Shoot Video! My first experiences...

Last night I went and really tested out the video capabilities of my D3s for the first time.  Shooting video is so much fun, but is actually a lot more different than what I had initially expected.  First off, it's got a few similarities to photography, which helps quite a bit.  Then, there are the differences, which can be very tough to understand/figure out at first.  The main difference being the entire approach to the shoot.  For photographers who spend days setting up a single photo, this should be no big deal.  But if you generally fly by the seat of your pants, you are in for a surprise with video!
