Big screen experiences
IMAX cinema at the Science Museum
Watching films in theatres or homes is always an enjoyable activity. However what if you had a chance to jump into the film, to feel as if you are a part of the action, or delving into the human body. What if you had the chance to travel through your digestive tract, or into a world of computer animation? The London Museum of Science??s IMAX or Image Maximum theatre allows you to do just that.
In a room with a screen 20 m high and 26 m wide it is easy to feel a part of the film. However it is technology and not just the screen that allows the film to come to life. With a combination of specially made projectors that run the same amount of frames as a normal projector (24) but nearly 4 times as many feet per minute as a 34 mm projector.
The sound system is unique as well, played on a DVD which controls the projector and the sound in a system called DTAC, (Digital Theatre Audio Control) which transmits sound through an amazing 11,600 watts of power.
And if that??s not intriguing enough the camera in itself is impressive as well, not only does the IMAX camera only hold 3 minutes worth of film ( 13 reels for 40 minutes), but there is also a 3D camera as well which involves the audience even more. 3D cameras involve simultaneously running two films through polarized lenses spaced equivalent to that of your eyes (the interocular distance). Once the viewer puts on their polarized glasses the images are life like and right in front of your eyes.
