Shooting with Tri-X Reversal

[Fifth Beatle]

I've never shot with Tri-X reversal before. I have a package here though that I want to use, but I need some advice before shooting (so as not to waste it.)

I need to do an indoor shot. If I use standard lighting in the house, put the exposure index on my camera all the way up, and the light meter registers F4 or F8, is it really exposing the camera MORE than that, since it is Tri-X? I believed the whole purpose of Tri-X was to be able to film under low light conditions...

I just don't want to end up with underexposed footage. I realize that a lab can push it up to two stops more, but then I'd be afraid of it being TOO bright. Hmmm...any suggestions?

F4 or F8, good deal ! Your lens will get better results in F4 or F8 compared to an F11 or F22. Remember that 200 asa is not that much : in low light situation, cinematogapher used to use 500 or 800 asa stock, & pro 35mm cameras get much lighter lens & camera transmission compared to S8 one's. What's your speed setting ? 18 or 24 ?
Last Gaspar Noe movie was only shot in natural light conditions, & the DP ,in some scene, used a 500asa film stock pushed to 1000asa.

I've shot 125 ektachrome indoors at 12fps wide open pushed one stop with good results on a H8RX f 1.3 could have been more light but it was fine.
