I got an enlarger

Discussion in 'Darkroom Developing and Printing' started by Justin F. Knotzke, Nov 24, 2003.

  1. Hi,

    A teammate of mine, lent me a Saunder LPL with Nikkor lens. Works very
    well (great price too). I'm making 5x7 or so prints and I have to set it to
    F16 to get times of 10-15 seconds.

    I am using Ilford Multigrade IV RC paper. Is this normal? A friend of mine
    says I should be getting 30 seconds or so for that type setting..

    Thanks

    I don't think 10~15s @f16 is wrong for 5x7 prints.
    Are they fully developped (at least 1.5 min in the dev)?

    Times changes a lot from enlarger to enlarger, depending on the light
    source intensity, and also with negative density.

  3. Its all relative to how dense the negative is. but typically I've heard
    that mid range on the lens apeture you should get between 16 &18 second
    exposures with a normal #2 filter and a properly exposed and developed negative.

    Those short times are an annoyance when multiple dodging is required. I do
    not know the setup of that particular enlarger, or what size filters it
    uses, but it may be possible to fit a square P size cokin neutral density
    filter in the filter drawer/slot.

    There is no standard time, because it depends on the enlarger, density of
    the negative, and the print size. The lens will perform a bit better at f/11
    if you don't mind the shorter exposure time. There is absolutely nothing
    wrong with a shorter exposure time unless you do dodging and burning.

  6. Ok, they were a little on the light side. I'm going to try F8 or so with a
    shorter time. I just wanted to make sure I was at least in the ballpark with
    those times.

    Now that someone has lent me an enlarger I have to say that making your
    own prints is a serious hoot. Better then digital IMHO.

    Thanks again to all who replied. This is a great group.

    Depends on the negatives but sounds fast.

  8. And there is nothing wrong with the short exposure when dodging or burning. Just
    use two or more exposures. A main exposure with the dodge and however many you
    need to burn different areas.

    Great if there is only one area to dodge, but agree, burns are easy. But
    then I repeat myself.

  10. Or stop down to f/45

    Does his lens stop down that far . . . at that aperture, if he has it, I
    would worry about distortion.

    At 5x7, using my DGA Dichro head with the condensers in the Beseler 23CII, I get exposure times of less than 10 seconds
    at f16. I thought the same thing as you but I guess its normal...

    I could get longer times if I switch out the condensers in favor of the diffuser. The Beseler gives me this option.

    It really depends on the intensity of your light source. Focused down to 5x7, the intensity is even higher.

  13. It ends at F16.

  14. Just some data points...
    I am using an old B7 Automega condensor enlarger to enlarge 6x6 negs to 8" x
    10" with an 80mm Rodagon... The optimum aperture for this lens is f:5.6 + a
    half click (f:7 ?)... My average enlarging time is 5 to 8 seconds depending
    on negative density...
    Using the Omega C760 enlarger with the dichroic head and a 105mm Rodagon,
    with the aperture also set to f:5.6 plus a half click, the same negatives
    average 12 to 18 seconds...
