Hi Gray,
Few years ago, when I acquired my flash meter, I already found out that
there are different reflection rates for different films. It will certainly
affect the exposure accuracy. For example, the Fujichrome 100, kodak Gold
100 and Fuji Superia 100 (neg.), their different are up to 0.3 stop. You
have to understand your film's character very well if you want dead
accurate exposure.
