This process is designed for the Commercial Reversal processing of Filmotec Movie film. But should work well with any modern B&W film. You will need to experiment with the first development time and EI to find the best combination for your purposes.

The First Developer & 2nd Developer are identical except for the Potassium Thiocyanate in the first.

..of all these public/published recipes posted here, this is likely the best one to start with. Modifications should be made depending on the film used.

Reversal processing is with the effort especially if you are scanning the film.

Why?

[Ian Grant]

It goes against all DW's own recommendations in a forthcoming publication where he advises not to use a solvent in the first developer, thiosulphate or thiocyanate. However the film manufacturers have rather more expertise in the field of Reversal processing, so this a modern modern/current 1st Developer recommend by Filmotec. However it's remarkably similar to ID-62 (used 1+1) + Thiocyanate (instead of Thiosulphate), plus additional bromide instead of Benzotriazole.
