    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,...

    I would calibrate the SEI to a trusted meter when you have it. For example set both SEI and your Pentax meter to agree... then put some Scotch tape on the SEI ammeter glass and draw a new...

    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.

    Re: Sensitometer For B&W Film?

    Great video Greg!

    Daniel, an enlarger will work fine and Greg's right. You want about a half second exposure. (Avoids reciprocity failure issues). How much light? Don't overthink. Just do trial...
  14. 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.

    Re: Quick Question Tray Processing

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

    I don't know first hand, but think you might be better keeping the lights out.
