Of course, you two were posting at the same time as I was cropping etc.... thats life. I take your points, as you see from my efforts as well.
Bill, your increased vibrance works well, and that's exactly how mine looks on the laptop. I have no idea why it does not translate to the screen. I can only think that in fact yours is even brighter than I am actually seeing it, because mine looks washed out, compared to what it looks like here. This, no doubt, is down to the fact that right now I am not using that external screen I bought for just this reason... editing photographs. Oops.
I'm going to recalibrate my MBP screen and see if it makes a difference. But... surely it should not, between here, in iphoto and PS, to there, on the web... seems insane to me.
[edit] after a recalibration of the screen (I still had it set on the printer profile. argh) I can see how much brighter yours and Lukes are, Bill, than mine.
