This isn’t a trick for getting a more natural shot but is a good trick for when you have people who are uncomfortable being photographed, or state they dislike pictures of themselves. Reverse the image before you show it to them and majority of the time they are way happier with the shot. We’re used to seeing ourselves in reverse as in our mirror reflection.

We did this on a recent shoot for company head shots and the usual candidates who took ages to get a shot they liked were happy first or second time.
