Abstract : The objectives of the program were to determine the relative usefulness of color photography in aerial reconnaissance as compared to panchromatic photography, and to make appropriate specific recommendations for application of color photography in aerial reconnaissance operations. No decisive advantages for either type of photography were found in the test program. Use of color imagery increased the speed of interpretation in both search and analysis tasks to a modest degree, and caused a small improvement in completeness in search tasks where hue was a factor differentiating target from background. However, accuracy of analysis of color photography tended to be lower than that for panchromatic when photo scale was small or marginal in relation to target size. Application of color photography is recommended in reconnaissance situations where color is expected to be a strong clue to desired information, small time savings are significant, and collection of medium to large scale imagery is feasible. Investigations of ways and means of increasing the modest advantages found for color films are also recommended.
