    swirly rb67

    Hello everyone,

    I would love to get swirly petzval-like effects with portraits on my rb67. Is there any way to do this? I don't know much about petzvals but I assume that the swirling occurs at the extremes of the lens coverage on a 4x5, so would shooting it on 6x7 would mean that the swirly bits won't be captured on the negative?

    Old petzvals have been adapted to SLRs before, but I believe this involves a goodly amount of custom machining. If that's not for you and you're okay with shooting 35mm instead, Lomography has started producing petzval lenses for Nikon and Canon.

    thanks eyesage - I probably would have been interested in that if the funding campaign was still on and I could have had one for the $300 or $350 price. I assume they will cost significantly more than that once they are released.

    I can't justify getting into custom machining a lens mount so I guess I am out of luck for the RB, eh? I was hoping someone had done it already.

    On an RB67, what would you do for a shutter?

    well that would be one of my questions. Perhaps someone has figured out how to attach a petzval to the parts from an RB lens (the mount and leaf shutter mechanism), or perhaps a way to attach a LF lens board to an RB? This kind of thing? http://www.apug.org/forums/forum379/...-shutters.html

    Anyway I guess it would probably be a crazy amount of work.

    I have seen 4x5 monorails go for as low as $50.00 without a lens. Used 4x5 film holders sell for around $5.00 a piece. It's nice to have five so you can load a box of film. If you don't have a darkroom you can use a changing bag to load them. An old black T-shirt or sweat shirt works great for a dark cloth. You will want a cheap 4x loupe. You probably own a light meter.

    If you don't like sheet film you can use a 6x7 roll film back on the monorail.

    Add your Petzval lens and away you go!

    can you put a petzval on a crown graphic? I know almost nothing about LF cameras, but I do have access to a crown graphic, with 4x5 and 6x7 roll film holders.

    I have heard of people using Petzvals on Speed Graphics. The advantage of the Speed over the Crown is that the Speed Graphics have a focal plane shutter.

    what do people normally do for a shutter when mounting a petzval on a view camera?
