Want to look “natural”? Try looking out of the side of your face.

Ok, the title of this doesn’t do much for explaining what I mean, so let me try again. I’ve noticed over the years, that there is a little something that can make a model’s portrait shot look a little more natural. I use this for testimonial type of portraits, when you need the model at the camera, but not look staged. I don’t always pull this trick out of the bag, but if I’m having trouble posing a model and the model is having trouble looking natural, I give it a go.
