Here is a series shot on 160 VC and processed with normal development times.
They are scans of contact prints on Endura paper with constant exposure time (12") and only the f stop was varied.
The exposures in order are leftmost normal ISO 160.
Second column ISO 25, 50 (top, bottom)
Third column ISO 100, 200 (top, bottom)
Forth column ISO 400, 800 (top, bottom)
You can see visually the huge latitude. I did the same test on Portra 400.
Shot with an RZ67, prism meter on auto.
