Is Acros 100 the same in 135 and 120?

Hi,

As the subject line suggests, can I assume that Acros 100 is the same beast in both 35mm and 120? I ask as I developed both of these in pyrocat HD - the 120 has a nice noticeable brown stain and the 135, well, hard to tell if it stained. I imagine it is, but I was struck by the difference.

I have shot Acros a lot in the past and have not noticed a difference between 135 and 120. I have even developed them together in the same tank with the same results. But I don't use a staining developer.

At one time emulsions varied depending on the film size/format and where coated, but these days the science is more precise and there's no noticeable variations.

In the 60's/70's Tri-X varied depending on where it was made/coated, and Kodak data-sheets gave different times etc for EK Rochester, Kodak Canada and Kodak UK as well as the format.

yes, but

base thickness is different, that is all

.104mm 120
.122mm 35mm - 36x
