That first one wasn't the sharpest I had of that day, even of that bike, but I really liked the colors and background so it was the one that got my attention while I was thumbing through them. I'd put the out of focus on that or lack of perfect panning. As for the EXIF, all I've done is host them in picasa and link to the image with a change in the size (picasa defaults to a tiny image that isn't worth viewing). I can't use picasa behind the firewall I'm on right now, but my user name is sjfooshee if you want to look, I'm pretty sure all the pics are public.

I almost always use the center for focus, that's where I'm usually trying to put the subject if it's going race speeds.
