Interesting you bring this up. I was just think of summer and planning some stuff. I have shot out of fixed wing, Helicopter, and Balloons. I did that in the old days with film. I directed a shoot with movie cameras over Teton by Chopper in December way back when. I carrier two films camera. We had doors of and flew sideways a great deal. My camera man stood on the skids most of the shoot. My still shooting was with Canon Ftb/28mm. This documented the shoot. We also went into the Yellowstone Park and shot the Grand Canyon of the Yellowstone.

Watch out for bumpiness over mountains. Good way to get a black eye of swollen lip.

Have fun.

Here is what I found and it may applies today and to you but remember 30+ years ago with film still and movie camera.

It was so cold adding in wind chill from flying sideway that the movie camera ate batteries and the actually quit running to the point we had to stop and warm it up. The scenes were much more lite than I thought. It seems that the higher you go the more light you have. This was specially true of shooting from Balloons. The chopper I was in had lots vibration. It's my understand it's not that way now. With dig I can now crank up the ISO.
