Ha ha, I read that article yesterday, really.

I don't know what you didn't understand so I can't help, but as you said it isn't really magic. I've written a pixel shader implementing the curve, so I know how it works, and it's not very difficult to at least get an idea of the process by just looking at the maths.

It only doesn't include the last scaling step.
