As with so many mediocre tone mapping functions, `tonemapfarbman` overemphasizes the red channel. I have seen better (without parameter tweaking).

The 2018 solution would be to just train a neural network to do the color mapping and call it a day without ever really trying to solve the problem.

Hell, it would probably work insanely well.

What would you train it on, without already having an algorithm you consider 'good'?
