ok bear with me..
before reading this thread, my Camera Raw, photoshop, and camera were all set to sRGB workspace.
after editing my pictures, on "saving for web" there is an option to compare the edited photo and the saved photo side by side. on sRGB, there is no difference in the two images (i suppose this is because sRGB workspace was used throughout the whole process from camera to ACR to pshop).
after reading this thread, i tried setting my camera, ACR and pshop to adobeRGB.
after editing, "saving for web", and checking the "convert to SRGB" option, comparing the two images side by side show a difference in colour, contrast and saturation..
is this normal?
