@Christie Photo - C&C is always welcome. Interesting fact: I have no comments on the last 5 or six image posts and in each one I indicated C&C welcome. Thanks for looking and checking in.
It figures, huh? Needless to say I don't get to view every thread, and I sure didn't want to offer uninvited criticism.
Actually, it was the thread title that got me to take a look. So often here, the term high key is used incorrectly.
I too feel the cropped version is a bit too tight. What struck me first was the lighting and model... both very nice for high key. Is that a fairly large, round reflector I'm seeing? Then I thought the symmetrical composition was an interesting choice, but wondered at the same time if a bit of motion... just a slight tip of her head might have added to the appeal.
When I saw the square crop, it confirmed what I suspected from viewing the first... that the rest of her clothing is out of key. So cropping in close as you did is one way to address that.
A nice, clean shot. Nicely done.
