The colors are natural. saturation 0 and WB as daylight in DPP. picture style 'faithful'. Pure blacks created by pulling exposure down in DPP and tons of curves work. NR using neat image. No extra sharpening. I've probably gone a little overboard with PP this time around :-) But I liked the dramatic effect. I am going to pull back a little and try some different variations.
Cropped from horizontal. I had to crop more than I like as there were other pelicans and a log in the frame.
The curved line is opposite bank. Its not really that curved. The curve got even curvy due to my curves work. Some areas became darker near both the left and right edges.
