We were engaged to shoot aerials in the Swiss Alps for a new product from l’Oréal. We spent 2 days on the summits at 2600 meters above sea level then at 3500 meters in order to have a panorama on all the chain of the Alps. The weather was with us, big blue sky and especially no wind, which is rather rare on these summits. We did not encounter any particular technical difficulties except of course the cold at the end of our fingers, our drones were all equipped with High Altitude propellers because the lift at more than 2500 meters is more difficult. We are very happy and very proud to have been involved in this great project.
