Frankly, I've been more impressed by the real-time slide show feature than the exportable/savable QuickTime slide show. Aside from the obvious differences—artistic crossfades and audio—the real-time slide show displays full screen images with less aliasing than the QuickTime alternative. If I export the same images as a QuickTime movie and review them at full screen with QuickTime Player Pro 5, they are noticebly grainy.

The images I used were only 640 x 480 jpegs. My Apple Studio Display's resolution is set at 1024 x 768.

I've asked this question at other forums but gotten no reply: How does iPhoto's real-time slide show enlarge the images without obvious aliasing? Does it convert the images to a format that OS X's Quartz engine favors (i.e. PDF)?
