Discovery through photography

I'm currently sorting through photos I took while sitting at the airport and a thing I appreciate is that both the taking of the photos and the tagging them aid in learning things about the world around me.

When I'm out and about I'm looking for new and interesting things to photograph or new ways of looking at familiar things. Then, later, when I'm home, there's learning in trying to find the name of a new flower I saw, or trying to track down where I saw a cool building or the name of an interesting sculpture
