Great post and excellent photos.

Funny I was also thinking about writing about this idea of looking up. Recently I was taking a photo of some rooftops while out on a walk in Brussels near a popular metro stop.

A guy excitedly came over to me and told me he walks down this street for the last 4 years every day for his commute, and had never looked up before until he saw me taking a photo of something and followed my lens. He was amazed to see that there was a space between two buildings that he never noticed.

I was happy to have expanded someone's perception by getting them to see more of the world around them.
