The equivalent of an 8X10 sheet is a 36 exposure roll of 35mm. Think of it this way, a 36 exposure roll fits on 1 8X10 sheet of paper, so what ever amount of film will fit on an 8X10 sheet is the equivalent of the same.(posted 9320 days ago)As concerns capacities and replenishment, I have never replenished HC- 110, I always use it one shot. At dil. B it is very economical, and the consistancy of one shot development is what I am interested in. I am concerned about the inconsistancies of calculations and replenishment, and personally don't want to risk my film for the possible savings.
