The lens has nothing to do with the size of the film. 70mm means the film is 2 inches wide, 35mm mean 1 inch wide, 16mm is 1/2 inch and 8mm is 1/4 inch wide film. 70mm also has no bearing on the resolution either, that is controlled by the precision of the lens grind and the grain size of the chemical emulsion.
When film (any width) is scanned for adding digital special effects in a Kodak workstation, it is with 4096 horizontal scan lines (thus the original meaning of the term 4k). 4096 scan lines on the big screen is not discernible as digital imaging by the eye, so it blends perfectly with conventional shot analog film. Both Panavision and Arriflex offer full digital cameras for the Hollywood film industry.
Consumer cameras of the "4k" ilk only shoot 2080 scan lines, so there is no 'fix' to make them full theatrical quality, but if the entire production is shot at that resolution and not mixed with actual 70mm or 35mm film footage, it is not likely to be much of a distraction. If the movie is distributed as a DVD, then the viewer won't be able to tell the difference between a 70mm film original and one produced on MiniDV!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
