A photography technique that frequently catches my eye is the use of silhouette - placing a subject directly between a primary light source and the camera. The effect can be painterly or haunting or evocative. It can break a subject down to basic ideas conveyed only by line and shape, where an individual might appear iconic. Collected here are a handful of recent photographs from around the world, where we can only see the outlines of the subject, our minds (and the captions) are left to fill in any details in the darkness
