Photographing couples can be great fun. It can also be a great big pain, especially when you are faced with a couple that have a pretty drastic height difference between them. The common tactic is to simply hunch the taller person over to match the height of the other. It’s not a very flatting look, and doesn’t really make for great photos, but it’s just a natural reaction.
Peter Hurley’s approach is a simple one. “Spread ’em”. The problem with having the taller person simply lean down is that it brings the shoulders forward, it shortens the neck, and just looks plain uncomfortable. Spreading the legs allows your subject to lower their height, while still keeping their torso and neck elongated and their head held high.
