When exposing a photo-resist, one tries to avoid ambient light as much
as possible.
My solution with mask-exposure is a dark room and a cable with a switch,
that I can toggle from outside.
Had I an CNC machine, I'd be clever enough, to implement a delay to just
walk out
of the room ;-)

My method of choice is toner transfer.
