    Re: Selenium Toner for Archivability

    Get a bleach and test it. I can’t bleach a print that’s been toned 4 minutes at 1:20, so something happens in that time. What you have with partial toning is two images, one part is metallic silver...

    Re: Need Guidance on Getting a Sensitometer

    Wow fun thread. Use a sensitometer to find things out about fresh film: your development time. The test you do that results in an ASA parameter match, with fresh film in a standard developer,...

    Here’s what I did...

    A Polaroid conversion weighs 3 pounds. I went with Littman.
    A Grafmatic weighs 1. Buy 3 but bring only 2 of them plus a few extra septums because you will bend some.

  15. Re: Seeking Large Format B&W Negative Repair Tips

    I use regular Kodak red opaque on the base... it washes off easily if you think it's worse, or if you want to try again.

    It is far easier to spot a print from white than to retouch a black mark. So I use opaque on the negative and leave what would be atrocious white marks on...

    Re: Starting 4x5 - Which film?

    Because you have more square inches of film than medium format, you can use a slightly faster film.

    TF-4 is an alkaline fixer, so the advice may be to leave the lights off for a while.
