I have a bunch of expired Agfa Scala B&W slide film that was given to me for free (I answered a local Craigslist ad). The film is four years past date, there are no Scala lines running in Canada anymore, and it’s too much hassle for me to do B&W reversal these days — so I’ve been developing it as a negative.
Last weekend I ran a couple of rolls through the Rolleiflex, metering as for EI 100, and developed them in Rodinal 1+25 for 6 mins at 21C. They came out looking pretty good but I would probably expose a little less next time. Scala really is just a normal B&W negative film at heart!
