Resolution and image brightness are maximized if a cone of illuminating rays is incident on the specimen. The contrast of fine detail can be enhanced by artificially and selectively operating on the characterizable properties of the oblique illumination, relative to the normally incident component. 

Rheinberg differential color contrast (22.231. in which the normal and oblique illuminating rays have different colors. Fine detail in the image of the specimen appears with a color different to that of the coarse detail. This technique maximizes illumination, and is useful when attempting to highlight disclinations without loss of intermediate detail. It appears to be a novel technique in the context of liquid crystalline microstructures.

The wear of the rider specimens was determined by measuring the diameter of the wear scar and by calculating wear volume. Data reported are from typical runs selected from several repeated experiments. The specimens were carefully studied and photographed at low magnification using oblique illumination.
