The evolution of movie making is fantastic. Having the ability to shoot without grain artifacts is a huge improvement in picture quality

I wish they'd up the standard framerate well above 24fps as well (the tech's been there for ages..). To think at one time movies were black and white with no movie sound. We live in great times
Think of some old movie where everything looked like it had freckles or a plague of flies in the sky, when none was actually there.
Director's can still put in grain artifacts, just as they put in colored filters, etc if they choose. Grain artifacts are the result of the dated technology and directors have far superior tools now like the RED.
