Rollei High Speed film developer is a high performance developer, very sharp working and highly compensating:
Virtually any film exposed at their nominal speed has the same developing time and the RHS is one of the most universal developers on the market.
This developer (which replaces the previous R3 developer) has sharp and highly compensating characteristics. It allows a wide speed range from 100 to 6400 ISO. Dilution varies from 1+7 to 1+15 depending on film and result required-typically FP4 would be 5.5 minutes at 1+12.
Ment as a flat developer for T-Crystal Films it developeds also traditional films with cubic emulsion structure exceptionally well. The developer does not tamper with the Film emulsions grain structure. Instead it refines contour sharpness. These characteristics combine with a very attractive price the RHS has become one of the most sold film developers in Europe.
Here we have a very sharp working fine grain developer with very high compensations.
High use of capacity, high concentrate, long lasting.
