I've been reading up on Willie Beutler's formula. It is posted here in the recipies area and gets mentioned quite often in conjunction with the "new Adox thin films" (ca. early 1970's). Looks like a simple formula that is inexpensive and easy to use, has good keeping properties, and produces consistently good results. So, what's the down side? Does it work OK with continuous agitation (i.e. in a JOBO) ? Willi Beutler's Part A: 1000 ml water 10 g metol 50 g sodium sulphite Part B: 1000 ml water 50 g sodium carbonate (dry) to use, mix 1 part A + 1 part B + 10 parts water.
