Below you may see 2 photos, one in color and another in B&W. The first photo was exposed in a Clack camera, using Fuji Superia 100 expired 1998. The second was exposed in a Pentax MZ-60 using TMax-400 expired 2000.
In common they have the expired date but they have more in common: they were developed simoultaneously in the same tank with the same developer. Both were developed for 30 minutes, then rinsed and fixed. After this the B&W was taken off from the tank and putted to wash and the color film underwent a blix process to remove remaining silver and finally washed together with its 'black brother'. And then both were hanged to dry.
I made some changes to the recipe I gave in the last post and, like expected, it worked well, I might have to reduce developing time from 30 to 20 minutes because both looked a bit overdeveloped.
3 g Potassium Metabisulfite
20 g soluble coffee
6 g CD4
30 g Potassium Carbonate
1.3 g Potassium Bromide
Water to make one liter
Use at 20ºC, agitation first 30s then 10s each minute for 20 minutes
