Abstract
An illumination device for photography which can photograph an image expressing a movement of the object is provided. The device comprises a light emission unit which emits, continuously and at an constant emission amount, an illumination light, and a light emission control unit which controls the emission unit and changes a light emission intensity during the acquisition of a single still image by exposing object light on an imaging unit provided in a photographic device, wherein the light emission control unit, during the acquisition of the single still image, causes the illumination light to emit continuously at a first light emission intensity in a first time period, and causes the illumination light to emit continuously at a second light emission intensity with a lower intensity than the first light emission intensity in a second time period after the elapse of the first time period.
