Recently I've been approached by different news organisations to comment on deepfaked images and videos. In most cases they already know whether the thing is a fake or not, but they want to know why. It's been a pretty fascinating thing to be tasked with, honestly, and some of the examples completely caught me by surprise (warning: Daily Mail link). Many of us see faked images on a daily basis now, but there's not a lot of writing about how fakes are detected other than one-liner folk knowledge on places like Twitter. I thought I'd write a bit about how I approach the problem.
