Many microorganisms when viewed down a microscope move with apparent purpose and towards common goals. The organisms, however,  are fast moving and this makes the use of video difficult when tracking or recording their activity. In this experiment I used neutral density filters, to allow the setting of very long shutter speeds to record the movement of the animalcule  Euglena. What can be seen in the resulting images, are not the microscopic cells themselves, but the tracks that they make by their movement during the long photographic exposure. The process is much like that used by Yuki Karo in her work with fireflies but the creatures in my photographs are many thousands of times smaller. The technique reveals the fenzy microbial  of activity in a small drop of water.
