You’re wrong! It has

a magenta cast to it

Off-the-shelf not good enough. 12-bit color & security required.

Rolling It Out

22


The Digital Cinema Rollout:

ReplacementTechnology

23

DebtSavings

Distributor Exhibitor

Capital

Subsidy

VPF


Institutions Driven by the Digital Rollout

Digital Cinema Initiatives (DCI)=> Common Specification among Studios necessary to stimulate R&D and gain support from the Finance Industry

SMPTE => Industry Discussions over Technology (not so much standards - only 40% of SMPTE cinema standards in regular use)

No institution has authority over rollout of new technology

24


In Summary…

HDR for Cinema is not simple.

Technology is changing. Too early to establish targets.

Rollout cannot rely on institutions. Different thinking is needed to address capital investment and technology.
