Abstract
Various methods, apparatuses, and systems in which a digital photography device includes a rolling shutter, a sensor, and a flash are described. The sensor implements a rolling shutter timing mechanism. The shutter includes a material that has an alterable translucent state. The shutter is in the optical path of light going to the sensor. The flash generates a pulsed illumination. The alterable translucent state of the shutter controls the sensor's exposure to the photographic effects of ambient light during a picture using the pulsed illumination.
