If you are crazy about film and cinematography, then you would (or should) have heard of Christopher Nolan, who brought us Hollywood blockbusters like The Dark Knight (2008), The Dark Knight Rises (2012), and Dunkirk (2017). All are outstanding productions in their own right, but did you know a lot of the scenes – and a whopping 75% of Dunkirk – were shot on 70mm film using Imax cameras?
Now, Imax and 70mm are naturally expensive, just look at the prices that some of the best 35mm film on the market reaches, and you can just imagine how much 70mm from Kodak costs. (Imax 70mm film is shot 1.43:1 with perforations at the top and bottom, not the sides as on traditional film cameras – each frame has about 9x the area of a 35mm image.)
