9. Old photographic sensitivity to light was low, slow

Often you had to open the shutter, and expose the photographic material to light for some time. Even for more than a full minute. As in modern "time exposures."

And so if anything moved in that period, it blurred, faded. Or if it moved pretty fast? It would never appear in the negatives or final pictures at all.
