Ah, right. Haven't been in Shake in a while. I sort of remember that Ngamma was negative film stock gamma, but never had reason to tweak it. I'm guessing that Nuke's LogLin node's 'gamma' knob is the equivalent. But it doesn't provide separate r, g, b control.

Maybe post to the Foundry's listserve and ask what the exact math is behind the LogLin node. Or, roll your own using an Expression node and the Cineon docs: http://www.cineon.com/conv_10to8bit.php

Hope that helps
