I calibrated my display the other day and now I have this new problem. When I export an image for editing in Photoshop the colours change. I export as I always have, sRGB and 8bit PSD. I've tried a 16bit PSD. I haven't adjusted the colour profile because its been fine for 2 years so why should I?

Left is how it should be. Right has turned purple and is sRGB.
 
Have you double checked PS/LR are picking up the right profile since calibration and that PS isn't proofing or working in CMYK or something daft like that? Full reboot?

Have you checked PS/LR are using the same version of the sRGB profile? I'm sure I've read about problems in the past where they read the file from different locations but that might have been a PC only thing :shrug:
 
The thing is that the screenshot is in Lightroom. The image on the right has been made by Lightroom and hasn't been edited in anyway by Photoshop. I think my monitors calibration doesn't match sRGB.
 
Pete, email me a couple of jpg crops of the sky from both versions and I'll see how they look here. Also check both side by side in LR and PS and tell me if there's a difference.
 
I've loaded the photo into CS3 and tried various colour profiles. It seems that Lightroom operates in Adobe RGB mode. The profile for the display isn't right. sRGB isn't right. My old calibration is close to sRGB. That was manually done. Whats the point in calibrating a display only to find that Lightroom is rubbish at converting colour profiles?

Edit: Ok so Photoshop does the same converting from Adobe RGB to sRGB. This is stupid. I may as well go back to my old monitor profile as it worked. Sure its not calibrated by an expensive device but it worked.
 
Not sure what you mean by LR operating in AdobeRGB mode. It should read the profile in the image data and translate it for the output device (screen) profile. A raw image isn't in AdobeRGB or sRGB, it uses the profile for the camera. It's only when you export from LR that the image will be put in AdobeRGB or sRGB. In effect that's replacing the Camera profile so LR/CS3 will continue to translate from the new profile to the display.

What I don't understand is why in the example image the colours are different unless somehow the profile was assigned rather than converted - that's one sure way to get confusing results. In the example what colour space are used for the left/right images?
 
Yer thats what I thought. My 30D is set to sRGB. But when I changed proof colours in Photoshop and set it to Adobe RGB it had the same colours I saw in Lr. In the example the left is as I've processed it in Lr. The right is after I exported it to Ps as an 8bit PSD in sRGB. Theres something strange going on because even after converting profiles it still changes. I can't seem to keep the colours right. If I export as Adobe RGB then the colours are fine.
 
Ok lets remove PS from the equation completely. I just exported an image from Lr as sRGB and loaded it into Preview on OSX and it was like the right image in the initial post.

Funk it, gone back to my old profile. It works. Lr and sRGB in Ps or Preview looks the same. Never had any complaints from clients, prints look the same and even the photos in my book looks the same with this profile. Screw calibration tools. I'll use my eyes :)
