Log is less steep and doesn't get as flat,<br>\nwhich results in more desaturation in compressed colors <br>\nat the same threshold. Tanh is more steep and gets flatter sooner<br>\nwhich causes colors to be more saturated at the same threshold. <br>\nYou may need to boost the threshold to get the desired color appearance with tanh.<br><br>\n\n<b>Threshold</b><br>\nPercentage of the gamut to affect.

Log is less steep and doesn't get as flat,<br>\nwhich results in more desaturation in compressed colors <br>\nat the same threshold.
