Hello everyone!
Does anyone know the standard development time for Adox CHS 100 in Xtol 1:1?
Thanks in advance!

I’ve since managed to answer that question myself.
Here’s the answer, in case anyone’s interested:
The film has a sensitivity of 50 ASA; at 20°C and with a 30-second agitation cycle, a full 10 minutes is a good exposure time. The film can be developed in the same bath together with CHM 125, which should then be exposed at 64 to 80 ASA.

Something must have gone wrong.
XTOL’s speed performance isn’t actually that bad.
I’ve never tried a 1+1 dilution, though.
Do all films lose speed that much at that dilution?
I thought that with XTOL, that wouldn’t happen at higher dilutions.
Our true rating for the stock solution back then (1998) was 80 ASA for the CHS and 100–110 ASA for the FP4/CHM

The film gets off to a very slow start in Zones I and II. The LogD in Zone II is 0.09 (during exposure at 100 ISO), as measured using a Heiland split-grade chart. The curve is shifted by one stop overall (1.25 in Zone IX), so it is correctly exposed at 50 ISO. That should be correct. And I also find it acceptable; full shadow detail isn’t always necessary.

Something positive for a change:
The first results have turned out really well – the CHS 100 is brilliant for portraits!
