not sure if this is what you wanted but I had a go
What I did was use adjustment layers to put 2 black and white adjustment layers on then set one for a nice overall look and one with (if I remember right) the red and yellow settings right over to thr right so just the dark area on the right bottom is brighter.
Then I used a brush to paint on the mask out so the nice overall B+W effect is seen for all but the bottom right
Is that any help or not what you meant?
