In a separate thread, I got excellent advice on how to tell whether the six-month old fixer concentrate I had was still good. In the course of that thread, I was advised to use double fixer bath on prints, and I have since discovered advice to do the same on film. But looking into this further, I note that some think that double fixer baths make sense in theory but add little in practice (or maybe even hurt). Rather than invite a repetition of this debate, although I welcome learning more, I wonder whether even proponents of a double fixer bath would recommend that it be used in a very, very-low-volume process such as mine. For film, I never use the same fixer on more than six 4x5 negatives, each sheet separately in the fixer, or a single role of 12 6x6 images. For prints, 16 ounces of working solution for no more than 12 5x7 RC sheets each processed in the fixer one at a time. So neither exhaustion or failure to get the solution on the surface is an issue for me. Is a double fixer bath still recommended? Thanks.
