[LargeFormat] Two-bath developer - advice requested (Joe Hunt)

[Pete Caluori]

Hi Joe,

I haven't used Emofin, but I have used Divided D-76 and Diafine, both are 
two bath developers.  I would not recommend using either in a rotary 
processor as you will lose most of the benefits of a divided developer.  
Rotary processing will certainly interfere with the "compensating" action.  
With two bath developers, you will want to keep agitation to a minimum and 
be gentle.  I would definitely recommend against presoaking the film.

Regards,  Pete
