Imax is a format used by the motion picture industry with the ability to record and show movies of larger capacity and resolution. A regular Imax movie screen is seventy two feet by fifty three feet. It is not the only sized screen used but it is the average. Their theatre construction is far different than the old movie houses we used to visit. The film size allows audiences to be much closer to the movie. They also design in the form of domes with all seating rows relative to one screen height. The rows of seats are angled so that the viewers are directly facing the screen. “IMAX designs, leases, markets, carries out maintenance and operation of all of its Imax film and theatre systems. They are responsible for the development, production, post production and distribution of all IMAX pictures.” the system was developed by Graeme Ferguson, roman Kroitor, Robert Kerr and William Shaw. When they began they found a multitude of problems with what they were trying to present but, over time they began to smooth the process out. IMAX increased movie resolution by moving toward larger film framing. They did this by utilizing 65 mm film run horizontally in cameras. IMAX got five hundred times the resolution that were in older film productions. Another innovation was their use of the separated sound track. They use a multi channel 6 track sound source that is based on SMPTE time code. This time code can be added to film and audio material. It provides excellent time referencing. IMAX is only beginning. They will be introducing a brand new 3D camera within the next two years. IMAX technology was not accepted at first glance. There were many bugs that needed to be worked out. Now that most of them have been worked out, IMAX is leading the way in motion picture films. |
