[pure-silver] Re: Diafine

Hi Craig,
That's one of the formulas I pulled off the 'net after my search with Google. The formula is from Patrick Dignan's book "Classic B&W Formulas"
I have 400 ft of 16mm Microfilm, Fuji Super HR, and I've been told by several people who shoot in 16 and 8 mm that Diafine is the way to go with Microfilm. So I want to find out for myself. Developer's that are dedicated to microfilm give a very contrasty neg whereas Diafine gives the neg tonality and enables the microfilm to be used for pictorial purposes. 

I have 400 feet. so might as well play around with it.

Thanks for taking the time to copy it out for me; much appreciated.

Cheers,
Bogdan

Here's one from my files.... Supposed to be a Diafine equivalent, but I've not tried it. Personally, I had mediocre results with Diafine and never pursued it after that but many people have excellent results with their materials and techniques. If you have the components, it might be worth a try. 


        
        
Solution A      
        
Dist Water      750     ml
Sodium Sulfite  35      g
Hydroquinone    6       g
Phenidone       0.2     g
Sodium Bisulfite        6       g
Water to make   1000    ml

        
        
Solution B      
        
Water   750     ml
Sodium Sulfite  65      g
Sodium Metaborate       20      g
Water to make   1000    ml
