Abstract: An apparatus and method for capturing an image on an electronic device having a flash comprising a first light source and a second light source is presented herein. A detection of a color spectrum of ambient light is made using image data sensed by an image sensor of a camera module. Additionally, a determination of an intensity of a first light when combined with an associated intensity of a second light results in a color spectrum that substantially matches the color spectrum of the ambient light. The flash emits a first light from the first light source of the flash and second light from the second light source of the flash. An image from a camera module is recorded during the emission of the first and second light.
