When I open a .jpg image as camera raw (v. 126.96.36.199), then immediately save that image as a .jpg (quality 12) from CS5 (v. 12.0.1x32) without any edits (but as a different file name), the newly saved .jpg is significantly desaturated in color when compared with the original. This does not occur if I open the .jpg without going through ACR and then immediately save (as a new file name) without any edits.
In puzzling over this, I've also noticed that when I open a .jpg in CS5 as a camera raw, then immediately open the same .jpg without going through camera raw and compare them side-by-side, there are significant differences between the two histograms.
What in the world am I doing wrong? Since it only happens when I open a .jpg as camera raw, and not in CS5 apart from ACR, I'm guessing that it has to be something in ACR. However, I have not yet been able to find a problem with the settings in ACR, and no changes I have made in ACR seem to affect the outcome.
Any ideas what I'm doing wrong, or where I might go looking?
Thanks in advance...
Check the ACR output colorspace; it's identified in the link at center bottom. If it's ProPhoto then your jpegs will look very unsaturated when viewed in a non-color managed application, such as Internet Explorer. Click on the link to change to sRGB for general email and web output.
Absolutely the correct answer. Changing the existing settings from "Adobe RGB" back to "sRGB..." did the trick. Subsequent saves show no difference. Probably the most obvious thing to the expert, but a great help to this fledgling. Many thanks!
