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.

Credits: gndrfck

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)

    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...

  29. gndrfck
    gndrfck ·

    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.

  30. elenya-y

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

  31. gndrfck
    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

    The Infallible Electric Eye

    By far the oddest-looking camera I own, the Electric Eye is an auto-exposure viewfinder camera made by Bell & Howell in the late 1950s. I picked one up online and ended up with another one, that came with a very cool, retro looking carrying case, from my grandfather. It took a little while to try these two out but after running some film I found that this camera is a lot of fun to shoot with.

    Cinematographer Michal Dabal on the Petzval Lens

    Here’s what happens before we interview a photographer. We gush about the work though we have yet to find out the cameras and processes behind the brilliant composition or the light architecture. And even when they haven’t used a Lomo camera, we feature them anyway. But every once in a while comes a pro who uses one of our premium lenses at work and our fun cameras off-duty. This makes us mighty glad, more so when their images are good and worth sharing. We count cinematographer Michal Dabal's work among them.

    Self to the World: The Photography of Leanne Surfleet

    A self-portrait may take root in confidence, extreme shyness or alternate bouts of each. Leanne Surfleet goes through this kind of fluctuation when the camera is all eyes. The attraction—as far as we’re concerned—is the mix of uncertainty and a kind of quiet poise. And here and there, a flash of skin that is more a mystery than full-on revelation. Even Surfleet’s portraits of other people have the same hushed invite, as if to say questions are encouraged. There we took our cue.

    Black and White Photography: The Forms of the World

    Colors may be amped to look unreal, like nothing of this world. Shots may be doubled, cross-processed, post-processed, mixed up into collages. The possibilities are infinite, yet some photographers still prefer black and white. Even in 2016, it is an ode to classic values of precision and balance. Light and shadow must be one pleasing dance. And just like in a well-choreographed piece, forms are obvious or playing coy. It all depends on how you're looking.
