How to develop film in expensive beer

[Bryan]

That bastard! Well, I got the idea from someone that was developing prints with beer.  Tri-X is one of the few films that has given me trouble with beer, maybe I need to turn up the heat to 90.

Sounds like a delicious gose so I'd rather drink the beer than develop film in it!

[Francois]

I must admit that I'm pretty impressed. I wonder if they reverse processed the film?
Got me thinking about something. Does anyone know a barman?
You can always ask him to dump the leftover beers in a bucket to make developer. I know it's pretty gross but it is free waste material that could be used....

That's a good point! From the diagram in that post it looks like straight negative development. Must have been scanned/inverted/converted to a movie file in software?

It's Tri-X reversal film, not negative film.

[Francois]

So it automatically reverses like direct positive film... I guess.

It's Tri-X reversal film, not negative film.

I thought even B&W reversal film needed a separate reversal bath? But I know nothing of B&W reversal film, so never mind me.

[Francois]

I thought the same too but I must say I know nothing about cine film...

[Bryan]

Tri-X reversal can be processed both ways, there is a bleach step for reversal.  The process they show for this beer is negative.

[Francois]

Pretty much what I was expecting.
But still it's pretty cool.

I never had a chance to try b&w slide film.

I have a couple of rolls of super low-ISO direct positive B&W slide film I still haven't finished shooting or processing yet.

I keep thinking I want to shoot it and develop it in a monobath while I travel, but it's ISO 0.75. It's easier to shoot paper negs. 

[Francois]

At 0.75 ISO, you definitely can't use it to take pics of the kids running around 

[Indofunk]

ISO 0.75??? And I thought I was crazy for shooting at ISO 6

[Francois]

So far, my lowest has been ISO 3 Lith film.
Second lowest is ISO 50, and I feel that's really fast.

I've got a roll of Rollei RPX 25 sitting on my desk right now...
