Thank you so much for your work.
From my initial tests, I've experienced some heavy banding with the "equal" value being anything other than 0.

Re: HDR -> SDR tonemapping
I have a question. In the DGTonemap's manual, the formula for Hable is
Can you tell me what the "x" variable means? Thank you.

You can tweak it further if desired using the contrast and bright parameters. Thank you for the update. Could you please tell me the default values of "con...
