I just found this interesting -
I use D76 for many films - at 1:1 - as a one shot use
I shot some 4x5 T-Max for the first time yesterday - as well as some Ilford FP4 + -
I developed the Ilford with it at 1:1 as before - turned out fine
then I looked at the data sheet for D-76 to confirm the time FOR T-Max- and was surprised to see that although the roll film chart gives a time for 1:1
the sheet film chart only gives a time for full strength -
not a problem - i can do it and keep track of the number of sheets I've used it for
but I am curious if any of the folks with more scientific minds than mine can say why its only full strength for sheet film
thanks
