Yep, using lightdims here, too- I have a sheet of silver and sheet of black. They're pricey but oddly nice, and a pack lasts for ages. They help a lot in dialling the baleful Cyclopean glare of your average Schitt unit down to something more socially acceptable. I like the odd errant glow, that looks nice in the sort of perpetual gloaming in which I prefer to live. A few stray photons is fine, I will develop my film in the internal bathroom. I just don't want to get a tan from the power LEDs.
