I come from the world of filmmaking but I've been using Blender for years (I can't remember how many, but I know it was not even open source then).
Anyway, today my filmmaking mind started thinking about an interesting point: Blender's camera usually moves really differently than a "real world camera". It's difficult to make it move as a "real" camera without with keyframing, and even making it follow a path doesn't help much.
So I came up with a rig that tries to simulate a real camera jib (or crane). It's not perfect yet, but it's usable. I plan to work on it even more to make it perfect, but I'd like to share it with you guys anyway.
