I know some of you really dig that gritty film look. If you shoot digital too, try shooting a few stops under exposed and then bringing it back up in post. If you shoot underexposed, when you bring it back up in post, it can add a gorgeous texture into your image. Try experimenting with how much you underexpose because it will change how the grit looks when you bring it back up. Also, if you use a higher ISO (2,000+ on the 5D III and 6,400+ on the 5D IV), the grit will start looking more and more rough and possibly more digital if you bring it up to far. In short, test it. Every camera will react differently, every type of light, etc. If you're into it, test and play! If you're not, why are you still reading this ya dingus?
