Double exposure plotted portrait of a model composed of black and blue lines that wobble to mark out darker areas within the image.

In this double exposure image, the model posed twice. The clothed pose is drawn using blue horizontal lines, and the nude pose using black vertical lines, which wobble further from the centre point in darker areas.
