People pay thousands for tripods that can go low, very low on the ground. Here's a more affordable alternative.
I was around a small lagoon taking photos of ducks, geese and sandhill cranes. This guy arrives with his Canon 50D and a 300mm f/4 and a 1.4 converter with tape and other stuff stuck to it. He also has a small inflatable Therm-a-rest mattress. Nigel finds a small embankment, pulls the mattress almost to the edge, the camera and lays on it.
