Shutter speed

The following list provides an overview of common photographic uses for standard shutter speeds.

  • 1/8000 s: The fastest speed available in production SLR cameras as of 2009. Used to take sharp photographs of very fast subjects, such as birds or planes, under good lighting conditions, with a ISO number of 1,000 or more and a large aperture lens.[5]
  • 1/4000 s: The fastest speed available in consumer SLR cameras as of 2009. Used to take sharp photographs of fast subjects, such as athletes or vehicles, under good lighting conditions and with an ISO setting of up to 800.[6]
  • 1/2000 s and 1/1000 s: Used to take sharp photographs of moderately fast subjects under normal lighting conditions. .[7]
  • 1/500 s and 1/250 s: Used to take sharp photographs of people in motion in everyday situations. 1/250 s is the fastest speed useful for panning; it also allows for a larger aperture (up to f/11) in motion shots, and hence for a
    narrower
    narrower depth of field.[8]

  • 1/125 s: This speed, and longer ones, are no longer useful for freezing motion. 1/125 s is used to obtain greater depth of field and overall sharpness in landscape photography, and is also often used for panning shots.
  • 1/60 s: Used for panning shots, for images taken under dim lighting conditions, and for available light portraits.[9]
  • 1/30 s: Used for panning subjects moving slower than 30 miles per hour (48 km/h) and for available light photography. Images taken at this and slower speeds normally require a tripod or other camera support to be sharp.[10]
  • 1/15 s and 1/8 s: This and slower speeds are useful for photographs other than panning shots where motion blur is employed for deliberate effect, or for taking sharp photographs of immobile subjects under bad lighting conditions with a tripod-supported camera.[11]
  • 1/4 s, 1/2 s and 1 s: Also mainly used for motion blur effects and/or low-light photography, but only practical with a tripod-supported camera.[12]
  • 1 minute to several hours: Used with a mechanically fixed camera in astrophotography and for certain special effects.[13]

Noted: to take photographs of people in motion use shutter speed 1/250

薪水几时起呢?

什么都起价,就是薪水不会起,如何增加收入呢?我真的很好奇。
