What makes the difference between the Riverfront Park IMAX Theatre image vs. other area theatres? The 70 millimeter IMAX film used in our films are 10 times larger than the standard film used in standard theatres. Each film frame is 3 inches by 2 3/4 inches. Each frame is pulled through the projector at 24 frames per second thus providing a much higher quality image presentation. These images are then projected onto the screen via a 4,500 watt Zenon lamp. There is conjecture that if this lamp were turned on uncovered outside of the IMAX theatre, it would be bright enough to be seen in space. The final images are presented onto a screen which is over 53 feet tall by 69 feet wide.
IMAX film does not include an embedded soundtrack as do other film theatres. A separate digital 6-track recording is synchronized to the film frames. These audio tracks are played directly off a hard disk drive which is then distributed directly to the amplifiers rather than using a decoding method, such as Dolby Digital. The audio is then presented via our six speaker system producing a three dimensional effect. This method of production accounts for our higher quality sound experience.
The Riverfront Park IMAX theatre also has assisted listening devices available for persons with hearing impairments. Our wireless system offers both standard wireless receivers with Ear Speakers and “T” coil neck loops for patrons with applicable hearing aids. Please consult our staff at the concessions counter for assisted listening devices.
Incidentally, the term IMAX stands for Image MAXimum.
