    Hi Folks
    I'd like to make a 35mm View Camera:

    1. take a 35mm SLR
    2. leave the back open so I can always see the lens
    3. lock the shutter OPEN

    4. put a view screen behind the lens where the film would usually be
    exposed
    5. invert the image so it's no longer upside down
    6. make the brightest, most evenly illuminated image

    I know how to do steps 1-3.
    I'm more clueless about steps 4-6, especially what material to use for
    the screen. I've tried a ground glass but It's neither bright nor
    even. I also tried the focusing screen from a dead 35mm SLR. Better
    but still not great.

  2. 4. Use glue

    5. Can't due that one without using some mirrors or other optical tricks,
    which are not likely to fit in the camera.

    6. It's not going to be bright. That is why view cameras have hoods. The
    best bet for material is the special glass made for use for view cameras.
    You idea of using the viewing screen from the viewfinder was good.

    Maybe if you told us what this was all about, we might be able to make
    some better suggestions.

    Ordinary 35mm SLRs already do 5, 4 and 6.

  4. I suspect we have a troll. The questions, as you noted don't make any
    sense in the normal world. Trolls don't live in a normal world, they can't
    cope with reality.

    The picture is inverted on a view camera - that is the purpose of the
    pentaprism. You could always stand on the ceiling.
    I can't really figure out what you hope to gain with this approach since
    the SLR already has all teh features you want just by looking through the
    viewfinder.

  6. Yes....I suspected troll....But I don't have enough information yet to issue
    a, "troll alert". There is no advantage to building such a thing...The whole
    advantage of a view camera is the larger cut-film size.....And all view
    cameras invert the image....To try to put the image upright would be near
    impossible......

    No, you don't have a troll. And the questions can make sense in the
    "normal" world. Why has usenet gotten so abusive? It's really quite
    sad.

    Anyway, I'm attempting to make a poor-man's version of the Mini35 -
    see www.mini35.com. This is a $7000 gadget that gives a DV camera the
    depth-of-field one gets with a 35mm camera.

    Quite clever really. And it even makes sense in the normal world.

  8. The web page was too obnoxious to spend time with, but if
    this is what I think it is, you also need a way to prevent the imaging
    of the ground-glass texture in the video picture. I think this is done
    by eccentrically spinning the focus surface - not an easy thing to
    do while keeping good alignments for accurate focus. $7000
    could buy you a good used video camera with a much larger CCD,
    giving some of the same limited DOF effect with better results...

    Not at all. You can buy focusing hoods for view cameras that put the image
    right side up.
    They have been available for years.

  11. Interesting....I never saw one, and my father used view cameras all the
    time...they must be bulky things....Especially for the larger
    formats.........My dad just looked at the upside-down image on the glound
    glass under a black cloth.....Of course, this was back in the late 40's.....

    Large format SLRs and TLRs have been made. Some are still being used.

    If you want bulky

    http://www.petergowland.com/camera/

    Scroll down to the 8x10 TLR.
