Just found a great effect that someone has tried by stitching about 200 images taken over a 1h20 shoot together. From his flickr page, the stats are:

• All shots handheld except for about 8 shots with tripod



• 256 images taken
• 200 or so images used
• 270 or so layers created
• 1.6GB original image size
• 1h20 shoot time
• 16h or so in total

I’m going to try this as soon as I find a scene that would live up to that kind of punishment
