    Anyone out there coating glass wanting to produce positives?

    We would be willing to do some extensive testing and free processing for some good samples.

    Call me at the lab or email;

    Same here.
    This also reminds me I should look through the book I have about developing lantern slides.

    Yes, indeedy. I've gotten a fair start. With one holiday thing and another, I'll probably not be back at it until after the first of the year, but I'll be sure to get in contact with you then.

    Here's a bit of where I'm at: A section already posted on my website and a 2-1/2 x 3-1/2 Baby Speed Graphic positive (handmade emulsion coated on Melenex subbed film base.) The image is a straight, unmanipulated scan (i.e. it's not inverted.)

    Interesting. My Beseler Slide King will handle lantern format, and I have a few historic lantern slides. They're really contrasty, as they need to be for projection. I thought I might try to dupe or scan a couple of them and make prints, and they're very hard to print well, but they look great on the projection screen.

    I've been looking into doing this, and I was wondering if anyone here knew of any adjustments that would be made to the coated emulsions, i.e. something to increase contrast/dmax or tone the final positive? It would seem that a thicker, higher silver content emlusion would be better.

    Can one use black glass instead of transparent glass, coated as normal, to create a positive looking image?

    Not if you want to project it.

    ...to be more clear, I would need someone coating glass, exposing, then send those plates into us for dr5 processing...

    regards

    IIRC Ilford still have the capability of coating glass plates for Nuclear chemistry. IDK if this has to be a special order or wether they release product into the chemical / nuclear supply chain and remake as appropriate.

    Not a clue, however, I'm sure mr Galley would fill us in with the details if needed.

    Looking at your website, you certainly have got some good results with HP5/FP4/Pan F
