Abstract
An illuminator for a digital camera includes a body of transparent material defining a cone shaped cavity with an opening at the apex of the cone for a taking lens of the camera and an opening at the base of the cone for locating an object to be photographed with the digital camera. A plurality of light emitting diodes (LEDs) are uniformly distributed throughout the body of transparent material with respect to the surface of the cone. A power supply applies power to the LEDs so that their brightness' are equal.
