I wonder if people are being taught to retouch negatives? If so, learning on 120 would be tough.

that's what i was thinking ...
but it seems kind of strange teaching
people to retouch small negatives with pencil
the enlargement factor is insane ...

even for someone with retouching experience
blending and spotting and retouching on a 4x5 or larger negative
and then enlarging ... is a big deal.
