Happy Mistake - Behind the Shot

This was a young deer on the walking path at Sheldon Marsh State Nature Preserve.  She glanced my way as I approached but kept foraging nonetheless.  My hope was to be able to pass without spooking her and then turn to get a back lit shot. That part worked out just fine as you can see.  Of course, I didn't check the photo at the time and only noticed after getting home what I had inadvertently done.  The camera was set to DX crop mode from the day before and I obviously didn't notice the outlined frame in the veiwfinder that should have been a clue it was not in FF mode.  So, when the picture was taken I thought I included the whole head to shoulders and was surprised to see this instead.  Not being what I had expected I was ready to trash the photo when it hit me that I really liked it.  This shot is more artsy than what I had originally planned. Definitely a less is more moment.  A happy mistake.
