Thought I´d post this, mostly as a sticky note to myself. 
Adox CHS films:
Speeds ISO 25/50/100 - 15/18/21 DIN
Reciprocity failure
1/2 Sek. no change necessary
1 Sek. plus 1/6 stop (1,2x)
10 Sek. plus 1/3rd of a stop or exposure times (1.3x)
100 Sek plus 2/3rds of a stop or exposure times (1.5x)
I ordered 2 boxes of the 4X5 iso 50, still waiting for it to arrive.. I going to the "Four Corners" area in mid october and I chose to try these films on that trip.
