半按快门本是数码相机最基本的操作功能,当我们慢慢地往下按相机快门,按到大约一半时手指会明显地有一种阻滞感觉,这时快门并没有释放,也就是说还没有拍照,这就叫半按快门,只有将快门按到底听到“咔嗒”一声响后,拍照才算完成。
如果你半按快门,你的相机就会解读目前你所设定状态下的曝光情况。
If you half click the shutter, your camera will read the light and place a line where it believes your exposure will be if you take the picture with your current Settings.
首先,将拍摄对象居中,然后将快门按钮按下一半。
First, center the subject and press and hold the shutter button halfway down.
快门按至一半位置,液晶屏和取景器会出现显示,如完全按下,快门释放。
If it is pressed halfway, the LCD panel and the viewfinder display operate. If it is pressed fully, the shutter is released.
