FILTERS: AN AID IN COLOR-INFRARED PHOTOGRAPHY

It is necessary at times to change the color balance of infrared-sensitive color films in order to obtain optimum results for optimum balance, one application is different from that required for another, or to compensate for changes in the film caused by keeping conditions or process variations. Because of the unique color characteristics of these films, the selection of filters and the understanding of their effects is not as straightforward as with normal- color films. In order to clarify the use of filters and to illustrate how they can be used effectively, descriptions of the filters, their effects on the sensitometric characteristics and on the visual effects in the processed film are described. Viewing filters also can be used to some extent to assist in the analysis of the results obtained. /Author/
