What does low-key photography mean?
Low-key photography is characterised by dark, dramatic and often moody images with loads of shadows. Basically, it is a dark photo with few highlights/light tones. One of the more common ways of achieving this in wildlife photography is to find an animal in good light but with a dark background. For example, a rock face or a dark forest in shade. Of course, this is easier said than done sometimes. Find this and under-expose the image to darken the background even further. Voila!
