Adox CMS20 II film has loads of detail, but is fragile and has many pinholes in the emulsion (from what?). It needs to be shot at ASA 5-6, not 20, and developed with their chemicals for 15-20% less time than specified on the box. As you can see, I didn't think to use a yellow/orange filter, which would have shown the brooding clouds to much better effect. My inexperience at work.
