Haha, I was happily snapping away at the scene until he saw me, got up and walked away. This was at the moment of him getting up, hence the constipated posture .
In post processing, I changed many aspects of lens corrections to make everything look straight. I clicked auto button on the tone panel, I then increased the contrast by setting the point curve of tone curve to medium. That was all I did (to this pic and to most of the photos I posted).
Excellent Jim. Another of your two-for-the-price-of-one shots. A beautifully clean shot of an interesting wall and window and then 'him', timed to perfection. Nice.
