Recipe & dev times for Rollei Ortho 25 in Rollei RHC 1+4


Rollei RHC 1+4


Large Format


5 minutes, 15 seconds at 20°C/68.0°F

Recipe Id



Typical regimen of 30 seconds of agitation, and then one agitation every 30 seconds. Exposures were 0.25-0.5 seconds, f/16-f/22. I think there was a bit of reciprocity failure in the two exposures at 0.5 seconds, as they are about half a stop to a stop thinner than the other (but perfectly usable).
