    FOR SALE

    2 11X14 cameras

    DIMENSIONS
    13.25 x 16.25 x 24 "

    OPTICS
    11" ( 286mm ) f 8 lens ( plano convex )
    13" ( 333 mm ) f 16 lens ( plano convex )


    DESCRIPTION

    these cameras are simple construction of my own design.
    they have a focus screens.
    waterhouse stops are not included, but can be easily made.

    this camera is NOT fixed focused, and while a lens and lensboard are included, ANY lens can be used.

    why am i making these box cameras ?

    to make a long story short, i love box cameras and i love experimenting.

    i am selling these in the "anything goes" area
    because the paper negatives made with these cameras
    are " in flux " i am currently trying to figure out a way to FIX them,
    so, for the time being, the images made are ephemera.
    after the exposure is made and an image forms on the paper,
    the paper negative is scanned
    and becomes part of a hybrid-process.
    the negatives created are chemical free ...
    feel free to look at images in my apug gallery
    to see what can be made with this sort of camera.

    65$ each (shipping not included).
    paypal only ..
    I never ask for "gift" option, please split paypal fees.


    custom camera sizes are made upon request.

    Question on loading, John: Are there rails or guides or somesuch to hold the paper/film in place? Also, anything to cover the back focus screen once loaded?

    hi david

    nope there are no rails or guides.
    the focus screen slides in and out and is held in by friction
    to the inside of the box.
    once the focus is determined i use masking tape
    to mark off and hinge the back
    and tape the film right to the edge of the focus screen.
    there is a uncut piece of foamcore that i put on the back
    after the paper is inserted to keep stray light out .
    you can also put picture frame corners on that uncut board, and put your
    paper on there ... or make a window mat.

    I think the paper negatives are fascinating for art purposes. I'm wondering if you can use film in an 11x14 film holder? I've done some paper negatives and have scanned, then reversed the image, and made prints. Of course you could print them in a contact frame to get a positive print.

    hi there

    i imagine you could use film in a holder,
    but it wouldn't be the best route.
    the focus screen slides inside the box,
    so it would be hard, unless you pierced a hole into
    the box and slid the film holder down from the top
    i have a design like that , but it was a real PITA ..
    the other problem is ... there is no shutter ( yet ! )
    so the exposure times would be kind of too long ..

    i too love paper negatives, almost more than film :smile:

    If the paper negatives can be removed and stowed in a changing tent, they should be able to be processed like any piece of paper, I think.

    If there was a pinhole version of one of these that would fit into a changing tent, I am sure that the experimental photography teacher at my school would love to have one available for students in the class. Maybe 8x10, and we can make the pinhole ourselves? It also would not need to focus, or have a ground glass. Or maybe she would prefer the lens, focusing screen, and focusing ability. I will ask her and get back to ya. The huge changing tent would surely cost more than the camera!

    Just for my information, is one sheet of black foamcore able to stop light, or do you use multiple layers or additional coatings on the foamcore? What tape to you use?

    hey 2f

    its magical foam core and magical black masking tape that have no problem with light leaks


    i suppose a pinhole and changing bag could be used,
    but that's no fun :smile:

    since the paper is long exposed, not short exposed
    it will turn black-as-night in developer.
    these cameras are intended for long (lumen print type)
    exposures 1 to 4+ hours so the image projected onto the paper
    kind of burns onto the paper.
