    Glass Neg Carrier Woes

    I have the glass neg carrier for my LPL C6700 - it's a massive, massive pain to get and keep that thing clean, i.e. free from dust etc. Is this a common problem? Am I really gaining any benefit with this carrier other than it's universal? Any ideas appreciated, including for cleaning products.

    I use Zeiss wet cloths to clean the glass and then use a can of air to blow off any loose stuff as well as the negative.

    The carrier will keep your neg perfectly flat, and that is a big benefit

    I take from your location, Salisbury, UK (great place by the way) that your enlarger is not sitting in the basement, correct? If so, have you ever measured the humidity level of the room the enlarger is in. It still being relatively cold, your air might be too dry, and you have more than normal static and, consequently, dust. See if this problem gets less during the summer months. If yes, a humidifier may help. Some darkroom workers spread out a wet towel a few hours or so before they print to get the humidity up, but I have not tried that. I don't print without glass carrier anymore. I find it almost impossible to get a really sharp print without them. I rather dust than compromise on sharpness.

    Where can you get these wet cloths?

    Are you using it with collimated light? If so, then efforts at removing all the dust may be futile. With diffuse light, small dust particles on the outer surfaces may not be seen or they will be less obtrusive. Sometimes you can get away without the glass carrier. I'd estimate I use a glass carrier 40% of the time.

    Minox: Glass always
    16mm: Glass always
    35mm: 50% glass-50%glassless
    120: Almost always glassless
    4x5: Almost always glassless
    8x10: Glass always

    Hi, I use the glass carrier always and find it easy to keep clean using an air blower and occasionally a brush or micro fiber cloth. I think it is great for keeping the negative flat and to be able to print full frame.

    Always glassless!

    From 35mm to 8X10.


    I stretch the larger negs using black tape in the corners. They stay flat that way!

    Thanks for all the input.

    We're in a brand new house and the darkroom is in the downstairs bathroom, used solely as a darkroom and nothing else. I think I've figured the problem now, When I installed some shelves I was too excited to clean up.. maybe there's a lot of wood dust particles about. Anyway, I'm sorting it now so hopefully that will be that.

    Thanks for the ideas, I'm definitely going to persevere with the glass considering the consensus on improved sharpness.

    Cheers guys!

    I would second the Zeiss wipes. I've seen them in action (with lenses) and they're excellent. You can get them at B&H.

    Per

    I like your approach, but the total depth of focus for a 35mm, 10x enlargement at f/5.6 is about 0.5 mm. A 2x enlargement of an 8x10 negative is about 0.7 mm at the same aperture. A little heat from the light source and the negative will 'pop' out of focus. A glass carrier is the only way to hold a negative flat.
