8mm Film

8mm is the smallest gauge people shot on, so the grain is the largest thing in the picture. Detail dissolves into it, and a face reads as a shape with a colour rather than a set of features.

That loss is what makes it feel like a memory. The format cannot hold enough for a viewer to study, so the mind finishes the frame.

The frame is about five millimetres wide and close to square. Blowing that up to a screen magnifies every grain of the emulsion with it.

The cameras were spring wound and silent. A shot runs for as long as the spring holds, usually under thirty seconds, and no sound was ever recorded with the picture.

The film ran through a simple gate, so the frame drifts and shakes a little. That drift is called gate weave, and it is one of the strongest signals of the gauge.

Use it for a memory, for a scene set before 1965, and for footage that is supposed to have been found rather than shot.

Skip it when anything in the frame has to be read. Text, faces at a distance and small objects all vanish into the grain.

Super 8 came later and gave the same strip a larger frame with smaller sprocket holes. It holds more detail and its colour is brighter.

The test is the frame shape and the detail. Nearly square and barely legible is 8mm. Slightly wider and readable is Super 8.

The most studied piece of 8mm footage ever shot is Abraham Zapruder's, filmed in Dallas in 1963 on a spring wound Bell and Howell camera. Twenty six seconds of silent colour film became the record of an assassination, and every copy of it carries the grain and the weave of the gauge.

The model returns clean widescreen footage with a grain filter over it. Ask for the nearly square frame, and say the grain sits in the image rather than on top of it.

The other failure is too much detail. Say the detail is soft and the texture coarse, so the format looks like the reason rather than an effect.
