I'm doing a short film in a couple of weeks and the first scene has the main character cleaning his gun and preparing for a hit.
The first shot of the film is from the inside of the gun barrel, the cleaning brush slides out which lets the light in and the eye of the character looks down the barrel.
I don't want it to be like the classic James Bond one. I don't need to clearly see the grooves inside the barrel although it could be nice. I'd like it a bit more "natural looking" by just seeing the grooves at the end of the barrel, with the interior completely black.
I am contemplating different ways of doing this shot. I tested a Scott-Towel roll and it felt a bit big. The other problem with cardboard is it can bend and sometimes little pieces of it lift up making it obvious. A 1" pvc pipe might do it if it's long enough. I could try to get a post house to add the grooves on it in VFX. My challenge is to cover the lens with it.
I know the classic James Bond used a pinhole lens to shoot it. I might want to try that with the actual prop gun we are gonna be using, but the cheap pinhole lenses I've seen on sale at B&H seem to be quite soft.
If it can help, we are shooting with a Sony FS700+Odyssey 7Q. Most probably Cooke mini S4 with uncoated front elements.
Any ideas how to achieve that shot?
