Clicking photographs also appeases the anxiety which people develop when they are in an alien place. They can take pictures: they have something to do! I have learnt to be more respectful, less leery of "tourist traps". These "traps" stop the tourist from climbing over the fence of some of Shimla's (or indeed Rome's or London's) prettiest places to take pictures of people in their natural habitat!
I have posted a set of photographs of people taking photographs. My intention is not to poke fun at them. Indeed, I feel a genuine affection for them, for do we not belong to a brotherhood which is trying to capture a neat slice of time, choosy, chancy and temperamental as that may be?!
