General location: Australia, South-East Queensland
The Setup:I was walking through the city on my way to taking another photo that I had planned, when I saw that there was a part of footpath blocked off. I looked up and that was it. Yes, of course they are cleaning windows, but now that I've looked a bit closer, I think it looks like they are ice skating.
The camera & lens:Camera: iPhone 4
Lens: iPhone 4 fixed lens (30mm equivalent) @ 77/20mm
Exposure: 1/2000" @ f/28/10, ISO 80
Lightroom - I cropped quite a lot, far enough that the other building reflection was cropped out and all that was left was reflected sky. I added a curve adjustment that left the light areas alone but darkened the blue parts of the sky (and reflected sky), and made sure the silhouetted leaves were completely black.
