Garimo,

I would have to go back and dig out the prints to be certain, but as I recall,
there was no significant, if any, difference in exposure. If fact, I'm sure
that the exposure was a control. i.e. I determined the proper exposure for
1 part A, 1 part B and then used the same exposure for 2 parts A, 1 part B.
And before you ask, yes, I did increase exposure for 1 part A, 1 part B to see
if it would increase the tonal range. It did not. Just got more black steps.
