IMAX Cinematography
Shooting on very large-format 70mm IMAX film, which gives a much sharper, deeper and taller picture. It captures huge scale and small detail in the same shot.
How this film uses it
Nolan shot the Trinity test sequence on IMAX 65mm with practical effects, meaning real photographic and chemical ones. The detonation was captured without CGI, so the explosion looks terrifyingly physical and real.
Where to see it
The Trinity test. First there is silence before the shockwave, then the fire blooms in IMAX clarity. The sound arrives late, and it hits like guilt.
