Hi, I'm fairly new to photoshop and raw images; and unfortunately I can't get past this major stumbling block...
If I open certain cr2's in adobe camera raw (to get them into photoshop), then they look horrible - they seem to have lost color depth. Some cr2's seem OK.
Actually I've just done some more experimenting and it seems my problem isn't just adobe camera raw... if i view cr2 in irfanview they look fine, and if i save a jpeg/tiff/png,
then view again with irfanview they look good, but the jpeg/tiff/png viewed in windows photo-gallery, or picasa-viewer, or photoshop look horrible; and if I open cr2 in photoshop and save as jpeg it also looks horrible.
Here is an image... it looks fine/good when viewed with irfanview - looks just like the original cr2;

but when opened/viewed in other tools (e.g. photo gallery, or photoshop) it looks bad - the fringes of the hair and eyebrows are orange and there's a lot of dithering.
This 'bad' image is what i get if i use adobe-camera-raw and save from photoshop.
here's the bad image: I got this by doing a screenshot of the png I opened in photoshop:
I know this sounds weird... I get very different image depending on which tool I open it with. The two images above are the same image... one rendered (correctly) with irfanview; and the other rendered apparently incorrectly with photoshop/adobe-camera-raw/picasa/photo-gallery.
Oh, and if I first convert to dng with DNGConverter then I still get the same problem, but also get a lot more dithering introduced.
actually this all seems to be due to a bad color-profile installed for my monitor.
