Again, what we’re looking at is so low res I don’t think we can say the actual shot was under lit. I have no doubt the gun and bullets looked different through the camera viewfinder. But maybe you’re right and it was poorly lit and the bullets didn’t matter to the shot. Given how quickly they were moving a lot of this could easily be chalked up to lack of thought. Maybe they weren’t sure if it was going to be visible, so they had dummies just in case. But more than likely, it looked different on camera.
