This paper discusses the issues of characteristic curve restoration for astronegatives exposed in the wide range of expositions in U, B Johnson color bands using different telescopes. Photographic plates are digitized by Epson commercial scanners. Digitized images are processed in MIDAS/ROMAFOT software. The accuracy of characteristic curve restoration using photoelectric data is in the range 0.1-0.2m.
