A meticulous technique, learn to make such microclics after the jump!
This technique is definitely very cool because you never know what will come out and a photo is never equal to another, no matter how much you try. The only detail is that there are few cameras that accept this kind of photography. The most common are the Dianas (mini and traditional) and Holgas (35mm and 120).
The operation is simple and requires no experience: shoot normally, but instead of carrying up to the next frame, only advance one click (hence the name Microclick) and shoot again moving the camera slightly so that the photo is identical to the previous shot. This gives the picture a more loose and spontaneous look.
Now the tips: Never use this technique with high ISO or your photo will come out overexposed for sure. Prefer ISO 100 or less, and try not to shoot in bright sunlight, because the chance of losing the frame is huge.
