On my way home from a gallery shoot last evening I had my camera set to 1/15 because I wanted to play with light and motion blur.
When I arrived at my bus stop I hadn't seen anything interesting, so I was resigned to head home as I was wiped and loaded with gear.
A garbage truck across the street doing a 180 was the most interesting thing I had seen on my walk.
So I brought my camera up and waited.
There was a moment where the truck slowed, the man reached out and a car whizzed by and my brain said 'now.'
Outside of that I can't profess to being conscious that there was a light behind the waste worker giving him a halo which made this an image.
