I'm just a hobbyist filmmaker. I have no aspirations to enter the professional filmmaking world. My highest hope is to someday have a short that will be shown on a movie screen to an audience at some film festival. So keeping that in mind, this is my question.
I caught a preview screening of "One Spoon of Chocolate" a few days ago. There's always something I find to like in any theatrical release, and with this one I paid attention to the graininess of the film on screen. It was shot on 35mm. A few weeks ago I also attended a screening of the original The Evil Dead, and that was even grainier, but it was shot in 16mm.
I found a grain filter in the editing program I've been using, and after checking it out, I to agree that it makes the short I'm currently working on look better.
HOWEVER, I realize that the screen size I'm working with, a typical iPad, is significantly smaller than a theatrical projection screen. When watching the trailer for One Spoon if Chocolate on my phone, the grain is far less apparent.
I don't have access to a large theatrical front projection screen. Am I correct in guessing that a little grain can go a long way, that if it's barely visible on an iPad, that it will still be highly visible in a theater?
