Last weekend I tried my first roll of Rollei RPX 25, a slow, fine grained film. I shot the roll on my Rolleiflex 3.5E3 and I developed the film using Rodinal 1+50 for 14 minutes @ 20 C. High contrast is often a challenge with these slow films, and although the negatives looked contrasty to the eye, I was able to coax good highlight and shadow detail out of them. I will be using this film again!!
