I'm sure I get all kinds of strange looks when I am wandering a store or standing in line and making photos of little details around me. I find it the best way to occupy my time when I'm waiting for someone else or waiting for a line to move. Not that I care what others think either; in fact I find many people are intrigued enough to ask about what I'm shooting or at least take notice.
This was an ornament in a store shot with my iPhone. I was pretty happy with the detail after a little enhancement in LightRoom for contrast & clarity.
