I use mostly slide fim and use the general 4 stop-spread rule:
+2 stops = white
-2 stops = black
Very handy with the spot metering of the OM-2S/ OM-2sp.
The OM-4 highlight /shaddow-function uses some what more spread.
Most slide film are in the 4..5 stops spread area, but do capture
a bit more. I don`t like to go to the extreme.
I´ve noticed that pushing a film reduces the stop spread.
But I think pushing a film isn`t a good deal with my
mass-marked-processor at all ( bad color shift..., well it was only a try)
But the stop-spread differs from film to film. Print film usually
captures a much wider range, but the copy proceccs usualy
only use a 4..6 stop range for the prints.
