To date, examined evidence of color perception deals with pigments of low reflectance values, and as evidenced with increased depth, decreasing light level, plus water density, rapid absorbtion of the infra unit occur (ie. color rendition S.P.I.E. February 1967, E. Brooks II). High reflective units are revealed in this paper to determine added efficiency to the recording underwater observer and camera receiver. Ambient levels to low and high pigments in close and extended distances. Supplementary lighting evaluation on targets utilizing quartz iodine, thalium iodide, and magnesium for evaluated image enhancement and increased color penetration of the water barrier on large targets equaling 80 square feet of surface.
