Bob,
A really nice image. I love her eyes and direct look.
From your caption, I assume the girl was doing a fair amount of laughing- probably because she had never been accosted by a stranger who wanted to take her photograph .
Which is a great attitude and indicates a sense of humor.
And she's a pretty girl without being beautiful- which IMO is always a good thing.
A pretty girl with a sense of humor? I hope the guys who meet or know her appreciate that.
Charlie
Thank you, oise and ered. I shoot RAW and convert in Nik Silver Efex Pro II. I often make two B&W iterations, one for the subject and one for the background, and combine in PS.
