I often have to be patient and wait for a frame that I know will present itself, sort of like a National Geographic photographer in the wild. Sometimes there are other factors too, like people or cars, etc. between the subject and the camera. This one is at the Musée d’Orsay in 2015. Everybody wants to do selfies in front of this famous clock. I saw this couple just standing there, looking out, but there was a constant flow of people between me and them… until that one second.
