Evaluation and comparison
by Daryl Duckworth
Efke IR820 and Rollei Infrared IR400
A series of exposures were taken with a 135mm Symmar-S at f/16 using a Hoya R72 filter.
All films were all developed in ACU-1 (1+5) for 12 minutes.
1200 dpi scan detail shows the Rollei Infrared IR400 to be far superior to the Efke IR820 with regards to grain and tonality
