Color photography has added a new dimension to the field of remote sensing and its application to natural-resource exploration. The color differentiation allows the photogeologist to go much further in the details of his interpretation than he could with black-and-white photography. Additional structural implications also can be mapped. In the mineral field, color anomaly evaluations have proved valuable.

Color photography has been used successfully in exploration for uranium, coal, and base metals, as well as oil and gas. It has become an important detection tool in the fields of ecology and environment. Maximum use has been in the mineral field, although I feel there is more use to be made by the oil and gas industry if color photography is properly applied, and it certainly will be applied more to detect ecologic problems.

Color photography has not had widespread use outside the United States; however, I feel that this will be remedied in the near future. Part of the problem is lack of first-class processing and printing facilities in many countries. Regardless of all the other more exotic remote-sensing methods, I believe the future will see a tremendous increase in the use of color photography in many fields.
