Two methods of spectroscopy of meteors using image intensified video cameras and classical photographic film
cameras are compared. Video cameras provide large number of low resolution spectra of meteors of normal
brightness, which can be used for statistical studies. Large format film cameras have been used through the history
and provide high resolution spectra, which can be used to derive temperature, density and absolute abundances of
various elements in the radiating plasma. The sensitivity of films is, however, low and only spectra of bright
meteors (fireballs) can be studied. Examples of photographic fireball spectra are provided.
