGB, but it will be not resolve the issue/bug you see what I mean ?

Hi ! 

I check image with other tools, and effectively there's no profile embedded iin image, so InDesign give the document profile. So why when I open it in Photoshop it tell me there's a profile ? and same information in Adobe Bridge ?

 Thanks !

If I understand you correctly, the problem is that InDesign thinks that the images don't have an embedded profile, and then assigns Adobe RGB, which you have set up as a working space, causing a color shift.

I have never experienced or heard of this before, and the only reason I can think of is that there is something wrong with the embedded sRGB profile, or that it hasn't been embedded properly, or that the files are somehow corrupted.

I suggest that you set the RGB working space (temporarily) in InDesign to sRGB, which you have indicated does fix the problem.

Like in Photoshop, the working space is a fallback for untagged images, and these are much more likely to be sRGB than Adobe RGB. Note that any RGB colors/swatches you create in InDesign will now be in sRGB.

I get the impression that resaving the images in Photoshop also works, but I'd be careful with resaving jpgs.

The jpg format uses lossy compression, and every time you resave a jpg, image quality deteriorates.

Examine the images at 100% view to see if the quality is acceptable.

Alternatively, to prevent quality loss, save the jpgs as Tiff or PSD immediately after opening them in Photoshop.

Even easier and AFAIK, one can 'assign' a profile, even to a JPEG without causing a re-save (?), use Automator and the Apply ColorSync Profile to Image, make a Automater "Application" with this, drag and drop the images on top.

Could be EXIF data, an EXIF profile tag? Yes, there should be an embedded ICC profile (ideally). But some strip this out to 'save' a mere 4K of data (I suppose if you host millions of images, that adds up but not a great excuse). 

In Photoshop's preferences, what do you see on your copy:

Hi Per, thanks for your answers, 

Here is my Photoshop's preferences, 

And to prevent re-save jpeg or made Automator, I set InDesign preferences to sRGB, 

Thanks for all yours answers very interesting !
