IMAX Digital
A digital version of IMAX started rolling out in 2008. The new system is a projection standard only; there are no digital IMAX cameras.
Digital IMAX systems can show either normal or 3D content in DCI or IMAX digital format (which in itself is a superset of DCI). Being a digital system alleviates the need for the use of bulky film reels and facilitate inexpensive distribution of IMAX features, the more compact nature of digital equipment means the system can fit inside a normal multiplex cinema complex rather than the specialised buildings IMAX normally requires.
Despite those advantages, one big disadvantage is the resolution of the picture is much lower than normal IMAX. The screens used by digital IMAX installations are also much smaller (28x58 feet) than those found in traditional IMAX cinemas. Despite these facts, the digital installations are marketed simply as IMAX, drawing no distinction to the traditional 15/70 IMAX – much to the dismay of 15/70 IMAX cinema owners.[5]
