here's the 2nd new film from Maco/Germany, the Rollei RPX 100. Like the RPX 400 it is made in Europe, a classic cubic emulsion with 100 ASA boxspeed and shall replace the old Agfa APX 100. To say first things first: this film in my opinion is far better than the old APX 100 and much more than a substitute. The RPX 100 is a very fine grained, easy to handle and easy to develop film with excellent tonality. Speed in Caffenol-C-L is enhanced and grain is still very small, almost invisible. Again Maco brought us one of the best classic emulsions available today, it could turn out that this beautiful film will be my first choice for medium speed films in the future. Available in the US as the RPX 400 about end of April, 35 mm earlier than 120 format. Here we go with progressive exposures from EI 25 to 400.
Semi-stand developed in Caffenol-C-L, 0.8 g/l potassium bromide, 20 °C, 70 minutes. No presoak, agitation first minute continuosly, then 3 times at 2, 4, 8, 16 and 32 minutes. Perfect even development, very fine grain. EI 25 to 100 are overexposed, EI 200-400 is perfect for scanning purpose. Maybe a bit too contrasty for silverprints, so I would reduce the dev time to about 40-50 minutes at EI 200. I have no doubt this film will also perform very well in Caffenol-C-M at about 10 minutes developing time. Look at the following scan, exposed at EI 400!
The scan almost didn't need any postprocessing, only a very slight contrast adjustment was necessary. When I took the wet film out of the tank I immediately said "WOW". The rest of the film exposed at EI 100 was very dense, still scannable without probs but probably too dense for silver prints. So expose sparingly and/or reduce dev time. This film has blown me away. Attractivly priced, perfect quality. Drawbacks? I haven't seen any.
