I’m not sure what he’s trying to achieve.
Either he’s trying to balance the camera (a Canon 7DmkII with a 16-35mm L lens) like a Steadicam using the tripod being the counter weight or just plain and simple he can’t be bothered closing the tripod.
I wonder if it works.
Could I use my tripod at arms length and use a small open tripod to counter-weight the movements?
