Filmswap - Doubles for Sharing

How to achieve accurate filmswaps, to share a roll with any lomofriend.

Many times we ran into these famous filmswaps or double exposures between two people. This means using in two different cameras and exposing only one film.

I tried 3 times to do this, and only with my third try that I had achieved results that made me happy (as they say, third time’s a charm). The first and second time the frames were one over other, and was a little tricky to scan negatives without cropping the photos. Also, many times there was over-exposure, so getting washed out frames are apparent.

But to achieve good results we must consider two things:

1 .- To make sure you’ll be both exposing the same exact frames, mark the square that fits in the filmspool upon loading it in your camera. Mark them with a dark marker. When you replace the roll, you must fit the mark with the hook again. This is so that the second person, or yourself if you will be who makes the second expousure, be guided by placing the roll for the second time in another camera, and frames will fit exactly.
2 .- Set the ISO of the camera at least one f-stop, that is, if your film is 100 ISO, set your camera at 200 ISO. Then develop your film as usual. This is to sub-expose the photos and not to get two photographs overexposed.

It is easier to make a filmswap with cameras with ISO configuration like the LC-A +, but it can be done with anyone, always keep in mind that your shot don’t have to “eat” your partner’s other shot and must be evenly exposed together.

The Filmswap are fun, especially when performed between two people from different countries or cities.

I invite you to find your partner and follow the two tips above to get fun pictures. You can set any theme or just expect surprises.

These photos were taken together with CherieSu, a lomographer from Taiwan. A very nice experience.
