MYSTERY

"Anything that is kept secret or remains unexplained or unknown"

Of course, if someone wants a portrait, they want to be seen!
But why not have some "mystery" shots as well?
I can't explain why I am so attracted to this type of photos.
Maybe because it lets you more room for imagination? To build a story in your head?

Anyway, it's stimulation for the brain (at least for mine).
