Cinematic critic Lev Manovich has analysed the techniques of digital cinema and has argued that contemporary digital cinema is marked by pre-cinematic movement of image techniques which shows a return to earlier cinematic methods. Contemporary digital cinema seems to be characterised by interactive narrative (Manovich, 1996). Manovich however claims that the digital media helps to present narratives in a new way yet considering the discussion of the central focus of digital media, narratives according to Manovich is far from the essential element of digital storytelling (Manovich, 1996). Digital cinema seems to have redefined the identity of cinema as with digital cinema, simulation of all real events could be done without necessitating real physical space events to occur and be recorded within photographic limitations.
Cinema has been seeing what is widely called a digital revolution in which the computer is used more extensively to create fictional forms and moving images in a specialised manner. According to Manovich the essence of cinema is in 'recording and storing visible data in a material form' (Manovich, 1996). Just like a computer, a film camera records cinematic data onto a film and the film projector reads it as the computer is controlled by a program and records input data. To show the essential similarities between the cinematic process and the recording of data in a computer, Manovich has claimed that digital cinema thrives on these similarities as in case of cinematic techniques; distinct mages are recorded in celluloid strips whereas in case of the computer, data is stored electronically in the form of a binary code (Manovich, 2002). A programmed computer however has been processing images and visual data even before it could process numbers. Manovich explained the relationship between a modern digital computer and the modern media to suggest that the synthesis of the two has led to the creation of the digital media. A digital computer is capable of performing calculations on numerical data more efficiently than mechanical equipments used earlier and along with the technological advancement of the computer since Turing machines, the modern media has changes in its technical aspects with regard to storage of images, processing of image sequences, sounds and text editing. The photographic images stored in the film can now be converted to numerical data which is made accessible through the computer. This has led to the rapid and successful creation of the elements of digital media such as graphics, sounds, moving images, shapes, spaces, texts, and computable data (Manovich, 2002).
The digital concepts of random access, sampling, database etc are all applicable to the digital media and along with the computer, cinema has aided in manipulation of time and space, ad reduced reality in to a moving image with mechanisation of visual events (Manovich, 2002;
