Last Summer, I set up a B&W printing/processing area in a corner of a room in my home. I found a convenient way to block the windows so that I can print even before the sun goes down. It has been working just great.
Then today with the weather turning cold, I was out back splitting wood and it suddenly occurred to me, "During the sub-zero (C) weeks of winter, when I have a warm fire burning in my woodstove with it's glass window front and plenty of long evenings to catch up on printing negs. How the heck am I going to keep it dark enough to print?"
Anybody got a very high temp red safelight filter?
