    什么情况下可以使用快门优先模式?

    一.人像拍摄

    One. Portrait shooting

    1.要用到长焦,3――4倍的长焦非常适合拍人像,广角端会使得人像有些变形,不好看,超过4倍甚至更长焦会使得人脸过于扁平,不够生动。

    1., use the long focus, 3 - 4 times long focal length, very suitable for shooting portrait, wide angle end will make portrait some deformation, not good-looking, more than 4 times or even longer, focus will make the face is too flat, not vivid enough.

    2.光圈优先,选择大光圈,大光圈可以使得快门变快,减少晃动,并且使得背景尽可能的虚化。最好选择点测光,对人脸点测光,并使用曝光锁定。因为其他测光方式容易受到衣服颜色的影响,使得人脸曝光不正常。

    2. aperture priority, select large aperture, large aperture can make the shutter faster, reduce sloshing, and make the background as virtual as possible. It is best to select spot metering, spot metering, and exposure locking. Because other photometry are easily affected by the color of the clothes, the exposure of the human face is abnormal.

    3.构图。人像最好占到1/3-1/2,并且脸部在上方1/3处(从下看是处)。这样拍出的人像片就会生动,有视觉的冲击力,让人看着好看。

    3. composition. The portrait is preferably 1/3-1/2, and the face is above 1/3 (from below). This shot will be vivid portrait, visual impact, so that people look good.

    4.光圈优先就是手动定义光圈的大小,相机会根据这个光圈值确定快门速度。由于光圈的大小直接影响着景深,因此在平常的拍摄中此模式使用最为广泛。在拍摄人像时,我一般采用大光圈长焦距而达到虚化背景获取较浅景深的作用,这样可以突出主体。

    The 4. aperture priority is to manually define the size of the aperture, and the camera will determine the shutter speed based on this aperture. Since the aperture size directly affects the depth of field, this pattern is most widely used in normal shooting. When shooting a portrait, I usually use the long focus of the large optical circle to achieve the virtual background, so as to gain a deeper depth of field, so that the main body can be highlighted.

    5.同时较大的光圈,也能得到较快的快门值,从而提高手持拍摄的稳定。在拍摄风景这一类的照片时,我往往采用较小的光圈,这样景深的范围比较广,可以使远处和近处的景物都清晰,同样这一点在拍摄夜景时也适用。

    5. larger aperture at the same time can also get faster shutter value, so as to improve the stability of handheld shooting. When I take pictures of landscapes, I tend to use smaller apertures so that the depth of field is wide enough to make the distance and the near scene clear, as well as the night scene.

    与光圈优先相反,快门优先是在手动定义快门的情况下通过相机测光而获取光圈值。快门优先多用于拍摄运动的物体上,特别是在体育运动拍摄中最常用。很多朋友在拍摄运动物体时发现,往往拍摄出来的主体是模糊的,这多半就是因为快门的速度不够快。在这种情况下你可以使用快门优先模式,大概确定一个快门值,然后进行拍摄。

    Contrary to aperture priority, the shutter priority is obtained by camera metering when the shutter is manually defined. Shutter priority is used mostly for shooting objects, especially in sports shooting. A lot of friends when shooting moving objects found that often shooting out of the main body is fuzzy, this is mostly because the shutter speed is not fast enough. In this case, you can use the shutter priority mode to determine a shutter value and then shoot.

    并且物体的运行一般都是有规律的,那么快门的数值也可以大概估计,例如拍摄行人,快门速度只需要1/125秒就差不多了,而拍摄下落的水滴则需要1/1000秒。

    And the operation objects are generally regular, then the shutter value can also be estimated, such as shooting pedestrians, shutter speed is only 1/125 seconds to almost the same, while filming the whereabouts of the drop is needed 1/1000 seconds.
