I recently discovered Photo Story software by Microsoft and have been tinkering with it as a real alternative to MovieMaker as a digital storytelling device. It seems simple to use, has some built-in music features and allows you to get the Ken Burns effect with relatively short learning curve.
As an experiment, I created two stories: One is about my childhood, using old pictures that I converted to digital by using my digital camera to take pictures of pictures and the other story is about my three young sons.
I also recorded a song I wrote about my kids called Innocent Boy ( I used Audacity, so the quality is OK but not great) and inserted that song into the digital story as background music. The results were pretty nice, I have to say, and I can see introducing Photo Story to my sixth graders later this year (they are already tinkering with MovieMaker).
You can listen to my song, Innocent Boy song
