You realize Tom that each postcard is (in most cases) an individually printed darkroom print?
The postcard exchange is an APUG exchange, intended to allow us to share our photography with other APUG members. My 24 cards will each be exposed individually in my enlarger, developed in (mostly Kodak) chemistry, washed, toned, dried, labeled and mailed by myself.
Most others do something similar.
Can't blame a guy for defending his livelihood, even if it is making wagon wheels and buggy whips now, can you?
