(Article Trader) – The modern cinema has come a long way in the last hundred years since film was first invented. Where once films were shown in dark, single screen movie theatres with flickering images projected onto screens, movies have evolved to the grandiose experience they are today. Most cinemas now are huge sprawling multiplexes that show dozens of movies at the same time, entertaining thousands of people at once. Then once the films have gone from the cinemas they are released on home entertainment formats such as Blu-Ray and DVD.
IMAX is one such advancement in films that has transformed the cinema-going experience to create much larger screens with higher resolution movies being projected onto them. Film shot for IMAX is shot on larger 65 mm film which is then run through the camera horizontally. This means that the IMAX film image is 69.6 mm wide and 48.5 mm tall, instead of the normal 48.5 mm wide and 22.1 mm tall.
The film is then run through the camera three times as quickly in order for it to be exposed at 24 frames per second.
Several films these days contain scenes that have been shot specifically for display on IMAX, such as the new Transformers sequel, Transformers Revenge of the Fallen, which features three scenes shot for IMAX.
