There is a problem in taking a shot like this; apart from the purely physical one of setting up camera and tripod on slippery wet rock, inches from deep fast flowing water. People are curious. They may even be interested in cameras. Perhaps they are taking bets on whether or not my camera and I will end up in the river. Whatever. They stand and watch and stick their heads over the parapet of the bridge. Sometimes they wave or shout things down which I cannot hear because of the rushing water. I smile and nod and wave back, probably a bad tactic. I want them to be bored. But as soon as one lot eventually wander off a new set of heads pops up. There must be a queue! Someone is making a fortune selling tickets!
Believe me; this shot took a lot of effort and a lot of time.
