danny_boy: Where did you find the following?

Peer reviewed International studies conducted in theaters across the globe concluded that the average release print has roughly 500-800 lines per picture height.

This seems very wrong to me, so please provide the necessary citation(s) if you're claiming that it's correct.

 

 

Film theoretically has very good resolution capabilities. What is delivered to the theatre is another story. If we believe the ITU tests, then images captured at almost 2400 lines per picture height on the camera negative deliver significantly degraded on screen resolution through the projection system – in the range of 500 – 800 lines per picture height. 500 lines corresponds to about 9 line pairs per degree from 2 screen heights.
