I have been working for the BBC today doing some aerial filming using drones on the mountains of Snowdon and Crib Goch. I was filming Caradog Jones, the first Welshman to climb Everest, and he was a thoroughly nice bloke so I had a great day out and got some stunning shots using a combination of the Phantom 2, Go Pro Hero 4, Panasonic GH4 and DJI Ronin M. I will add a link to the program once it has been broadcast.
