Thought this might be of interest for some.
I have seen the IMAX resolution numbers thrown around at 18K. But other places, and in this blog it seems more like in the 8 - 9K ballpark.Mark Wilson
There are 26 IMAX film cameras in the world today. At IMAX HQ, I got to play with 4 of them (and take plenty of photographs for you).
With an Epic 645, and the coming JVC 8K or E&S 8K laserprojectors (if they give enough lumens) should it not be possible for IMAX to go all digital without compromise too much on image quality?
ps; something I found looking for something else; Delivering 8K VFX Shots for The Dark Knight.
