Nope, completely false. B&W 35mm films have a grey base which helps to reduce halation, which in roll film is accomplished by the paper backing. 35mm film bases are also thicker. But the emulsions are identical. TXP (ISO 320) though is different from Tri-X Pan (ISO 400). Both are available in 120 size.
Nope? Completely false?
You confirm exactly what I said:The films have a different base
, I said that.The emulsions are identical
Nowhere did I say they were different.
What exactly do you find in error?
My point was, and is, that there are differences in both the film used in 35mm still, and movie stock, and larger formats even when the same emulsion is coated due to both the film itself, base, which is not identical and the properties of the lenses and cameras used so a direct comparison is not accurate.
Do you disagree with that statement?
If so how is it in error or false?
And BTW not all
(edit - now that is LARGE format
) 35mm still films have a grey base, some are coated on a clear base and can be reversed processed for B/W transparencies and incorporate anti-halation as a coating layer.
I recently shot some of the cine-still
stock, (rem-jet removed BEFORE exposure) and the halation was significant, as expected.
