Aerial shooting for me started a few years back when I decided to look into attaching my DSLR camera to a remote helicopter. What followed were many years of painstaking builds and lessons learnt, sometimes the hard way.
One thing led to another and before I knew it, I was sitting for my Private Helicopters license and dealing with CASA in order to fly legally for commercial purposes.
These days Drones are the way to go, due to their technology and stability. Saying that however, nothing beats the speed of a large scale remote helicopter with a camera attached to it. Unfortunately they are a little too dangerous to have on most sets.
I have worked with some great characters over the past couple of years and am looking forward to many more in the future.
