He either stood too far away, behind them, too far away and behind them, or pointed the camera mainly at the floor. This is a classic case of a boy attempting a man’s job.
This isn’t really “taking a photo of a booth babe” – it’s stalking a woman going about her everyday business in the street. Look, that’s her suitcase, not an NVIDIA promotional carrier bag.

They’re far away, and the thing they were doing has finished.

What if she turned around? It’s one thing going up to a woman and asking if you can take her photo – that’s quite normal at a trade show. But taking one from behind and quite far away just makes you look extremely odd.

This one sort of delivers, but we’d need to see the front of it before coming to any firm conclusion.

Classic shy man photo. Don’t want to lift the camera up too much, or someone might think you’re actually taking a photograph.

Far away, from behind. 2/10.

Not only is this far away and from behind, the angle of the shot suggests he’s even up on a different level looking over the edge! This isn’t much better quality than you’d get from just zooming in on the show’s location on Google Maps.

Really far away. And with a man in the way for added safety.

They’re not even on duty! The biggest trade show faux pas you can make is attempting to interact with the booth staff while they’re on a break. They’re allowed a break because of laws, and would rather spend it smoking and slagging people like us off, not talking to us and trying to stop us taking photos up their dresses.

Finally – a great shot. That man has stopped in his tracks just to stare at the front of a woman. He may even have his cock in his left hand, such is his unashamed ogling.
