Hey guys first time post so please go easy! :)

I am shooting a movie on 16mm with a Bolex for my mid-level production class. I am using Kodak 7266 Tri-X Reversal Film. I forgot to change the ASA reading to 160 for my indoor shoot today, and still had it set to 200(which is what it should be set for outdoor shooting.) How will this effect how my footage will come out? Will it be salvageable? I'm worried because I'm only alloted 10 rolls to work with and if I have to re-shoot the entire indoor sequence I could be screwed.

Any help would be appreciated.

You've underexposed that scene by a third stop. A third would be pretty negligible on negative but it will be pretty noticeable on reversal. It won't be a wash unless you were already riding the edge of darkness.

Do you think I should push it one stop in development to be safe?

I wouldn't push it. You'll be OK with a third under. I shoot all my color reversal stills a third under to get better density.

Alright I'm sending the footage in and I'll just have it processed normally. Thanks so much for your advice.

Like Chris said, you should be OK. It all depends on how you lit it and if you exposed it properly. 1/3 under is not the worse thing you could do.
