I am fighting an on-display and at print color shift in Photoshop CS.

Images display much to red and violet when opened in Photoshop. This happens to all images and includes, JPGs, TIFFs, and others. I can open the same images in Paint Shop Pro, Corel Photo Paint, Illustrator CS, and other applications and they all appear normally colored. Open them in PS CS and they are very violet and red. It does not matter which monitor I drag Photoshop to, the images still have their cast. I have CS on another machine and the same file looks normal on that machine. I have gone through the preferences and color settings and they appear to be identical.

All monitors on both machines are calibrated using the Spyder Pro every 60 days.

This machine is an HP Laptop with a 128mb Nvidia Video Card. I am running XP SP2 and have fully patched the OS and the PS CS program. The machine has 2GB of ram and is running a scratch disk on an empty internal 80 GB drive.

I know this has to be some stupid setting that is wrong but I can’t find it. Can someone help? Or, if you need more info or me to perform a test, what can I provide to assist your assisting me?

The print issue is not as critical at the moment but may be related. In general the file printed from Photoshop is very dull and desaturated when compared to a print from PhotoPaint or PaintShopPro using the identical file, printer, and paper combination.

Thanks

Formt he OP

From Dave

rerun adobe gamma from the control panel and follow the instructions. your calibration is out of whack.

Actually, I believe you have to make sure Adobe Gamma is disabled if you are running another calibration software like the Spyder

Also: Are you honouring the embedded profile of te images?

Adobe Gamma is disabled. It is removed from the Start Up Folder.

I am honoring the profile inbound on the image in this case sRGB from Rawshooter 2006.

Interstingly, if I turn off color management and force the file-open operation to discard the imbedded profile it comes in correctly as it does in other programs.

Here, left to right, is Preserve Color Space, Convert Color Space to Monitor Profile and Discard Color Space. Discard is the correct color or closest to it.

Discard is the correct color or closest to it.

Actually it’s not, Preserve embedded colour is the intended colour of the file creator

read that link Dave provided

I beg to differ on which is right. Having been at the scene at capture, I can tell you the sky was blue not violet. I can view the image on my Canon LCD (the Originator of the File) in Camera and it matches the blue not the violet. Rawshooter shows a file that is blue not violet. I can print the file from multiple applications including Illustrator and it matches the blue not the violet.

I have read the article posted by Dave. It is little different from Color Management Articles I have read in the past. I will reread.

Well then you have the wrong profile embedded in your image.

Cameras are both set for sRGB
RawShooter is outputing with sRGB
Photoshop default color space for working is sRGB

Any other thoughts?

Recalibrating the monitor may help (delete the old profile and create a new one)

It turned out the sRGB Profile was corrupt.

I copied it in from another machine and it cured the issue. My sky is blue again.

Thanks to all for their suggestions.
