    Obviously, it's each to their own, but my question is this, if it isn't COMPLETELY dark, how do you know when it's not dark enough? I would rather be safe than sorry.
    I'm into painting with light - NOT painting by numbers!

    I loaded film in the completely dark darkroom of a daily newspaper for 15.5 years. The film looked no better than the film I loaded in the near-dark darkrooms I had before or that I've had since.

    I've always tried to make my home darkrooms as light-tight as possible but it's impossible to do so when the room is also used for other purposes and other people are involved. My current darkroom is in a tiny bathroom and it leaks light around the door. I really can't tape the door closed and as long as the light isn't enough to fog the film, I can live with it.

    The Eye's ISO - Box Speed

    Checked it out, via Google of course: ISO after 1 minute of
    complete darkness 28,000; after 5 minutes, 132,000; after
    60 minutes nearly 1,000,000.

    Curious though. Any body have an idea? Dan

    What shutter speed would that correspond to. I wonder? And what's the aperture of a fully dilated human pupil?

    Anyways, in late-evening light my darkroom is dark enough that it takes 5 minutes before I can see the film that's in the developer tray, by which time the film is more than half developed. So as my night vision improves, so does the clarity of the image - and when it looks right, I drop it in the fix. Nice negs every single time, and not a hint of fog.

    My home network router and cable modem are in one corner of my darkroom. I didn't want to cover the LEDs with tape so I simply painted the area behind them flat black and then turned them toward the wall. This worked beautifully.

    On a side note, cover your enlarger lens with a lens cap, sit in total darkness for a few minutes and then turn your enlarger lamp on. I was absolutely stunned by the amount of white light emmitted by the enlarger.
