六、光圈、快门、感光度的合理运用摄影人都了解光圈和快门的关系其实就是为了得到正确曝光的一种对应关系。通常来说光圈的主要作用是控制景深和曝光量,快门的主要作用是控制曝光量和使动体影像“凝固”。舞台摄影也不例外,当我们需要小景深、主体突出背景虚化的时候,可以采用光圈优先拍摄模式并增大光圈。反之可以缩小光圈,取得大的景深。当我们需要使动体影像“凝固”的时候,可以采用快门优先拍摄模式提高快门速度。反之可以降低快门速度,从而得到一个虚化的具有动感的影像。舞台
Sixth, aperture, shutter, the rational use of sensitivity Photographic people understand the relationship between aperture and shutter is actually a correct correspondence to get the exposure. Generally speaking, the main function of the aperture is to control the depth of field and the amount of exposure. The main function of the shutter is to control the amount of exposure and to make the moving image “frozen ”. Stage photography is no exception, when we need a small depth of field, the main highlight of the background blur, you can use aperture-priority shooting mode and increase the aperture. Conversely, you can reduce the aperture, get a large depth of field. When we need to move the body image “solidified ”, shutter-priority shooting mode can be used to improve shutter speed. On the contrary can reduce the shutter speed, so as to get a blur with dynamic images. stage
