Tales from the Darkroom - Why was the print completely blank?

Discussion in 'Darkroom Developing and Printing' started by Francis A. Miniter, Jan 6, 2004.

  1. I usually like to think that I can do most tasks well when working in
    the dark. On more than one occasion, I have even whipped up a new batch
    of fixer or made a fresh dilution of developer under a safelight. But,
    sometimes one gets overconfident. Here is a story of one such incident.

    This last weekend, I made up a batch of stock glycin solution (Fn 1).
    From that batch I decided to make a 200 ml stock solution of
    Dassonville D-3, a print developer that I like. (Fn 2) At this point,
    there is no more than 5.3ml of glycin and 1.75 ml of hydroquinone in the
    stock D-3 solution. I prefer using the developer at a 1:15 ratio to get
    what Anchell (The Darkroom Cookbook, 2d Ed) calls the "photogravure
    effect". So I took 62.5 ml of the stock solution of Dassonville D-3 and
    added water to make a liter. Now we are down to 1.7 g of glycin and
    0.6 g of hydroquinone in the working solution.

    Then I turned out the lights, put a negative in the enlarger, decided to
    use a variable contrast filter #4 with the Ilford MGIV paper, and
    plucked the filter from the box in the dark. After determining the
    exposure time from the transmission analyzer, I exposed the paper,
    developed it in the fresh D-3 (1:15) and got absolutely nothing. I then
    exposed another sheet for 4x as long. Developed it until it was ready
    to come apart, and, nothing.

    It was late. I went to bed frustrated and confused. The next day, I
    checked my calculations and the pH of the working solution. Everything
    was fine. So, I set up with another negative and popped out the vcf
    filter, only to find that I had used the red safelight filter instead of
    a number 4 filter. I had all too confidently believed that I had put my
    hands on the correct filter and never bothered to read it under the
    safelight.

    Fn 1. 90 g of Sodium Sulfite (NaSO3), 140 g of Sodium Carbonate
    (NaCO3) and 50 g of Glycin in 1800 ml of water, stored in a glass
    container (old whisky bottle) and refrigerated.

    Fn 2. The formula is in Anchell, TDC. After determining quantities
    of each of the ingredients needed for 200 ml instead of 1 liter, I used
    187 ml of the stock glycin solution, and added to that the quantities
    calculated above for a 200 ml solution, less those supplied by the
    glycin solution. These additions brought the solution to 200 ml without
    the addition of further water.

    Sounds like me trying to figure out if it's a green or a blue filter. Of
    course I enjoyed dropping a full box of paper even less-)

    Well at least now you can have full confidence in that red filter. ;-)

  4. Loading a roll of spring steel that Kodak calls 400TX, I lost my grip
    and the film fell on the darkroom floor, I knew not where. I got on my
    hands and knees and felt the whole floor to no avail. I finally muttered
    a pious ejaculation (as my father taught me) and turned on the light.
    There it was, tightly coiled. I said what the hell and developed it
    anyway, figuring some of it might show something. Every part of it was
    pretty well fogged, but I actually got a few good pictures by scanning.
