Abstract
  • A photographic band-ratioing technique was investigated. The data source consisted of 70 mm Landsat Multispectral Scanner (MSS) negatives. The process would require combining registered positive and negative transparencies to achieve a ratio modulation in the resulting print. This would also require compensation for atmospheric effects on the original negatives by special photographic processing. Results indicate an inability to easily correct for atmospheric effects photographically. This was due exclusively to low intensity reciprocity failure. Procedural revisions could include the use of a custom light source, the selection of a different emulsion, the hypersensitization of the emulsion, or some combination of these. Related work could include a less theoretically strenuous application of positive-negative masks for target enhancement.
