The camera still works great in aperture priority mode, though, so exposures are accurate.
该相机还工作在光圈优先模式的伟大，虽然如此，风险是准确的。
Since the amount of light reaching the camera is dependent on the aperture, the overall exposure is altered by changes in aperture.
由于光圈控制着进入相机的光线总量，也就是说曝光强弱可以由光圈来控制。
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。

带橡胶芯的金属丝导电密封条能够通过导电胶粘结(金属丝的接触点能够穿透薄膜)固定在沟槽或缝隙内。
Since aperture is the main event in aperture priority mode, you may not need to press the aperture button; simply rotate the command dial and look for the changing Numbers in the LCD status screen.
就光圈优先模式来说，光圈是最主要的参数，所以你并不需要再按光圈按钮，直接转动指令盘并且在LCD上查看数值变化即可。
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。
When viewing extended objects, the apparent brightness seen in the eyepiece is a function only of aperture and magnification, it is not related to focal ratio.
当观察扩展光源时，目镜中所看到的亮度只跟孔径和放大率有关，它跟焦比并没有关系。
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。
In general, all you really need is one that is around F1.8 as that aperture is wide enough for most uses and you may even find yourself closing that up at times.
基本上，光圈在1.8左右的镜头已经足够大多数人使用了，并且时常你还要把光圈调小了使用。
The simplest way to do this is to choose a small Aperture setting (a large number) as the smaller your aperture the greater the depth of field in your shots.
最简单的办法是选用最小的光圈设定（镜头上显示的最大的数字），光圈越小，你所获得照片的景深就会越大。
This is not the star's disk you are seeing but the effect of having a circular aperture in your telescope and due to the nature of light.
这不是星星自身的光环，而是由于望远镜的圆形孔径光阑以及光的物理特性造成的。
If you know the focal ratio but not the focal length, you can calculate it: focal length is the aperture (in mm) times the focal ratio.
如果你不知道焦距，只知道焦比(focalratio)，你可以通过这样计算的得到焦距：孔径(单位是mm)乘以焦比就是焦距。
You set the aperture, which dictates how much light comes into the camera-do you want a nice, shallow depth-of-the-field, or everything in focus?
你设置光圈(用于指定有多少光进入照相机镜头)——你想照一幅漂亮、浅景深或广角的照片吗？
Portrait mode chooses a large aperture (a small 'f' number) which will make the depth of field (the amount of your shot in focus) smaller.
人像模式用一个大光圈(f值小)，而让景深(清晰对焦的那部分)变小。
The f-stop, otherwise known as the aperture, determines your depth of field (the area in focus) and how much light can pass through the lens to reach the sensor.
f制光圈(或称光圈)决定相机的景深(对焦区域)以及有多少光能通过镜头到达传感器。
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.
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。
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。
And when the real data trickle in from something as big as an 18-meter aperture space telescope, astrobiologists will be befuddled interpreting it. They may never reach a consensus.
当真正的数据来自于某些像18米孔径的空间望远镜时，天体生物学家将无从解释，而且永远也不能达成共识。
We saw light through a small aperture in the wall.
我们透过墙上的小孔看到了亮光。
That price obviously puts large aperture scintillometers out of the reach of the average farmer in, say, India.
大眼睛闪烁仪的这个价位对于诸如在印度的普通农民来说，实在是太昂贵了。
The very gravity distortion also effects the space-time continuum in the area, and creates a dimensional aperture field very similar to what occurs in the poles.
引力的极度扭曲也能对此区域的空间-时间的连续性产生影响，并产生一个维度裂缝，这种现象非常类似于在两极出现的现象。
The main lens is fixed in place; there is no auto-focus, auto-aperture, or other gubbins.
主要镜头是固定的，没有自动对焦和自动光圈以及其他小配件。
If Keck can see back in time, imagine what the biggest telescope in the world, the Great Canary telescope, can pick up with its chart-topping aperture.
如果说凯克能回溯时光，世界上最大的望远镜——大加纳利望远镜拥有最为强大的物镜，又具有什么样的能力呢？
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。
This results in the forward motion of the aperture.
这一结果在向前运动的光圈。
This results in the forward motion of the aperture.
这一结果在向前运动的光圈。
