    [poll:] does your Photoshop suffer from gammut-mapping-killer-bug ?

      Hi everyone.


      It only takes 15 seconds. There is a simple and quick way to verify whether or not your Photoshop does gammut mapping (which is needed to see accurate colors on your display).

       

      (Maybe you find it interesting for yourself, but at least you would certainly do me a big favour. If you use a Mac, skip to the bottom.)

       

       

      Here's the test:

      redtomatoes.jpg

      1) open any image with "normal" colors (e.g. red tomatoes, but any image is fine) in Photoshop.

      2) download the attached file colorspin.icm and set it as your monitor profile.* That's it!


      bluetomatoes.jpg

      *(control panel >> display >> settings >> advanced >> color management >> add... >> set as default >> apply)


      Results: Your picture can now look either "normal" (e.g. red tomatoes) or have completely absurd colors (e.g. blue tomatoes).




      I'd like to do a little poll here (so for comments, etc. please start a new thread!).

      I'd be thankful if you could briefly post your results here, that is to say:


      • normal colors or false colors
      • version of OS and Photoshop
      • are you using (1) a notebook's internal display (2) a desktop PC with standalone monitor (3) a notebook together with standalone monitor and internal monitor switched off or (4) a dual-monitor-setup ? If you are interested or have the time, you can try different situations, as they can have an impact on the outcome (that's the case for me unfortunately).


       

      I'll update this thread with a summary and an explanation, once there are enough results posted here, so check back later on. I'm trying to find out if there is a bug (either in Windows or in Photoshop) which kills the gammut mapping. There is no need to test this on Macs, as they don't have issues with this. So if you are a Mac user, please don't post your results (unless you unexpectedly suffer from this bug, too).


      So, that's it. Thanks for reading and happy testing! I'm looking forward to seeing your results
