Spectral sensitivity of photographic emulsions

he photographic meteor magnitudes are still in use, and it is important to link them to magnitudes determined with modern detectors. Photographic meteor magnitudes were determined from meteor images registered on photographic film or plates. The spectral sensitivity of various photographic emulsions differs quite a bit, and it is seldom possible to get accurate information on the particular type of emulsion used. The main types of emulsions are analyzed and their average spectral sensitivities recalculated to equal-intensity light, as is usual today. The implications on magnitude determinations are discussed.
