813 EFFECT CF FLYING HEIGHT ON THE COLOR OF TARGETS IMAGED ON COLOR INFRARED FILM 1 / Jack H. Hansen University of Missouri-Columbia, U. S. A. ABSRACT Color shifts associated with three flying heights above the datum, namely 1500 feet (460 m), 6000 feet (1800 m) and 15000 feet (4600 m) are analyzed on two flight dates. Color meas urements of imaged red, green and white targets on color infra red film are made with a Leitz MPV microspectrophotometer and specially written computer programs with color descriptions given in 1960 CIE-UCS u,v uniform chromaticity scale coordin ates. Color differences are statistically analyzed and anal ytical densities are determined. The hue of all imaged tagets shifted toward blue-green with increasing altitude when the exposure was consistent with the Kodak recommended decrease in exposure for increasing elevations. Generally, value and chroma decreased with increasing altitude with differences in the effect ive film exposure contributing to variations. Film exposure differences caused target reflectance related color shifts, therefore strict exposure control must be maintained where color comparisons between different flights will be made. Also import ant to photointerpreters is the color similarity found between the imaged targets on photography taken at the same altitude but on different dates. This suggests that photography flown on different dates may be compared directly, altitude for altitude, when taken under similar atmospheric conditions, exposure and time of day. ZUSAMMENFASSUNG Farbschwankungen verbunden mit drei Flughöhen, nämlich 1500 Fuss (460 m), 6000 Fuss (1800 m) und 15000 Fuss (4600 m) werden für zwei Flugdaten analysiert. Mit Hilfe eines Leitz MPV Mikrospek trophotometers und eines speziell entwickelten Computer-Pro grammes, dessen Farbbeschreibungen in CIE 1960 u,v einheitlicher Farbenskala gegeben sind, werden Farbmessungen der auf dem Infra rot Farbfilm rot, grün und weiss abgebildeten Objekte gemacht. Farbunterschiede werden statistisch analysiert und analytische Dichten werden bestimmt. Die Färbung aller abgebildeten Objekte verschob sich mit zunehmender Höne zu blau-grün, wenn die Belicht- J. H.
