Klopt, zag ik ook al staan in The Darkroom Cookbook, 3rd ed. p.223:
"FORMULA #36
POTA
(Marilyn Levy)
This formula was originally designed by Marilyn Levy to record nuclear blasts on conventional films. It is capable of recording light over a 20-stop range. With modern films, the results are low in contrast. However, with films such as Kodak Technical Pan (discontinued), it produces a full gray tonal scale."
Dat is dus meer dan 20 stops bereik.
