Yes, the Dimage Viewer software (which I did not get with my cam) has color correction utilities built into it. But I think a simpler explanation is the Raj people used PS for not only transfering the photos to the computer but also for color correction.
11A, I'll send you a sample photo from the Dimage X, you run it through PS Elements and then we'll look at the exif and also see if any standard color correction yields similar results as the Raj pics.
