Lamp colour

  1. Hi.
    I am thinking of setting up a darkroom and was wondering if a colour
    safe lamp is the same as a black and white one?
    I have seen some on Ebay going quite cheap,
    I have ordered a book on darkrooms but it has not arrived yet,

  2. No, you can't see a thing with a colour safelight except a dim brownish
    glow, and black and white ones light the room with orange or
    yellow-green (special spectrum, depends on the paper type you use) well
    enough to see everything. Get the right type.

  3. My experience agrees with what David says. The amount of light from a
    "colour safe" safelight is so low as to be useless. B&W lights
    definitely fog Ilfochrome, and I imagine other colour material.

    My practice is to work in the dark, but to help do this I place small
    squares of luminescent tape on light switches, enlarger controls and on
    strategic points in the darkroom (especially on sharp bench corners!).
    These do not cause any fogging, but allow me to find my way around in
    the dark. Since all colour paper processing is done in daylight drums
    (Jobo) this works fine.

    I do not wish to confuse the issue, but in black&white darkrooms I have used
    a red safelight was used. However, for the only colour darkroom I have been
    in and this was for printing Cibachrome images, a green light was utilised.

  6. I always used a deep orangey brown filter for Cibachrome and understood
    it to have been the correct one. It was just about bright enough to tell
    whether the paper was upside down or not once your eyes had accustomised.

  7. It is safer (and probably easier) to do this by feel. The image side is
    shiny/slightly tacky, the reverse makes a slightly scratchy sound if you
    rub your fingernail on it.
