Thanks Gary,

Yes, the photos were taken in "vivid" mode resulting in high saturation. That is a matter of taste. The softness is a problem. I am reluctant to move all the image sliders to 100% due to concern over page load time. Although I expect the best way to know for sure is to try it. And most likely I don't need 100% on all the images - just whatever it takes to get to 264 ppi.
