I understand almost nothing

Testing... 2













Well, comparing 1962 Perutz Peromnia and 1963 Ilford Selochrome was easy. Both had fog, but what a difference, and Peromnia lost almost all sensitivity while Selochrome was still 21/100.
PS Selochrome wins - but do not forget: I don't know how the films were stored all that time! As I said earlier: no science, just fun.
