I'm not really what is defined as a "real IMAX screen," but I always assumed the real ones were the much larger screens. Forgive me for not knowing exactly the dimensions, but about 30 min from where I live there is a huge IMAX screen that is like 50 feet tall or something, and I always assumed it was the "real one," yet this same screen is not 1570, it is apparently digital because it is not showing the prologue. Furthermore, according to one of the lists of IMAX screens, there is another IMAX screen about 3 hours from me that is 1570. Whew...this shit is exhausting.
15/65mm is a film format. It measures from 8-12K (thousand) lines of resolution, with an aspect ratio of 1.44:1. Traditionally, 15/65mm screens are 6-12 stories tall. Digital theaters use dual 1.85:1 projectors, having a resolution of 2K. Most digital theaters are retrofit, meaning they were formally regular theaters but were "transformed" in IMAX theaters. They have the same sound system as the 15/65mm theaters, but the screens are typically 3-4 stories tall, and the projectors have a significantly smaller resolution and aren't capable of the IMAX aspect ratio. More and more traditional IMAX's are however replacing their film projectors with digital one's, because it's much cheaper.
