在这种情况下拍摄者会使用很短的快门时间并调小光圈。
Under those conditions photographers shoot with a fast exposure time and small aperture.
这是因为前一组你用了一半的光圈，而后一组用了一半的快门时间。
This is because you halved the amount of light being let through the aperture opening, but let in twice as much light by keeping the shutter open longer.
在一样的光圈值，我测得天空需要4秒的快门时间，但海面需要40秒。
In the same aperture value, I have found that the sky needs four seconds shutter time, but 40 seconds for the sea level.
因此若要一次拍摄完成且海面要曝光正常的话，需要40秒的快门时间，但这样天空就会过曝。
If I use 40 seconds shutter time to make sure the sea level is exposed normally, the sky will be over exposed.
在这种情况下拍摄者会使用很短的快门时间并调小光圈，这样就不可能拍摄到黑色背景上那些很暗的物体，如星星。
Under those conditions photographers shoot with a fast exposure time and small aperture. That makes it impossible to capture faint objects in a dark background, such as stars.
如果拍另一张照片，用相同时间曝光，但是在行星暗下来时，打开快门，然后冲洗它，行星就是暗的。
If now you take another picture, expose it the same amount of time, but the shutter is open when the star is dim and you develop that picture, the star is dim.
最终，当规定的时间都快耗尽时，那期盼已久的光芒照亮了整个山谷，我迅速的按下尼康相机的快门，它所发出的声音，在整个山谷中不断回响。
Finally, as our time on the island was running out, the longed-for light swept across the valley and the chatter of my Nikon motor drive echoed off the hills.
凭借让照相机快门打开时间延长，通常超过1分钟，就能使用发光二极管、闪光灯，乃至闪光物体绘出光线踪迹。
By having a camera's shutter open for extended periods of time, often well over a minute, trails of light can be drawn with LEDs, flashlights, or even sparklers.
一秒钟内可拍摄610万张照片，快门速度为440万亿分之一秒，在这么短的时间内光也只前进了不到一厘米。
It can take 6.1 million pictures in a single second, at a shutter speed of 440 trillionths of a second. Light itself moves just a fraction of a centimeter in that time.
这个功能让你按下快门后过一段时间再拍照(最多10秒)，它解决了另一个困扰人们多年的问题——没有摄影者的全家福。
This function delays the firing of the shutter (after the button has been pushed) for up to 10 seconds, fixing one of the age old problems in photography: the missing photographer.
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。
Photo Tip: The long exposures required for firework photography mean slow shutter speeds.
照相机快门打开需要的时间越少，物体移动的也就也少。
The less time a camera’s optical eye is open, the less time a subject has to move.
度过由快门速度设置的曝光时间后，后幕帘落下闭合，曝光停止。
After a period determined by the set shutter speed, the rear curtain now drops to close the camera to light and end the exposure.
打开时间的长短就是快门速度。
曾经，我想知道如何关闭我开了45分钟用来拍摄夜空的照相机快门，然后我在Twitter上提问该怎么做，并且在短时间内就有了答案。
Once, I wanted to know how to keep the shutter of my camera open for 45 minutes to photograph the night sky, and I asked Twitter how to do it and got the answer in seconds.
由于快门速度决定了光线照射传感器的时间长短，所以它也是用来控制曝光亮的手段。
Since the shutter speed determines the length of time that light hits the sensor, it will affect the overall exposure of the image by halving or doubling the exposure.
这个窗帘就是快门，当然你能调节它打开的时间。
These curtains are called the shutter, and you can manually set the time you want them to stay open for.
在对的位置等待对的时间对的画面出现，并按下快门，动态止于静态，瞬间之美，纪实幸福。
Waiting for the right images showing up at the right time right position, and press the shutter, dynamic beyond static, instant beauty, happiness recorded.
它采用视频信号控制带有电子快门的C C D摄象机的积分时间以及平面电机自动光圈，实现宽范围全自动调光。
The full automatic light adjustment within a wide range is carried out by the integration time of CCD camera with an electron shutter and planar motor automatic iris controlled by video signal.
那么当你拍摄的时候，快门被打开1秒钟的时间，这1秒钟足够这条鱼从你的取景框前穿越。
When you take the shot, the shutter is open for a full second, enough time for the fish to swim right through the frame.
用激光回波脉冲控制电子快门来操纵摄像机的曝光时间，是抑制背景噪声的一种有效方法。
Steering exposure time of a camera through control electron shutter with laser echo pulse is an effective method for inhibiting background noise.
暴光的时间照相机快门打开并让光线进入所需的或能允许的时间长度。
The length of time required or permitted for a camera shutter to open and admit light.
网点清晰度高，自动控制曝光时间，内置快门保护装置。
The mesh point clarity is high, the automatic control exposure time, in sets at the shutter protective device.
进光时间的长短就通过控制打开快门门帘的时间来实现。
By opening the shutter curtains, the length of time to allow the light to pass through is controlled.
嗯…这对我来说不太好说明，因为我在花时间去思考前我就已经按下快门了！
Maya: Well, that is hard for me to say because I take a picture before I have time to think!
快门延迟是你按下快门键和相机实际抓拍瞬间相隔的时间差。
Shutter lag is the time between your pressing the shutter button and the moment the camera actually snaps.
如果你想创建一个蒙太奇照片从你的旅程只设置相机想要的时间间隔，击中了快门按钮，捕捉高达500万像素的2.5小时的途中的照片。
If you want to create a montage of photos from your journey just set the camera to a desired time interval, hit the shutter button, and capture up to 2.5 hours of 5mp photographs on your way.
如果你想创建一个蒙太奇照片从你的旅程只设置相机想要的时间间隔，击中了快门按钮，捕捉高达500万像素的2.5小时的途中的照片。
