I've been thinking about using a pyro-based developer, and have pretty much decided on trying the Pryocat-HD formula listed on unblinkingeye.com. In the article, it says that when doing rotational development, you should use at least 75mm of developer. I use homemade BTZS-like tubes, so I assume that 75-100ml per sheet of film will be required.(posted 8276 days ago)I've also been reading on Usenet people's experiences with using the standard Pyro formula (and Rollo versions), but have had to resort to a 2-stage development since the developer seems to exhaust itself rather quickly (not sure about the Rollo version).
Has anyone tried the Pyrocat-HD in tubes? Does is behave differently than the Pyrogallo formulation in that it doesn't exhaust as quickly?
Thanks!
