8x10 Camera -> enlarger conversion/add-on?

Discussion in 'Darkroom Developing and Printing' started by Collin Brendemuehl, Oct 27, 2003.

  1. Is there such an animal?
    Contact prints alone will be great, but are there options in this arena?

    TIA,

    Collin

  2. Not as common now as at the turn of the last century.

    Ansel Adams made himself one. Pictures and description are
    in 'The Print".'

    I know of no commercial unit. Beseler does make an
    8x10 adapter for it's 4x5 enlarger.

    zone vi sold a conversion head for the zone vi enlarger which was a 5x7
    unit. I think you might get one for that if you look at
    www.calumetphoto.com and search for zone vi.

  4. DeVere 5118 is 8 x 10
    DeVere Vulcan is 10 x 10
    DeVere 508H is 8 X 10
    DeVere Metro is 10 x 10
    Omega Chromega F is 10 x 10
    I suppose all of these still are in production.

  5. Yes, there is such a thing as an 8x10 enlarger. New, they are quite
    expesive and large. Beseler makes a head for their 4x5 enlargers that
    will do 8x10. I have heard that is is not really very satisfactory as
    8x10 heads go.

    Aristo makes a variety of cold light heads which will cover 8x10. I
    believe they have up to a 12x12 cold light source.

    If one is handy with the tools, I have seen a cold light source mated
    to the business end of a 8x10 view camera and used as an enlarger.
    Another poster mentioned smething Ansel Adams made in the 40's which is
    very similar to this approach.

    Also, since many print shops are phasing out silver based printing
    sources, a horizontal camera could probably be aquired and adapted as
    an enlarger for a reasonable cost.

  6. I think even the used ones are large.

    But in any case, they are available used. One maker of these beasts was made
    by Elwood (Elwood Pattern Co.). I recently got one of their 5x7 enlargers--for
    $9 (from eBay). They may not be Omegas, Beselers or Dursts, but they do work.

  7. That's what I'm looking for, either a unit or a design.

    Take a look at Doug Bardell's page http://www.cyberbeach.net/~dbardell/ he
    builds his own stuff, including a 12x12 enlarger. If you see his FAQ you'll
    see he make his plans available for the price of the photocopies and mail
    stamp, ask him if he has the plans for his enlarger.

  9. I don't know of any currently made adaptors but its not
    too difficult to make one.
    You must make an adaptor back to take a negative holder.
    This can be as simple as a board with a slot to take a glass
    sandwich.
    I've thought about lamp houses considerably. My current
    idea is to use a metal box with the sort of fluorescent
    lamps used to replace incandescent reading lamps.
    The lamphouse is mounted on a simple frame which also
    takes the camera. This way the camera does not have to
    support any weight but its own.
    The camera must be one with front focusing.
    The frame with camera and lamphouse can be mounted
    horizontally or vertically if you have a sufficently heavy
    duty tripod. Horizontal is easier.
    If you use my idea of fluorescent lamps they should be
    allowed to run continuously and a shutter of some sort used
    to regulate time of exposure. Fluorescent lamps change
    output with temperature; they like to run hot, and are not
    suitable for intermittant use.
    This sort of rig requires no changes to the camera which
    can still be used as a camera, plus the whole thing takes
    little space when disassembled.
    "Real" 8x10 enlargers are available used for not much but
    are _very_ large. You really can not appreciate the size of
    an 8x10 Omega, Saltzman, deVere, Elwood, until you are in
    the same room with one. You will think the Martians have
    landed. If you have the room one of these guys will work
    very well. Otherwise the adaptor will allow enlarging and
    also making enlarged proof sheets without needing a ball
    room sized darkroom.

  10. 10x10 enlargers are often free for the taking. Look around.
