Shutter speeds are adjustable between 60 and 1/4000 seconds.
拍摄速度则可在60至1/4000秒间可调。
High shutter speeds enable moving objects to be clearly photographed.
高的快门速度能使移动的物体被清晰地捕捉下来。
Photo Tip: The long exposures required for firework photography mean slow shutter speeds.
照片说明：拍摄焰火照片需要长时间的曝光，这意味着要降低快门速度。
Just like a lens has a range of apertures, your camera has a range of shutter speeds.
就像镜头有一个光圈范围，你的相机也有一个快门速度的范围。
But because star trail images need very long shutter speeds they take a lot of patience.
拍摄星星移动的照片需要很长的快分时间，所以必须得有耐性。
Now in part two we're going straight to manual mode to learn about aperture sizes and shutter speeds. So let's do this thing.
那么现在，进入了第二部分的我们将要开始学习光圈大小以及快门速度，让我们这就开始吧。
At very long shutter speeds, like 30 seconds, you will almost never get sharp photos hand-held, regardless of having VR.
在很慢的快门下，如30秒门，你几乎不可能在手持状态下拍到清楚地照片，不管你有没有防抖功能。
A very rare camera in 100% original condition. Slow shutter speeds sticky, nice wear only one minor dent at the top plate.
这是100%原装罕见机子，快门速度偏慢，除了一处小磕痕以外，外壳完好。
Photo Tip: For everyday pictures such as portraits and views, use shutter speeds of 1/60 of a second to 1/250 of a second.
拍照小技巧：拍摄一些日常的照片时，例如肖像照或者其他照片，应使用。
This arrangement allows for much shorter shutter speeds than could be achieved by moving a single door. The animation below explains this more clearly.
这种设置使得相机获得了更短的快门速度。
All of this is a lot to remember. Juggling f-stops, shutter speeds, and ISO values in your head while trying to compose a shot can be tough, especially for beginners.
太多参数需要记住，尤其对于初学者来说，相反的f值，快门速度，以及IS O值，在准备拍摄一张照片的时候这些参数实在太过复杂。
You'll usually need to work with higher shutter speeds if normal sync at your chosen aperture and ISO will result in overexposure of the ambient lighted portions of the image.
如果普通同步速度配合你选用的光圈和ISO会导致环境光过曝，那你就需要更快的快门速度。
Photograph it at different shutter speeds, from slow to fast (adjust your aperture to maintain correct exposure), and see what affect it has on the appearance of the subject in the photo.
尝试用不同快门速度拍摄，由低到高(调整光圈以获得正确曝光)，注意观察它为你的拍摄带来了何种影响。
Just like with f-stops, there is a mathematical relationship between different shutter speeds-each shutter speed stays open half as long as the one above it, or twice as long the one below it.
就和f值一样，这一组数字也是一个数列关系，每一档快门速度都是比上一档快一倍的时间，或者是慢一半的时间。
Now, you can go ahead and shoot at F4 with shutter speeds up to the Max the camera has available. And you still achieve that precious look that we all want; a portrait with a blurred background.
现在你可以在F4光圈下用任何快门速度甚至相机最快的快门速度拍摄，取得你想要的拍摄效果：背景模糊的人物像。
In stills photography the term HDR is used to describe a technique for displaying greater dynamic range in a single image by combining several exposures photographed at different shutter speeds.
在平面摄影中，HDR代表通过不同快门速度多次曝光在单一画面中呈现更高动态范围的拍摄和修片技法。
Kodak's system is reasonably effective , producing sharp images most of the time at full zoom anda shutter speed of 1/25th of a second, although slower speeds defeated it.
柯达的系统令人印象深刻，在1/25秒的快门速度时，大多数时候在各个焦段都能拍出锐利的照片，尽管快门再慢就不行了。
Kodak's system is reasonably effective , producing sharp images most of the time at full zoom anda shutter speed of 1/25th of a second, although slower speeds defeated it.
