The ninteenth-century art of shadow photography, as practiced by
W. H. Fox-Talbot in 1834, has been revived by the use of a small-diameter
electronic flash lamp and fine grain film (Edgerton and Wilson 1977; Edgerton
1977a). One practical application has been the photographic recording of
living plankton from freshwater and marine environments (Edgerton 1977b;
Ortner et al. 1979). Exposures of microsecond duration are made after
pouring a plankton sample over a sheet of negative film under darkroom
conditions. The resultant one-to-one silhouette images of these organisms
are without appreciable edge blur, diffraction, or imperfection due to subject
motion and may be identified to genus or species. The technique is
nondestructive and several exposures can be made at sea before preserving
a sample for other analyses onshore.
