Shadow photography requires a deep understanding of the interaction of light with objects and spaces. Natural light sources such as the sun or artificial light sources such as lamps can be used to create shadows of different shapes and sizes. Long shadows at sunrise or sunset add depth and charm to an image, while strong shadows at midday bring out contrast and fine detail.
Shadow photography isn't just about showing the shadows themselves, it can also be about how light interacts with the surrounding environment. A photographer can use shadow as a tool to highlight emotions and concepts, as shadow can add an element of mystery or drama to an image.
