Your first impression?...Fear? If I was a stranger to this dog, she approached with that intense stare... You can bet I would be feeling some anxiety.
I still wondered about that stare...ah ha!
I realized the dog was looking at her reflection in the big shiny mirror of the W/A lense> ( 77MM cpol filter) as she approached. :O)
b.t.w. Soon after I shot this...she kisses my face all over.
