I always set the colour space in my camera to adobe RGB and shoot in RAW. Then, when I develop images with NX2, at the last stage when I save the image into a jpeg file I switch the colour space to sRGB. This works fine and I have encountered no problem.



But recently when I try to do the same thing with Photoshop CS5, I encounter a problem. I develope the RAW image with 16 bits/chanel and proPhoto RGB colour. Then, after I finish it and prepare to save the image into a jpeg file, I first switch the 16 bits/channel to 8 bits/chanel and in the menu View->Proof Setup->choose the "Internet Standard RGB (sRGB)". Then I "Save As" and choose the format "jpeg", then a dialogue pops up with an option for "color", which contains two oprions: (1) Use proof setup (which is in grey so cannot be checked); (2) ICC profile adobe RGB (1998) (which is checked by defaut). Then I "de-check" the adobe RGB option (2), but (1) is still grey. If I save the file then I guess the file is saved in "proPhoto RGB" since the saved image is displayed with wrong colour in some image viewers.



Can sombody tell me what is the correct way to save the image in jpeg with sRGB colour?



Many thanks,
