[QUOTE="Felisek, post: 411333, member: 23887"] The first shot (without the flash) is a demonstration that the ambient light is so underexposed (in manual setting 1/250 s and f/16) that it creates the black image. Then, we turn the flash on and take another shot. Background is not affected by the flash, as it is not illuminated, so it stays black. But our subject is illuminated and if the flash is powerful enough, it will create enough light to have a portrait against the black background. [/QUOTE]
