Abstract. The quality of the images of objects in an open area depends on the state of the atmosphere (the presence of atmospheric formations, mainly hydrometeors). This study examines the increase in contrast by converting the dynamic range of the image brightness based on the evaluation of the absorption coefficient of the atmosphere.

Key words: hydrometeors, digital images, dynamic range, contrast enhancement, improved distinguishability of objects.
