    Re: Paper negatives

    Thanks, Ned. I'll give it a try at some point.

    I use Photographer's Formulary Liquidol at 1:3 dilution, 1:30, 72F and it tames the contrast quite well. You get a very warm toned paper negative that is relatively lower in contrast than straight paper developer.

    I hear Dektol is about the same when diluted 1:3...

    Thanks, Kino. Maybe I'll play with dilutions later. I just realized that Ilford makes a thinner paper than I used. That would make it easier to load into the holders. I'll also try using a 480mm lens instead of the 360. The big challenge will be getting people to sit for portraits.

    Re: Paper negatives

    When I took the 8x10 paper negative photos of Janice, I tried some with a yellow/green filter, and some with no filter. The yellow/green filter prints scanned just fine on a cheap Canon flatbed, but the prints with no filter were too contrasty for the scanner. Today, I finally got my 8x10 film scanner operational. I 'scanned' the paper negatives made with no filter on it using transmitted light. That worked just fine, but....if I showed those images to anyone, I doubt that you'd hear from me again. No filter lead to a massive increase in skin detail and tonal variation. Terrific, perhaps, for the old man of the sea, but not so good for a pretty lady. Yeah, I suspected that would be the case. Anyway, for that format and distance to subject, f/16 on the lens is better than f/11, imo. Basically, with f/11 and focusing on eyelashes, the subject's nose gets quite blurry. I don't mind a little of that, but too much is distracting for me. F/16 was significantly better, with the tip of Janice's nose showing just a hint of softness. Next time, I'm going to give Foma 200 film a try.

    Oh, this is a great tip! I'm going to try it this weekend.

    It takes a bit of testing. Make test strips and choose the longest pre-flash that is still paper white after developing.

    I use a variation: most paper these days has a mixture of 2 or 3 emulsions that have different spectral sensitivities. I like to pre-flash through a green filter... so that the green-sensitive part of the paper gets pre-exposure, but the blue-sensitive part still has some "lag time" before it starts to do anything. This is oversimplifying, but it's like giving the "low contrast" part of the emulsion a head start.

    But again, I like what you did already!

    Re: Paper negatives

    I used Tetenal Work paper, made in the 1990, Gr.2 but I guess now it is more Gr.0-1
    Slightly grey, not realy white but still usable.
    No filter in use, set of ISO 6.

    Lens were a 1870 made Derogy Portrait Petzval lens, 360mm f/4,5 @f/32
    Exposure time 9 sec.
    Scan at 1200 DPI as negativ, converted to positive by GIMP
