NOAA Photo Library Image - fish7948

Density and color enhancement of photograph of fish school and contrail by Philco Ford for BCF. To enhance readability of original photograph, which conceals many details, each subtle tone is assigned a color. This and other advanced techniques makes it possible to identify fish schools, changes in plant life in water, water depths, and polluted areas. See images fish7971 and 7972.
