There were cars there? I wanted to have a look at the new Mitsubishi Lancer Evo, but didn't notice it there.
Seriously, though, the statistic is that 50% of models can spot a single lens reflex camera from a mile away. For the above shot, I was in a crowd of people milling about in the general area 10 metres from the elevated section (this shot is a slight crop) when a small gap appeared and I raised the camera and fired in one quick motion. Yet two of the four girls spotted me immediately, a nondescript dude in a big bunch of people... with a DSLR camera.
In general, they're a great bunch of girls, I chatted with Lauren B. on the Holden stand for maybe 15 minutes, an extraordinary green-eyed blonde from Jersey. Get this -- they're actually paid to talk to us!
You've nearly as much an eye for cars as you have for street shots. Those are great photos, Kev, I could not believe how busy the show was so you must've been really patient to get them without the throng getting in the way -- or maybe you've got bad BO and a mad look in your eyes! (j/k mate!).
