I purchased a new Drone last month (DJI Spark) and decided to see how it works in sub zero temperatures. For this I went to North Indian hill station of Manali, about 530km from Delhi. The elevation for my night stay was 7250 feet and it snowed madly overnight.
Here is the raw footage of how the video came out from the drone. Plays in max 720 HD format as this is low resolution.
