Either the flash is firing too late or the shutter speed is too fast (shutter moving vertically). Note the different exposure levels. In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor.

Electronic viewfinder interchangeable lens camera. See also MILC, mirrorless interchangeable-lens camera. [16] Exif: Exchangeable image file format. A standard format for tag data in digital camera files. [10] f: f-number, f-stop. The numerical value of a lens aperture. The ratio of the focal length of the lens divided by its effective aperture ...
A Nikon-style mode dial showing aperture priority mode.. Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.
Cameras with focal-plane shutters—even if they had PC connectors with X, F, M, or S-sync delays ("xenon sync" with zero delay and flashbulbs with peak delays of 5, 20, and 30 ms)—could not be used at speeds that attenuated guide numbers with most types of flashbulbs because their light curves were characterized by rapid rise and fall rates; the second shutter curtain would begin wiping ...
In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at its minimum desired value, then, when shutter speed reaches the user-defined limit, the ISO is increased, up to the maximum value. [5] All of the above functions are independent of lens focus and stabilizing methods.
The f-number N is given by: = where f is the focal length, and D is the diameter of the entrance pupil (effective aperture).It is customary to write f-numbers preceded by "f /", which forms a mathematical expression of the entrance pupil's diameter in terms of f and N. [1]
Image stabilization on digital cameras or lenses can often permit the use of shutter speeds 3–4 stops slower (exposures 8–16 times longer). [citation needed] Shutter priority refers to a shooting mode used in cameras. It allows the photographer to choose a shutter speed setting and allow the camera to decide the correct aperture.
In manual mode, a black needle points out the shutter speed recommended by the built-in, open aperture, through-the-lens (TTL), silicon photodiode (SPD) light meter, with 60/40 percent centerweighting, while a translucent green needle shows the actual camera-set shutter speed. The photographer adjusts the shutter speed and/or the lens aperture ...
