Missing color profile
Hello! Trying to print from Gimp. Photolabb says no ICC-profile included in image. Checking, ICC-profile is missing on some of the images. Why? As I understand Gimp automatically and by default sets sRGB IEC61966-2.1.

Question: How can I make Gimp provide a color profile on the images now missing? Tryed Google for help on Gimp help pages, understands nothing, only to me contradicting and insufficient information for my problem. Please help someone! Gimp 2.8.

Below image shows Color management settings i my Gimp (Swedish), shold be as default. Sometimes an ICC-profile is included with the image, sometimes not. ??

RE: Missing color profile
try
"In GIMP click Edit > Preferences > Colour Management > change the File Open behaviour to "Keep Embedded Profile". "

If you get a message pop up when importing images that ask to convert always try the "keep embedded profile" option.

RE: Missing color profile
Thanks for fast reply!

Have changed the setting to keep embedded profile now. But, how to do with the images with already missing profiles? I can't edit them all over from the start with the profile keept from opening, that would be a to massive work. Can I add the profile now to the already edited images in some way?

Have read that Gimp really doesn't like that one is messing around with color profiles in it, not changing the default setting at all sems to be a reosonable way to aviode future problems according to movements of the original color profiles adress in ones file system (I most probably sometime will move my color profile in my computer, and I most probably will not remember that it should not be moved once used in Gimp).

- Hopefully this won't be so a problem the poster of this information on the net means?

Theoretically, you should be able to, using the previous mentioned technique for the missing color spaces. Then it comes down to the format you save it as (one that will retain the colorspace)

The 2 big questions is where are these images coming from? (RAW from the camera? after saving from photoshop? after saving from Gimp?) before you took it to thephotolab.
and
what format/extension are they in? (.psd, .xcf, .jpeg, .gif, .png? other?)

Something to try:

Open the image your native photo viewer, then copy it and paste it in a new gimp document(gimp new file is default sRGB)

In Gimp
"File > New"
after pasting as layer or naming the floating layer...
"Image > Fit Canvasto layers..." (if its cropped)
Check "Image > mode" ensure its on RGB
Then export as...

Get back to me when you can Smile

RE: Missing color profile
Hello again!
Problem solved. I guess it all had to do with Gimp stripping of the embedded color profile when initialy opening (this without Gimp asking if do so) the exported JPG file out of Lightroom, converted there from RAW.

I downloaded the sRGB-ICC profile of my choise (http://www.color.org/srgbprofiles.xalter), installed it in Windows and converted the stripped image to this profile using the Gimp dialogue Image-Mode-Convert to colorprofile.

Now I have learnt a lot about color management for printing and I'm ready to print :-)

Thank's for you helping me sorting this djungle out!
