Here's an image I took in Chicago of people interacting with Anish Kapoor's "Cloudgate" sculpture. There are plenty of people watching and candid shots to be taken here as the subjects are so engrossed and just about everyone has their camera out too.
In this image the foreground figure is a little dark and blends into the image too much.
As well as increasing the overall exposure without burning out the sky I have selectively increased the brightness of the foreground figure to make him much more prominent. I did this with the selection tool and created a new levels layer. I then used a mask and went around the edges of the selection to soften it.
