You can’t get this kind of shot with a telephoto lens. Nuh-uh.
There is something about getting up close that squeezes the depth of field to its barest minimum, isolating your subject and potentially capturing a rare moment of interaction that would otherwise be missed at a distance. People rarely notice, and if they do like the little girl in Venice above, the moment is fleeting and attentions are soon distracted.
Miss Pink here was too busy eating, and hanging about waiting for whomever she was waiting for to notice my having followed her down Oxford Street to get my shot. Would any of these people have really cared if they knew I’d caught them on camera? I doubt it. Or perhaps, would they secretly have been pleased that for a split second they were noticed and given a moment’s fame? Most likely. But the moment is brief, as quick as a blink, and how many times in a day does the average human blink? (You don’t actually need to work this one out, although I know some of you will try).
Wanna be a do-gooding, sensible super-hero who’s generally popular with everybody?
Then take up flying lessons…or knitting. Knit yourself a cape or something…
