Ever heard of Ilford XP1 400? I got some but don't know what to do.greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
I came across some XP1 400 at a store but it had no instructions with it. There were FOUR bottles. Two of them were A ans B developer and the other two were A and B bleach fix. Has anyone ever used these before, and if so what are they for? And how do you mix them correctly. Thanks to anyone who helps me out. :) -John

The Ilford XP-1 *film* is the predecessor to XP-2. i.e. it's a black+white chromogenic film intended for process C41. But I suppose you already knew that.
XP1 was the first of the mono C41 films, and although it gave good results in C41, Ilford recommended their own special developer for *best* results. XP1 film was replaced by XP2 when Ilford improved it so that it didn't need special developer any more.
So what you have is a developer intended for film that has been obsolete for a decade or more.
A photo book from the mid 80s might touch on the characteristics of XP1 developer. I recall reading the above info in one of my old books (I have an extensive collection gained from charity booksales and library disposals).

That XP-1 developer is so old it's most likely dead; don't waste any time or film with it.
It's essentially the same as C-41 developer 1:1 and normal-strength blix.
