I’ll disclose the tech specs I used, and honest details of mishaps. Like when the crane head drooped like a drunkard. When focus was a foreign country. When the audio was below low. When I took too many bits of equipment to a shoot – because, yes, I’m a button glutton. And when it went so right, standing in a fountain in London’s Trafalgar Square, that I didn’t notice the temperature was below 0C.
