either sRGB or Adobe RGB so any photos I take with it already have a profile. Good luck Fes Win 7 64 bit, 24gb RAM, i7 x980 (6core), 2x GeForce GTX 460 Economy Notice: Due to recent budget cuts and the cost of electricity, gas and oil, as well as current market conditions and the continued decline of the economy, the Light at the End of the Tunnel has been turned off. We apologize for the inconvenience. s, what now seems apparent to me ( thanks to your advice ) - is that if I click " save " - a default colour profile is automatically assigned to the image, whereas if I click " save as ", and then save over the image, no profile is assigned ( as long as I do not tick the embed profile box )... I'm SO glad you were able to make that clear to me, as I would never have worked that out without a working knowledge of colour profiles!
