Pigeon in an apple tree

I've been investigating lately how I can fix some picture problems by looking at and modifying the Hue, Saturation, and Lightness Maps that Paint Shop Pro can produce. Sometimes the maps themselves are interesting.

This is a pigeon in our apple tree this morning, as seen in the Saturation Map which I reversed (into a negative of itself, though more natural than the map had been) and then tweaked the tonal curve of to get something more pleasant.

Not a *very* traditional b&w, but at least interesting.
