The light for macro photography is designed to illuminate very small objects photographed at close range. When taking such photos, for example of insects, flowers or jewellery, the lens is so close that it often casts a shadow on the subject, making it impossible to illuminate it properly. This type of light is therefore most often attached directly to the front of the lens. This ensures that the light source is as close as possible to the subject and eliminates unwanted shadows. It often takes the form of a "ring light", which encircles the entire lens and provides even, shadow-free illumination, or "double lights", which are two smaller, separately adjustable sources. These allow greater control over the direction of the light and allow shadows to be modelled to emphasise the texture and shape of the subject. Its purpose, then, is to get enough light on a miniature scene and have control over it, which a regular on-camera flash does not allow.
