A recent scientific study found that photos with people in them are more "interesting" than those without. I want my photos to be interesting, so I've been thinking, "Where is the human element in my pictures?"
In the first photo below, from the historic flour mill district in Minneapolis, there is a person - a runner - that gives a human touch to this urban architecture image.
In the last photo, the sign "Annie's Parlour" is a bit of a human touch.
The middle photo is about nature, color, lines and patterns. Where is the human touch? It's in the shared brain architecture we humans have for appreciating nature, color, lines and patterns.
