What is the most difficult part of the documentary "Aerial Photography of China" in the second season?

I think the hardest thing is shooting. Photographers have to shoot at high altitude, which is very hard and definitely tests willpower and obsessive-compulsive disorder. Here I want to say thank you to these brave photographers! Thank them for bringing us such a beautiful China.

The most difficult thing to control in aerial photography is the weather. Whether the weather permeability and light angle meet the requirements of aerial photography, these are all things that need attention. Especially for the shooting effect, we will choose sunrise and dusk, and the light in these periods will be stiff for high-altitude shooting, which requires softer light on cloudy days.

Then there is the special airspace aerial photography that needs to be approved, and the approval time is just in line with the weather factor I mentioned above. This is the right place at the right time, and everything is ready! Besides, for some remote places, it is troublesome to get water and food, and some places are even easy to get lost.

I pay more respect to the photographers and thank them for their persistence and efforts. They certainly experienced many difficulties in this process, but they didn't give up and insisted on bringing us such beautiful works. Thank you.
