Generational Photos
It can be hard to get the whole family to sit still for a portrait, but with generational photos you only need to get them to sit still one at a time, which can usually be accomplished with nothing more than subtle threats. Not only is that easier to manage, but with a little Photoshop magic you can turn the raw materials into a graphic representation of one little branch of your family tree. The finished product is like looking down a long hall of mirrors into your genetic history.
