    Re: New darkroom sink options

    If you want a good sink for not much money, then build it yourself. You can fit it exactly to your needs/space and customize things for your quirks. Pine frame, marine plywood sink bottom, marine...

    Re: Terminology Question

    Much of the text concerns itself with the self-masking property of printing-out papers, i.e., kind of a built-in contrast control since the exposure in the densest areas of the paper is held back by...

    Re: Terminology Question

    "High-contrast" is more than likely what is meant here ("hard" paper being high-contrast and "soft" being low).

    However, since there are many German speakers on the forum here, the original German...

    Correct me if I'm wrong, but if you have a working septic system with a drain field, and it isn't contaminating your well water, then disposing of developer and some acetic acid stop into your septic...

    Re: Darkroom from zero: Chems disposal

    Most developers (pyrocat included, I'm fairly sure) and stop baths can be disposed of in a septic system. The developer components end up being inert and non-toxic. Stop bath is just acetic (or...
  6. Re: Does extending the center column accomplish the same thing as front rise?

    We're over-complicating this I think.

    When you use front rise to keep vertical lines parallel, you move the image. The image is much smaller on the film than in real life. If you think in scale,...

    Re: USING TILT and SWING TOGETHER

    Alan,

    If you read my previous post carefully and do a bit of extrapolating, you'll find your answer. :)

    Don't judge. Standardize on the recommended time for your developer and paper type (RC or fiber base). You can use a bit longer time as your standard, but going shorter than recommended times is not...

    Re: Development time for paper.

    Don't use film developer for prints. I doesn't work well and it just wastes money. Save it for film and buy some print developer.

  15. Re: Grandagon vs. Grandagon-N vs. Nikkor lenses. A light fall-off question.

  16. Re: Regarding depth-of field curvature with tilt

    Philip,

    A couple of things. First, depth of field works in proportion to distance from the lens (aperture, to be more specific). That's why there is more depth of field behind (farther) from the...

  26. Re: Foma Classic paper and higher contrasts: anyone else having issues?

    So, to draw conclusions from your testing: Fomatone Classic probably just doesn't have the contrast range that the Fomabrom products (or Ilford MG papers) do.

    Still, you've got a few grades of...

    Well, yes. You can also position the code notch at the top right of the holder, i.e., at the light-trap end, just as well. My problem with that orientation is that the film slides down in...

  31. Re: Volume \ flow rate for RC print wash

  32. Re: How to keep film ending up wrong side of dark slide after exposing

  33. Re: A question about farmers reducer staining

    If prints are underfixed when they hit the toner, you end up toning the residual silver halides along with the image, hence the staining. It is likely permanent.
