A method, system, and computer program product controlling flash behavior of a camera during capture of image data. The method includes identifying a target object from among a plurality of objects in a current scene. The method further includes determining whether a distance to the target object is within an effective flash range associated with at least one flash module of an image capturing device. The method further includes measuring, via at least one camera, an ambient light level within the current scene and comparing the measured ambient light level to a predetermined flash light threshold. The method further includes, in response to determining the target object is within the effective flash range and the measured ambient level is less than the predetermined flash light threshold, triggering at least one flash module of the image capturing device to illuminate the current scene during capture of image data by the at least one camera.
