COLOR & COLOR-IR FILMS FOR SOIL IDENTIFICATION

EKTACHROME INFRARED AERO FILM 8443 (EIR) AND KODAK EKTACHROME AERO FILM 8442 (CC) WERE TESTED FOR USE IN IDENTIFYING SOIL TYPES. TWELVE AIR-DRIED SOILS, DIFFERING IN MUNSELL COLOR DESIGNATIONS, WERE PHOTOGRAPHED WITH THE CC AND EIR FILMS. OPTICAL DENSITY MEASUREMENTS WERE MADE ON FILM TRANSPARENCIES WITH A DENSITOMETER USING RED-, GREEN-, BLUE-, AND WHITE-LIGHT BAND-PASS FILTERS. DUNCAN'S STATISTICAL TEST INDICATES THAT THE SOILS CAN BE SEPARATED INTO TWO GROUPS: SOILS WITH A LOW CHROMA (SOILS GREY OR NEUTRAL IN COLOR), WHICH ARE DISTINGUISHED BEST WITH EIR FILM, AND SOILS WITH HIGH CHROMA (SOILS WITH HIGH COLOR), WHICH ARE DISTINGUISHED EASIEST WITH CC FILM. OPTICAL DENSITIES MEASURED USING RED FILTERS DISCRIMINATED BEST AMONG LOW CHROMA SOILS, WHILE OPTICAL DENSITIES OBTAINED WITH BLUE FILTERS DISCRIMINATED BEST AMONG THE HIGH CHROMA SOILS. /AUTHOR/
