genuinely a big reason a lot of people are fawning over this is because it has a cinematic appearance: nice composure and staging, depth of field, pleasing colour palette, the scene-setting of london buses, so on
like it's very obviously not a quickly taken candid picture, it has been very carefully composed, timed, it's highly intentional
so it's not a huge leap to then ask what story it's trying to tell, which is trying to paint a pathetic image of little old dom with his little box of belongings, waiting for the bus, like a normal person does after getting fired
all of which is completely implausible if you think about it even slightly
also notable: the photographer is not far from cummings, maybe the other side of the road, and is crouching to frame the shot from waist height. they'd be conspicuous, and not obscured -- there's no scrum of reporters crowding around -- cummings knows he is being photographed
so part of the technique of this photo is to give the impression of being candid, by isolating its subject, whose attention seems to be elsewhere, when the subject is fully aware of what's happening
also if I could say. framing this with the cenotaph in the background is a bit much
