Instructable for building a proper light-tight box?
I tried searching for "dark box," "light box," "film box," "film processing," even for pinhole cameras. I couldn't find an I'ble which directly teaches how to make a high-quality light-tight box (felt lined, gasketed locking lid, etc.). Did I just choose poor keywords? Do any of the photo-gurus here know whether such an I'ble exists?
For a couple of single-photon Physics I'bles I'm working on, I've realized that asking people to seal up a whole room and make it totally light-tight is ridiculous and impractical. I ought to get the same effect with a dark-box using a good viewport and head shroud. Rather than writing a whole I'ble myself, I'd rather cross-reference something which already exists.
