The selective range of colors and background hues that was possible with this method provided a clarity of the annular growth in the scales not possible with a conventional system. Through color separation the structural detail was enhanced with sharper boundaries that aided significantly in obtaining the information required. Reference terminology of this optical modification covers birefringence, polarization, pseudocolor, non-representational color and others. For qualitative investigation in the laboratory it is a useful technique in the repertoire of the technical photographer.
