i am having trouble exposing a 12" x 12" pos phot board. i have done
this before on smaller boards successfully. i am using two MG
chemicles 15 watt light fictures at each end of the board. the center
of the boards develop ok but the corners aren't getting enough uv.
i was wondering if anyone has successfully exposed a 12" X 12"
board ? if so how. thanks
