This is half of my first pano attempt. The full image is from a 20D, 12 shots from a 400mm overlooking Lake Winnipesaukee shortly after sunrise. 36,000 x 2500, 494 MB in 16-bit mode.
My wife thinks I'm crazy. Then I told her that it was print 8 inches high and 10 feet wide. Then she *really* thought I was crazy.
So this is the more interesting half, from 17,400x2100
If you wish, here is a 4200x500 version, at 665KB
Playing with pano is pretty cool. But I need another gig of RAM.
