With enlargers, people do burning/dodging/masking, so I decided to see if I could make this work with a
#ContactPrint.
So, I want overexpose/darken the well-lit (so, in the negative, darker) outside bits, and underexpose/lighten the (in neg, lighter) tunnel interior. So I took an early crummy print and cut out the gateway.
I can put the surrounding part down on top of the glass that holds down the negative and photo paper, then expose a bit, remove it, and expose some more.
Kind of works.
Positioning the mask is tricky--definitely this would work better with enlargement prints (in that case, you can shine red light through your neg and use that to precisely align your mask).
But it seems to work in principle, at least.
I might honestly get better results just by making a dozen conventional prints with different exposure times and picking the one with the best balance.
But it's fun to try this stuff.
