A lighting apparatus includes a plurality of light sources, and a light-source controller. The light-source controller controls the plurality of light sources so that at least one light source in the plurality of light sources can emit assisting light to form contrasts of luminance on a photographic subject, and so that the light sources can simultaneously emit illuminating light to illuminate the photographic subject uniformly. And a photographing apparatus includes the lighting apparatus, a line sensor, and a distance measurer. The line sensor forms image signals corresponding to an image of the photographic subject by receiving the reflected light of the assisting light or the illuminating light reflected by the photographic subject. The distance measurer measures a distance to the subject based on the image signals formed by the line sensor. The line sensor and a high-luminance area formed by emission of the assisting light, cross each other on a plane including the light receiving surface of the line sensor.
