Hi All,

 

I currently want to shoot some 16mm Tri-X for an experimental film I'm making. I'm going to do bucket processing, but I want to bucket process as a negative.  I keep reading in onine and in other forums here that if you shoot reversal film and want to process as a negative you need to overexpose a little bit when filming. Since I'm shooting this in daylight and the EI for daylight is 200, I was wondering what I should rate my film at. Should I overexpose by 1 stop or 2 stops etc. or would processing it for longer work also?

 

 

Thanks for the help!

Don't overexpose it too much, even when you run it as Negative it retains the reversal character, I rate it about 2/3 of a stop slower as Neg but that can be compensated for in developing too if you want to rate it as normal.

Yeah, I usually just rate it at 200. Tri-x as a negative is going to be contrastier and grainier than it would be as reversal, so sometimes I'll overexpose a stop and pull process a bump. But honestly the difference is pretty minimal. I can't recall if I've ever tried two stops. I feel like I must have at some point.

Just for reference, here's some tri-x I rated 200 and pushed processed about 1 stop to compensate.
