6dmsd6 | how do filmmakers film close-up gunfire? | I was watching the season finale of Arrow and it got me thinking so spoilers for that. When Chase puts a gun to his head and fires, how does one film that safely? Blanks are known to blow the heads off snakes at 6ft range (granted that's a rifle round) so surely it's not that. Is it just cgi? What about before that? | explainlikeimfive | https://www.reddit.com/r/explainlikeimfive/comments/6dmsd6/eli5_how_do_filmmakers_film_closeup_gunfire/ | {
