    后帘同步拍摄有虚影是什么情况?
    2017/9/21 16:41:54

    济南艺考摄影培训之前帘同步指的是当前帘打开,闪光灯就开始照亮被摄物体,然后相机进行曝光。后帘同步指的是当前帘打开,闪光灯先不闪光,而是等到后帘关闭前的一瞬间,闪光灯才闪光并完成曝光。

    The front curtain synchronization means that the current curtain is turned on, the flash begins to illuminate the subject, and then the camera is exposed. The rear curtain synchronization means that the current curtain opens, the flash does not flash first, but when the rear curtain closes, the flash flashes and completes the exposure.

    当拍摄静止物体时,画面中的主体不存在运动轨迹,所以这两种闪光方式的作用是一样的,都是保证主体和背景都曝光正确。

    When a stationary object is photographed, the body of the picture does not have a motion track, so the two flash modes act the same, ensuring that both the subject and the background are exposed properly.

    但是在用低速快门在傍晚、夜间或室内拍摄动体时,如果用前帘同步,当闪光灯闪光后,由于被摄体还在移动,所以会在曝光位置前方留下被摄体移动的虚影。

    But in the low speed shutter in the evening, night or indoor shooting moving body, if the pre curtain sync, when the flash after flash, because the subject was still moving, so the shadow in front of the exposure position left the subject moving.

    但如果用后帘同步拍摄,虽然仍然会拍下被摄体移动的虚影,不过闪光灯是在后帘关闭之前才闪光,所以能把被摄体拍得很清楚。

    But if you use the rear curtain to shoot simultaneously, the camera will still be photographed, but the flash will flash before the curtain closes, so you can photograph the subject clearly.

    遮光罩是摄影的必备物品。要想拍出美丽的照片,最重要的就是只让参与成像的光线进入镜头。

    Lens hood is essential for photography. The most important thing to do is to let the light involved in the image go into the lens.

    使用遮光罩可以遮挡各个方向射向镜头的干扰光线,仅仅保留来自拍摄对象方向的光线。在拍摄过程中如果有干扰光线进入镜头,就会在镜头内引起杂乱的内反射,造成照片对比度低下、画面不清晰等情况。

    The use of the hood can block the direction of the lens to interfere with the light, only to retain the direction of light from the object. In the shooting process, if there is interference, light into the lens, it will cause confusion in the lens of internal reflection, resulting in low contrast, the picture is not clear and so on.

    顺便一提,有些镜头的遮光罩上有小窗。在使用能抑制拍摄主体表面反射的PL(偏振)滤镜时,需要通过旋转PL(偏振)滤镜来控制画面效果。

    By the way, there are some small window lens hood. When using the PL (polarizing) filter that suppresses the reflection of the subject's surface, you need to rotate the PL (polarizing) filter to control the picture.
