The areas in shadow are void of detail so they contribute little. We use flash in daylight to soften shadows. This technique is called "fill flash", because the light from the flash fills in the otherwise dark shadows. | |

| Jul 20, 2017 at 16:48 | comment | added | Alan Marcus | @ Digital Lightcraft --- You are spot on -- Modern flash units emit a pre-flash or otherwise meter the subject using data gleaned from the camera’s chip logic. The idea is to automatically adjust the power of the flash so an over or under exposure is circumvented. Because the exposure is an accumulation of light energy over time, one of the best ways to control the impact of the flash is to custom alter the length of the blitz. Thus the photographer is not in full control, the hardware and software of the flash take command. | |
