1. A method of capturing digital images, comprising:

  • determining a frame latency for an image processing pipeline of an electronic device;

    measuring, using the electronic device, ambient light in an environment during a pre-flash phase;

    determining, using the electronic device, a flash intensity based on the measured ambient light during the pre-flash phase;

    determining, using the electronic device, a sustain time for a flash phase during the pre-flash phase;

    determining an image capture time based on the frame latency and the sustain time;

    emitting light in the environment during the flash phase at the determined flash intensity for a period of time corresponding to the sustain time; and

    capturing a digital image within the environment based on the determined image capture time.
