On my external display the same image viewed in Photoshop and Lightroom is diplayed differently.
My set up:
Macbook pro running Mountain Lion (10.8.4), DVI connected NEC Spectraview 271. Photoshop CS4 and Lightroom 5. Both displays calibrated using Spectraview 5 software and an Eye one pro puck. Photoshop working space is Prophoto RGB and is set to preserve embedded profiles. I'm using Andrew Rodney's and Bill Atkinson's test images to try and figure this out.
Behaviour:
With the same image displayed in Lightroom and Photoshop on the Macbook screen they match perfectly. If I drag the Lightroom window across to the NEC it changes (as you would expect - richer colours & higher contrast). If I drag the Photoshop image across to the NEC it also changes but no longer matches the Lightroom image (cooler colours).
So, I don't really know whether Photoshop or Lightroom is displaying correctly, and whether they or the OS are to blame. I had assumed it was Lightroom as the image is more pleasing but this obviously isn't necessarily the case. What is clear is that somewhere there is a difference between how Lightroom and Photoshop are converting the image numbers for monitor display on the NEC.
Does anyone know how to find out what display profile Lightroom and Photoshop are using?
Is it possible they are both using the same profile but one is not using the NEC hardware calibration? (Seems unlikely as I assume it would be impossible for the NEC to be using different internal look up tables at the same time)
Could the OS be tripping up one and not the other in some way?
Could the X-rite software (which I don't use but is installed) somehow be interfering?
Anybody able to shed some light?
Thanks for any help,
Tom
