Something else you can try that Kevin Sullivan shared with me is that if  
the Zia doesn't print out to the extent you want try using regular Pt/Pd  
developer.  It will complete the process.  As the Zia is very humidity  
dependant to complete the chemical reaction as a POP material, this is a  
reasonable solution (no pun intended).

Thanks,  Loris,
How many drops, Loris, per drop count? I have glycerin I could try.  

Anything to make Montana's lack of humidity work!

Good to know  about the AFO because mine is old, too and I was wondering if 
I should  worry.
