| Description | Microfilms and processes suitable for microscopying black-and-white films from the Earth Resources Aircraft Program were selected. A further purpose was to chose duplication materials which are suitable for multiple generation copies for economical dissemination to satisfy index and reference purposes. The basic requirements are that the gamma of the negative film and the overall system gamma of the multistage duplication process should be near unity, and that there should be sufficient resolution to reproduce the major salient image features of the original 9 1/2-inch format film. |
