Virtual Focus photography on the Blue Line

I took some photos yesterday of the CTA Blue Line station at Division and Milwaukee in Chicago, Illinois yesterday afternoon. Later in the day, and this morning, I decided where the focus of those photos should be, thanks to synthetic focus.

You can see a brief slideshow showing the 5 different results here. This is one of them.

Since the focus can be determined post exposure, it's interesting to see what new things I can pick out that might have been missed while I was busy managing the camera.
