My receptionist got married yesterday and somehow I got recruited to do the slideshow. FotoMagico makes it so easy. You literally drop the pictures in and the "Ken Burns" effect is done for you. This used to take me a lot of time in iMovie. I don't really care much for the way it incorporates music. It should automatically adjust the slide length to match the song length but for assembling the pictures it makes it too east.
I had the slideshow done when I showed up for the wedding but I did drop in one picture of them at the alter at the end and that one got a lot of response from the guests. The funniest part was the "official" photographer (who also drives a Mac) practically assaulted me and wanted to know the name of "that program."
