  • Digital movies have three meanings: movies that include computer images, movies that are produced and edited digitally, and movies that are screened and distributed digitally. Since the mid-1970s in Hollywood, digital films expanded and developed in earnest as they were regarded as an extension of a commercialist aesthetic, and have become common in almost all genres. Digital cinema raises the epistemological problem, especially the realism problem of cinema in terms of a direct relationship with reality.
  • Digital technology which began to be used in movies in earnest after the 1990s, has become the most important factor in all stages of film, including planning, production, distribution, and screening. Since movies are highly dependent on technology and the production process is a complex medium, digital technology elements are included in almost every step from planning to screening and further marketing, and each person who uses the term refers to only a specific area or element of the film, so the concept is defined. While it is controversial to do, digital cinema is generally used in three uses.
