Applications of color infrared photography to turfgrass science1

  1. G. M. Wood

Abstract

Ektachrome Infrared (IR) 35-mm reversal film was compared with true-color (TC) reversal film for photographing, at normal camera range, the results of turfgrass experiments. The principal advantage of IR film was the increased pictorial contrast obtained. Techniques, results, and use of IR film are discussed and illustrated. Some fundamental IR theory is presented. Additional index words: Electromagnetic radiation, Wavelengths, Near-infrared, Visible spectrum, Spectral reflectance of grass, Solar radiation, Erysiphe graminis, Lolium perenne, Poa pratensis.
