A light source for a photographing device comprises a plurality of light emitting devices that emit light of different wavelengths, a power supply device and a light emission control device. The light emission control device controls ratios between light emission amounts from the plurality of light emitting devices of different wavelengths and all the light emission amounts from the plurality of light emitting devices, and turns on and off the plurality of light emitting devices with duty ratios corresponding to the ratios between the plurality of light emission amounts. |
