Am I the only one who doesn't care what mode random people use? It's one thing to observe what camera someone has (and since manufacturers often put the model name on the strap, it's easy for those of us to don't follow the mass market offerings closely) from afar, but getting up close enough to observe mode-selection dials? That's weird. IJS.
It's kinda obvious when rebel users came to me and asked for photography advice. Not only they were shooting in the green mode, they were also using auto focus(camera focus to nearest point.)
Would that considered as "weird"?
Of course when someone asks you for advise it isn't weird to first observe what they are currently doing. That's appropriate.
I just got the impression (for example from the post above citing a percentage) that people were scoping out random passers by, "haha that dude is on automatic, he must be a total noob," or "lol that chick bumped her dial to bulb and she probably won't notice until it's too late to get the bride and groom kissing, loser."
It's not like I particularly care if people look at the dials on my cameras, it's just kinda a weird curiosity, especially since the dials don't tell the whole story.
