Using a Sony A7IV, I did a full nighttime engagement shoot on the streets of Atlanta. This was different from photographing wedding receptions and indoor shooting with dim lights. That meant working with a speedlight, sometimes paparazzi style, and a higher ISO than usual. That may sound daunting, but guess what? A powerful camera such as an A7IV makes everything a breeze. The highest ISO I used was 1000, and that too on a very dark bridge.
