Haarspalter, criticism is good, we can learn from it. If it's not on the subject itself, it's on the clarity of our understanding or explanation instead.

And if the Photoshop results even differ by the way we create them (as I read in BB's posting), things even get more interesting. IMHO there was nothing wrong in your experiment, but BB might like to tell us his way to get the better results out.

Oh, he just did. Well, when I performed the experiment via Save as (q=12) as well as Save for Web (q=100), I got exactly the same results both ways while using Photoshop-7. So, over time, one route got improved while the other one didn't. Great thinking. How about "know your users" instead of "know your tools" (not for BB but for Adobe). Most of the people around are photographers and artists, usage oriented instead of equipment oriented. They don't speak tech. We can help each other.

BTW: my dog prefers smell-o-graphs over phot-o-graphs :-) and tend to eat camera manuals.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
