Weird issue here...I've been using Aperture for nearly over a year and a half and have no ran across this issue before (though I think it's more of a Preview issue). I'm not sure if this has happened because of the new version of Preview in Leopard or not (just upgraded from Tiger). When I export an image from Aperture and open it in preview, the image is noticeably more blurred. The image has been edited in Photoshop through the (edit with external editor command) if that makes a difference. The same exported image looks fine in Photoshop and when opened in web browsers. here's a screen shot with a Preview window right next to the image in Aperture http://img514.imageshack.us/img514/4048/picture1yp9.jpg any clues what might be going on here?
