A cinema is a place where movies are shown to an audience. In the earlier days of movie production, films were shown in places such as coffeehouses and tea rooms. As movies progressed and evolved, dedicated movie theaters were built to showcase films. The development of movies has transformed them from silent to sound, and eventually to 3D. Films have also evolved from black and white to color, and from regular screens to widescreens and even dome screens. These advancements have led to significant changes in the design, size, proportions, and audio technology of cinemas. Cinemas must meet the technical requirements for movie projection in order to provide a satisfying visual and auditory experience.
