The authors present an analysis of a stellar field in the disk and inner halo of the Large Magellanic Cloud. The BV photometry is based on electronographic exposures with photoelectric calibration. A high degree of interactivity is involved and 23rd magnitude in the very crowded field is reached. Problems of point spread function generation, of image disentangling and of background correction have been studied in some detail. The colour-magnitude diagram shows presence of a halo population as well as a young disk population. The luminosity function has been compared to that of the solar neighbourhood showing similarities but also indicating that the disk thickness in the LMC is the same for stars between Mv = -3 and Mv = +1.
