    Should a color darkroom always be without lights?

    Should a color darkroom always be without lights?
    I have the feeling I once read an article in which was stated that it is possible to have special spectrum lamps that also allow you to see stuff even in a color darkroom. Something about Natrium light??

    Anyone a clue, I could not find a thing when searching the forum
    Thanks GAme

    Since color film is sensitive to all visible light the color darkroom must be completely dark.

    Sodium vapor safelights can only be used with B&W papers.

    In previous port said "film" and meant to say "film and paper".

    I've been told by experienced workers that RA-4 papers to in fact permit a very dim orange safelight. I don't know if it can be bright enough to actually see anything, but at the least, it'll let you cut down on bumping the enlarger with your head...
    Photography has always fascinated me -- as a child, simply for the magic of capturing an image onto glossy paper with a little box, but as an adult because of the unique juxtaposition of science and art -- the physics of optics, the mechanics of the camera, the chemistry of film and developer, alongside the art in seeing, composing, exposing, processing and printing.

    Ok, well I can always ask my photoshop (the actual store outside )
    but I don't know if they'd know anything about it.

    The orange light I never heard of, but I very dimmed light would be pleasent I feel. In a B/W darkroom I can see quite good after an hour.

    Anyone else?
    Thanks

    I always work in the dark until my paper is entirely in the processor. However; Both Thomas for their sodium vapor and Jobo sell safelights that emit light of a very narrow wavelenght band that are supposed to be usable with color paper.

    How good do they work? dunno.

    Thanks Claire.
    I already thought something like this existed.
    Maybe there is someone that has actual experience with these kinds of light.

    -can one see something with such a lamp or is it too little light?
    -doesn't it affect the prints at all?

    I have a very nice darkroom lamp - Durst Sanat, dedicated primarily to colour work, with a natrium spectral lamp inside plus an interference filter... alas, it was designed for old papers Today's papers like Kodak Endura are so sensitive that they get the nasty bluish fog with the lamp, though its light is quite indirect. One can minimize it by using some ND filters inside the lamp, but I prefer to work in a complete darkness for better safety. The ergonomics of your color darkroom is quite important, then

    The most used sodium safelight over here is safe providing that it is not too brightly set. (it is adjustable) It is always wise however, to carry out light checks as distance from sensitive materials is often critical.
