Rollei RPX 25

Observations: After having shot one roll of it, I found Rollei RPX 25 to be a rather temperamental film stock. Hoping for better performance for this very low speed film, what I encountered instead were highlights that were blown out and shadows that were too dark. To be sure, it delivered very fine-grained images. Its contrast levels were also very pleasing but only if my exposure settings were just right and if my choice of subject matter suited what this film stock seems to prefer. All in all, RPX 25 is probably a bit more specialized than the kind of more general-purpose black and white film I am used to shooting with.

Both these images demonstrate the extent to which this film stock does not forgive exposure setting mistakes. Left: Nikon F with Nikkor-H 50mm f/2 lens, Rollei RPX 25 film, 1/30 sec., f/2.8. Right: Nikon F with Nikkor-H 50mm f/2 lens, Rollei RPX 25 film, 1/60 sec., f/4.
