The Society for Optics, Acoustics, Motion Pictures and Theatre Technology (OPAKFI) was founded in 1933 by the professionals of moving pictures: filmmakers, distributors and exhibitionists. Because this is a parallelly technical, technological and content creating industry which keep alive only by the film spectators, at this domain are close connected the technological development and the knowledge of the actual social situation.  Our renewed team works in the spirit of this complexity. At present the main territory of our activity is the digitalization. We participate in congresses, make scientific searches and publications and are occupied with the modernization of vocational trainings.
