It works, for sure, no surprise. Developed two films, one 135 Pan F+ EI 50, and one 120 Plus-x EI 100. I did cut the Pan F in two and did the other half of it in Rodinal 1+50. (I was lucky and cut it right after 18 frames, just a 2mm cut into frame 19
Times were based on Massive dev chart, the same as Kodak and Ilfords times on their web sites. 4 minutes for Pan F in HC-110 B and 11 minutes in Rodinal 1+50. Plus-x 3,5 minutes in HC-110 B. Because my darkroom was 25 degrees C, choose to develop in 24 C (75F). I used dilution H for Hc-110, 1:63. I did both half the Pan F and Plus-x in a tank, and decided for 8 minutes (doble time of B + 1 min for the Plus-x). In 24C this was converted to 5 min 30 sec. The Rodinal 1+50 7 min 30 sec. I used a syringe to extract 15 ml of HC-110 syrup and added 930 ml of water from the tap. Rodinal 10 ml + 500 ml water.
Agitation, first 30 sec, then two inversions at 1:30, two at 2:30, two at 4:30, and for the Rodinal, two at 7:20. Rinse with water - 25C, Fix with Kodak Max Fix 5 min, rinse with water again, and Hypo C.A. 1 minute. Rinse for 5 minutes in 24-25 C, then Agfa Agepon wetting agent. Dried the films in room temp.
The Pan F looks good. A little more developed in Rodinal, and more contrast. The Plus-X is underdeveloped, very thin, and low contrast.
I have the negs here and will scan them, but of course, they must be printed to see how they are for sure.
