    How Dark does a darkroom have to be?

    I have a little bit of light coming in from the bottom of the door but the sides and top look pretty good except for a small crack at the top left corner.

    Thanks,

    Kev

    I have light all round the door, and some light coming through my improvised window blackout cover. I develop sheet film by inspection without a safelight - my eyes are dark-adapted halfway through the development, which is just when it's getting useful to see the negative.

    Yet I have never had any problem with fogging - not even with HP5. Does that answer your question?

    this is how my bathroom/darkroom is. i try to keep my body between the paper and the door, just to block out any extra light like that. i remember that paper is rated asa 3 or 6, something pretty slow, so i dont let a little extra light bother me.

    remember that light does not bend, but it does reflect, so as long as you don't drop the film right in front of the door you should be alright.

    Throw a towel on the floor to cover the crack.

    I couldn't think of anything witty to say so I left this blank.

    Kev,
    Be safe and not sorry. Put a black curtain across your door and a sausage thingy along the base of the door. I had the same problem and the above solutions stoped all chinks of light coming in around the door. OK, you may get away with it - but why take the risk?

    Cheers,
    Neil.

    If after 10 minutes in your darkroom you can see things with out your safelight on, then it's not dark enough. Now of course maybe you "see things" in broad daylight, so I can't help there. No, shut up, I'm talking here, get off my keyboard .......

    I'm almost finished lightproofing my door. I put extra wide door stops all the way around and stapled black fleece around it, seals up great..

    Depends on what you're doing...

    Developing film in trays? You really want it pretty close to totally dark.

    Printing B&W with an enlarger? You want it pretty dark, but some light around the door is probably no sweat. I've been in several group darkrooms that don't even have doors, just black, S-shaped entryways.

    Contact printing Azo? You're probably okay as long as you don't actually turn the lights on. :-)
