28mm actually, but it is medium format lens, so it is the equivalent of 19mm. This shot took almost two hours to capture. The athletes in the shot had to time their jumps precisely to land in the right pose and the right part of the image. To do that, we had to see each jump individually, then with two, then three, then all four of them. When we finally got it, it was a great feeling.
I also had secondary lighting from a couple of strong (500WS) flash units on light stands positioned behind the concrete walls.

Fascinating composition - assuming you used a 15mm?
