So you have these two parameters, shutter speed and aperture size, both of which do essentially the same thing: control how much light gets in.
现在你已经了解了这两个参数——快门速度和光圈大小，他们从本质上来说有同一个功能：控制进入相机的光线总量。
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。
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。
Night photography is subject to the same set of constraints as daylight photography - namely aperture, shutter speed and light sensitivity - although these are all often pushed to their extremes.
夜间摄影与白天摄影受到同样条件的约束——即光圈，快门速度，感光度——不过它对于这些参数的控制都要达到极致。
You get the same amount of light with a large aperture and a fast shutter speed as you do with a small aperture and a slow shutter speed.
你使用大光圈以及慢速快门所得到的光和你使用小光圈以及高速快门得到的光是一样多的。
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。
You're going to find your spot, set up, select the correct film speed and aperture for the type of storm, open the shutter and wait for the first lightning strike.
你要根据风暴的现状找到自己的最佳位置，设置参数，选择正确的胶片速度和曝光值，打开快门等着第一道闪电的降临。
Taking control of the shutter and aperture isn't easy, but the rewards can be great.
同时控制快门和光圈并不简单，但却绝对值得。
Adjust the shutter speed and aperture.
校准快门速度和光圈。
If you're really feeling bold, try going to manual mode where you control both the shutter and the aperture yourself.
如果你觉得自己足够大胆，那就试试使用手动模式让自己同时控制快门和光圈。
Easy to read and straight-forward, Understanding Exposure offers the basics of aperture, lighting and shutter speed, photography’s basic triumvirate, to beginning and intermediate photographers.
面向初级和中级水平的摄影师，《理解曝光》用简单易懂的文字介绍了光圈、进光量和快门速度这“摄影三角”的基本知识。
As you increase the shutter speed, you'll need to widen the aperture and vice versa.
让你增加快门速度的时候，你可能需要扩大孔径，反之亦然。
When you press the shutter release on the camera, a complex sequence of events occurs, including setting the aperture in the lens, flipping up the mirror of an SLR and a lot more.
实际上，当你按下快门时，一套复杂的程序开启，包括镜头内光圈的设置、一块单镜头反射镜的升起和其他更多的步骤。
Notice that perhaps your camera will select, on its own, a shutter speed of 1/125 with an aperture of F11.
注意相机可能会自动将快门速度设到1/125，光圈设到F11。
Putting the dial on "s" tells your camera "I am deciding the shutter speed, you set the aperture for me."
将指令盘拨到“S ”来告诉你的相机：我设定快门速度，而你来调整光圈。
It is ideal for those who have an understanding of ISO, aperture, shutter speed, white balance and how to change these on your digital SLR or bridge camera.
这门课同样适合那些懂得IS O感光度、光圈、快门速度、白平衡等摄影知识并能用自己的数码单反或桥梁相机设置这些参数的同学。
Even in aperture or shutter priority modes, if you attempt the change one setting, the camera will change the other Settings to compensate.
即使在光圈优先或快门优先模式下，当你调整设定，相机会自动调整另一个设定。
Nevertheless, to avoid incorrect exposure, select a larger or smaller aperture, select a faster or slower shutter speed, or use a flash unit as necessary.
为了避免不正常的曝光，可选择较大或较少的光圈，较快或较慢的快门速度，必要时可用闪光装置。
In fact, using digital cameras provide default mode, phase opportunities from two aspects of the aperture and shutter speed on the adjustment, in order to make the amount of light, doubled.
实际上，使用数码相机提供的预设模式时，相机会从光圈和快门速度两方面进行调节，以使通光量翻倍。
In auto mode and program mode, the camera usually chooses middle-of-the-road aperture and shutter Settings, getting a good exposure but avoiding any extremes-and any creativity as well.
在自动模式和程序模式之下，相机一般会选择一个不大不小的光圈和快门来进行适当的曝光，但这样既不会有任何极端参数，也就更失去了创造的机会。
To take full control of your image, you must use both aperture and shutter speed in conjunction with one another.
要想完全控制你的影像，你必须搭配使用光圈和快门速度。
In the same aperture value, I have found that the sky needs four seconds shutter time, but 40 seconds for the sea level.
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。
