HSS allows greater flexibility for using light during fast shutter speeds, regardless of ambient lighting or for portraiture outdoors. These two images were shot using HSS, one at 1/6400 to create the dark background and the other at 1/8000 to freeze motion. Because the flash is actually sending out hundreds of pulses during the exposure to ensure the entire sensor receives light, the power is significantly reduced and the subject to flash distance has to be very small (inches in the case of the hummingbird).
