Mars.

Went back to Mars; made some rookie errors but also I think I learned a couple of important lessons during the filming of my first video:

1. Strictly manual focus from here on - Nikon contrast AF is BS (not in the Notorious sense of the word).
2. Plan the shot (not in the Shooter sense of the word). 
3. Keep hold of the camera or put it in the hands of someone who you trust to get the shot.
4. Hold it as steady as possible/manufacture a steadycam rig (?)
