Smena Siam

2012-11-28 37

One body, two lenses never looking at the same direction. A camera designed by me to have more fun with mixed doubles.

The idea of designing such a camera was inspired by my irresistible desire to make controlled doubles in real time as we do multi-exposures shots. And saying doubles I mean shots mixing usual exposure with a redscale one.

Moreover, I tried a lot of times before with usual cameras to match two exposures of a future double shot using masks placed directly in front of the film. But I didn’t manage to match to images precisely because of inaccuracy of the camera rewind system. Images shifted leaving black “shadows” or even holes of used masks. Sometimes it looked good, but usually not.

So I took a Smena 8M as a base to create a camera having two lenses from both sides of the film. As the result, I got a camera letting me make usual and redscale shots after each other or mix them having at least a general idea what I’ll get.

Also I can match masks more precise now.

And finally Smena-Siam itself.

I believe that such a “siam” camera could be build on the basis of other film cameras. The matter depends only on your head-piece =)

    This is a truly genious idea! Is this the world's first back-to-back camera, or were you inspired by one you saw somewhere else? Whichever way, it's seriously cool!

    Well, personally I never met such a camera before. But this one is not the first definitely, because I made pinhole cam with two holes opposite each other one year before…

    @jaalvarez, I believe that Lomography has sufficiently strong technical basis to develop and produce toy-like siam-camera. But it is always more interesting to make something with your own hands)

    I´m agree with you ... I enjoy a lot experimenting with my cameras. Perhaps, this one (to experiment) is the best thing in the analoge world in all our analogue World !!

    This is so amazing, maybe you could help some of us who would love to make one of those with some tips or even a complete tipster? It would be nice to know where to cut, how to glue, which traps are hidden in the process...

    Unfortunately, I had been making this camera for a rather long period and haven't made any photos of its construction stages. More over, I can not give the exact instructions where to cut, cause I did the cut in a rough way and then filled the gaps with a special two-part epoxy compound (playdaugh-like glue).
    If you gonna make such a camera on a basis of Smena-8M, to find the approximate area to be cut you need to unscrew the lens, close the back cover and mark the area through the camera shaft. But it is better to make the cut a little bit bigger.
    And one more very crucial tip. It would be much easier to make the "back camera" on a basis of Smena-8m models having dismountable shaft.

    Thanks! And how did you cut? A saw? A Dremel? ...

  31. gndrfck

    firstly drill and then rasp-file

    Brilliant! I have to ask, why is the back lens upside down? Is there a purpose? Curious, ive been brainstorming ever sincr I saw this.

  36. gndrfck

    @crowdizzle the second lens is upside down because of viewfinders
