Hello to all.
I´ll be bleach bypassing my negs on a upcomming project (7205 and 18) with no under exposure on the nite interiors. My doupt is regarding exposure for skip bleach process once exposing white skin under daylight ext and nite interiors (on the daylight scenes i´ll be underexposing about 1.5 stops).

Since my actor´s skin is 1 stop above N, on the daylight ext (due to the underexp) his face will be on a safe zone on the curve, now, on the nite int what is the max EI above N (spot reading of the actor´s face) that I can light him without loosing detail on his face. I´m considering 2 stops above N as partially blown out, is that a safe margin for bleach processing on my neg, 2 and 1/3 stops above N as blown out?

Second thing,
On the interior night scenes, in regards of the same white skin as described above under a very dark situation, what would be a safe "as dark as it can get" EI under N in order to still be able to fetch information from his face on a telecine? -2.0? what about considering for Vision Premiere, the same?

Thanks for your help guys, it´s very nice of you.
