Jose, I looked up some development times for APX100 35mm film. I develop in a Jobo CPE2 at the slow speed.
I started using APX100 in mid 1993. I have used about 200 rolls since, bulk loaded.
I used D76 undiluted (neat) at 20ºC for 7'30" which was really good for me at the time. I haven't changed much as I still use the same camera and lens.
I have also developed APX100 in divided D76 at 20ºC. First development for 3' and second development for 4'45".
When Xtol came out I tried APX100 in that, I came up with the time of 5'30" at 21ºC. Undiluted (neat) developer. My notes mentioned that the negatives were really good. With a film speed of about 100ASA
However, I use D76 all of the time.
Hope this gives you some working times to start with.
Mick.
