  1. Re: Assessing film speed and development time without a darkroom.

    While in principle this could be done without a darkroom, it sure is rather inconvenient to contact print negatives without a darkroom.

    Yes, I've seen people make wet prints without a darkroom.

  2. Re: Assessing film speed and development time without a darkroom.

    Using a known-density reference (e.g. a stouffer wedge) you can use your scanner as a densitometer. Scan the reference along with the film in one go and 'measure' densities in Photoshop etc.

    Re: post alternative techniques

  4. Re: Printing color slides on Harmon Direct Positive paper

    No, but it does sound like a decent possibility. Two caveats come to mind:
    1: The contrast range of a typical slide may not match the paper perfectly - but thinking about it, it might match better...
  5. Re: Subbing silicon coated mylar for carbon tissue

    I've got x-ray here, probably even some blue stuff I wouldn't use for anything else, but I've only got 8x10 and that's too small for printing 8x10 negatives. Moreover I'd prefer something a little...

    While this is in general of course always good advice, there's as far as I know no reason why ventilation requirements would be any more strict for pyro developers than for other darkroom chemistry....

    Re: How to imitate the contrast of wet plate

    Try a blue filter. If that doesn't work, resort to UV photography. Most of the sensitivity of wet plate is in the UV band close to the visible spectrum.

  21. Re: How to finish, wash and dry fibre paper prints for exhibition and sale

    If outgassing from the glues in e.g. OSB are a worry (I don't think they need be, but YMMV), the suggestion of a barrier is a good one. I'd recommend something like BO-PET for this.
  22. Re: How to finish, wash and dry fibre paper prints for exhibition and sale
