Stephen,

Gamma is meant to match your display target, so that the files look the s=
ame on any display.

Black point should be 95, and the 90% white point to taste - 685 is spec,=
 but I usually went to 710 or so. Do you have over-whites you want to def=
ine=3F

Yes, you should be going Lin to log.

BTW, check your settings by adding another AL with Cineon set to a interp=
ret from log to Lin, display gamma whatever your display is set at, 95 an=
d 685, as a print predictor.
