Schlieren interference patterns are present on the edges of the focal conic fans in this liquid crystalline DNA specimen. The pink color and interference patterns indicate that the specimen is very thick. The DNA concentration for this specimen is approximately 450 milligrams per millimeter, and the magnification is approximately 300x. The digital image presented above was originally recorded on Fujichrome 64T transparency film using a Nikon Optiphot-Pol microscope with crossed polarized illumination. Exposures were recorded about 2.5 f-steps under the recommended value given by an in-camera photomultiplier and were push-processed approximately 1.5 f-steps in the first E-6 developer.
