I've done a little bit of playing with Merge to HDR and was surprised to notice that it creates files in sRGB color space, apparently without any ability to change this. It would be nice to tell it which color space to use, or to have it use the color space of the source files (or the default option in the raw converter).
Am I missing something -- can you use other color spaces or are you limited only to sRGB? I've primarily been converting RAW 20D CR2 files directly from Adobe Bridge.
This is strange, both my attempts at HDR from three images have resulted in using Adobe RGB. I have a 20D, too.
I have, however, been using File->Automate->Merge to HDR from within my CS2 demo.
I tried using Adobe Bridge to select three raw images and Tools->Photoshop->Merge to HDR. Result: Adobe RGB.
I then changed my default working space (in CS2) to ProPhoto RGB, and did another Merge to HDR from Adobe Bridge. Result: ProPhoto RGB.
My guess is that your default workspace is sRGB. You should change that, you know.
Considering another thread discussing ProPhoto RGB
, I'm reconsidering my use of Adobe RGB. I've tried ProPhoto before, but I failed in making it work for me, so I went back to Adobe RGB.
