Not strictly aerial photography, but instead having to do with videoing models in flight, the improved hat cam:
If I keep the red loop on the object of interest, it's more or less in the center of the frame. Actually, it needs to be my dominant right eye doing the positioning, not the left, which can get a little confusing when doing something complicated like flying an RC plane

. It's going to take some getting used to... The hat has to be put on exactly the same way it was on when the thing was set up as well, but preliminary tests indicate that it's way better than just trying to remember to point your head towards the plane. The cat thinks it's a hoot anyway
