The extraction and characterisation of information from photographic emulsions is the subject of this review. Since the major Schmidt Telescope full sky surveys form the bulk of the photographic emulsions currently under intensive study, I will limit my remarks to them, although most would be applicable to any of the emulsions now in use. A listing of the major direct imaging surveys is given in the article by van Altena et al (1993).
