There are scientific methods to compare photo quality but always exists a personal factor. In my case I love skins tones produce by Kodak cameras, but technically, is not the better.
Is there a source that directly compares the photo quality of cameras against each other? CNET and some of the other sites I have looked at review the photo quality of a camera as part of the overal review but don't provide any specific measure as compared to other cameras they review (CNET does have an overall rating--but does the Cannon SD700 produce better quality photos than the SD800? What about as compared to the top Canon A series? I can't tell from the reviews--is a lower total score the result of poor design quality or other non-photo quality performance factor?). If the sites are going to judge the cameras' picture quality (the most important component of the review imho), it seems a standard against which other cameras could be judged would be helpful--at least within the contect of the authoring site's reviews anyway. Didn't CNET used to provide a breakdown of their review score?
