A leaf shutter " Prontor " has its origins in the Italian word "pronto", meaning ready (and was a leaf shutter made by Alfred Gauthier [ de ] ). [ 3 ] " Compur " is derived from the word "compound" (the " Compound [ de ] " was a long-lived series of leaf shutters made by Friedrich Deckel ).
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.

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.
One technique to make this easier to control is called back button focus: separating focus from the shutter control button by reassigning the AF-on function to a button on the back of the camera body. [8] Some models of a camera may have a dedicated AF-ON button, and menu options to disable the focus via shutter button half-press.
The first camera to feature through-the-lens light metering was by Japanese company Nikon, with a prototype rangefinder camera, the SPX. The camera used Nikon 'S' type rangefinder lenses. [1] The Japanese company Pentax was the first manufacturer to show an early prototype 35 mm behind-the-lens metering SLR camera, which was named the Pentax ...
On a sunny day at ISO 100 ("100 speed film"), the aperture is set to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [2] seconds (on some cameras 1 / 125 second is the closest available setting to 1 / 100 second). On a sunny day at ISO 200 and aperture at f /16, set shutter speed to 1 / ...
This camera has a fixed shutter speed, so the "EXP VALUE" ring simply sets the aperture. On most cameras, there is no direct way to transfer an EV to camera settings; however, a few cameras, such as some Voigtländer and Braun models or the Kodak Pony II shown in the photo, allowed direct setting of exposure value.
Various models of Zeiss Ikon Contaflex SLR and Contessa cameras have built-in coupled match needle selenium meters. To change the aperture and/or shutter speed, move the red marker hand with the "O" shape loop, such that the "O" is aligned with the selenium meter needle; the shutter speed and aperture is thus selected.
