Segnalo in particolare questo passaggio particolarmente esilarante:
E questo relativo ai valori target di contrasto dei sistemi laser (in funzione da metà 2014 pare di capire):we have microphones permanently mounted within our venues that listen as if they were your own ears as to what's going on. It will give us an alert if something's not right and we can remotely tweak the tuning in the theatre [from IMAX headquarters].
Okay, so here's your reference. Today most digital projectors out there are around 1800-2000:1 [contrast ratio], or in that range. IMAX, through what we're doing today [in 2013], is at around 2500-2800:1, so we're higher than everybody else. IMAX projection film is in and around - you know, there are always variables that play into how well the system has been set up - the 4000:1 range, give or take. IMAX laser is going to be double that, at around 8000:1.
