Not sure.Exposure in terms of linear scaling should not affect color saturation, at least not without further adjustments on the top.But it does at times:Peter
You are correct. Hue twists in the newer generation of Adobe profiles have been widely discussed and there is even a tool for removing them. See this post and the referenced thread on the Adobe forum as well as a recent thread on LuLa. It would make sense to adjust luminance in a linear fashion before correcting color with look-up tables which introduce hue twists.Regards,Bill
