Fuji Reala can be done with standard C41 chemicals. I have used a lot of this film together with Amaloco K54 mononegacolor C41 kit. 3:15min dev. 6:30 min Blix , 3:00 Min. wash and 1:00 Min. stabilizer (wetting agent+formaline 1%).
I know the last additive is discussible.
With this kit you have more temperature variation possible without any problem. 37,8 degrees C. but also 37 degrees C. gives no problem later on the RA-4 printing with my FEM (Wallner) CFL-4012 analyzer.
Blix and stabi can be done 38 derees C. +2/-3 degrees C.
PS. E-6 is much more critical.
