I did a backup right before I did an erase and install of Leopard. Right afterwards, I did a migration. So, for my pictures, I have the original copy on my backup harddrive, and a migrated copy on my now Leopard machine. So, I'm playing around, and I pulled up some pictures using iPhoto and I get a strong feeling what used to be sharp looking pictures, are now a tad blurry. What I'm saying is in Tiger, my pictures looked sharp. In Leopard, the pictures do not look as sharp. For kicks and giggles, I did a side by side comparison between the pictures and there was a small noticeable difference. I have NO idea if anyone else has experienced this, but I have photography as a side hobby and this is what I saw with my eyes, and yes my eyes work fine. 1.5GHz, PPC G4, 1.25GB ram. So very extremely strange phenomenon.
