[Leica] Technical Question Film Processing

[len-001 at verizon.net (Leonard Taupier)]

Hi Jim,

I don't know if anyone addressed the streaking problem. Is the  
streaking like water spots? Or is it more like streaking in the  
negative itself caused by the developing and fixing process? How do  
you agitate the developer and for how long?

Next is the Phoflo. It is not a wash. It is a wetting agent used to  
eliminate water spots in the drying process. A 30 second dip in  
Phoflo is all you need.

Also I would not dry film in the basement unless you have a finished  
ceiling. Walking overhead will release dust as you walk above.

Also are you using distilled water for your developer, fixer and  
Photoflo? Any contamination in your Photoflo caused by particulates  
in the tap water will cause what looks like dust. The Phoflo solution  
is what remains on the film while drying.

If you still have my number give me a call or pm me.

Len
