What is the difference between DMAX and IMAX? Who is better at watching movies?

Difference:

Image maximization is a general term, and there is a DMAX in China called "domestic giant screen". The screen size and projection equipment are a little more standard deviation than IMAX, but the investment is less, so you don't have to pay IMAX.

To put it simply, image maximum (3D) has not only IMAX, but also domestic DMAX and other shanzhai. IMAX works better.

Original invention

Since the birth of the film, people have never stopped exploring and trying to put it on the big screen. Before IMAX appeared, people tried a variety of large-screen projection systems to enhance the visual shock of the film. Due to various reasons such as complicated installation, difficult operation and unstable image quality, it has not been popularized.

Three Canadian inventors of IMAX, Graeme Ferguson, Roman Kroitor and Robert Kerr, also studied the multi-projector large-screen projection system earlier, but their experiments at the 1967 Montreal World Expo were not ideal, and there were many technical problems, which prompted them to turn to develop new single projector and single camera large-screen projection systems, and finally IMAX was born.
