No matter what type of photographer or videographer you are, you now have a friend to make you look professional (even if you are already professional!)
Simply go to animoto.com and upload a few pictures and videos and they will do all the work of creating a video/slideshow for you. Don't like it... simply hit remix and you will get a new version. Prices for unlimited videos start at a totally reasonable $3.
Read a review on Mashable about the service.
Check out the Getty Images case study (yes, even Getty uses it.)
PulpMotion is another great software alternative as well.
