Sodium Thiosulphate as one shot fixer for Jobo processed film?

Tom Kershaw · Mar 15, 2019

I've been undertaking a major tidy and reorganisation of my darkroom recently and have found a large container. While I realise the advantages of rapid fixers, is there any reason why a one shot fixer made up with sodium thiosulphate wouldn't work successfully for one shot Jobo processing?

No, as long as you fix and wash long enough.

Be careful with T-grain films and their requirements for more fixing.

I use Photoformulary's TF-5 most of the time but I also use a lot of home mixed Sodium Thiosulphate as well. Most of the time I use it on my Arista EDU films but I fix for about twice the time and wash for a longer period. Actually I kind of prefer using the Jobo rotary drums on my old Unicolol Drum Roller with this type of fixer. The extra times required are less of a headache that way.

But I always use TF-5 for t-grain film since it is harder on fixer to start with.

I was thinking more of use with traditional grain films. I must have got the Sodium Thiosulphate in for a particular purpose I've now forgotten.
