    低ISO设置会导致快门速度过慢

    如果从画质第一的角度考虑,ISO应当设置在最低挡(ISO 50~ISO200,由相机自身的技术规格决定)。但是在实际拍摄中,上海摄影培训学校遇到了很多问题都非如此简单,因此在必要时采用高ISO设定是唯一的手段。
    If from the point of view of the quality first, the ISO should be set at the lowest gear (ISO 50~ISO200, determined by the technical specifications of the camera itself). However, in the actual shooting, the Shanghai photography training school has encountered many problems that are not so simple, so the high ISO setting is the only means when necessary.
    当现场光线不足时,低ISO设置会导致快门速度过慢,手持拍摄无法保证照片的清晰度——没有清晰度,画质就无从谈起。
    When the scene light is insufficient, the low ISO setting causes the shutter speed to be too slow, the hand-held photography cannot guarantee the picture clarity - - without the clarity, the picture quality has no way to speak.
    当然,我们可以使用三脚架固定相机进行拍摄。对于喜爱风光摄影题材的朋友,三脚架是必备的辅助器材。
    Of course, we can use three tripod fixed cameras to shoot. For those who enjoy the scenery and photography, friends, three feet are necessary auxiliary equipment.
    尽管如此,有时可能三脚架不在身边,或是拍摄的场地不允许使用三脚架,此时就需要使用高ISO设定。
    Even so, sometimes three tripods are not around, or shooting sites are not allowed to use three tripods, which requires the use of high ISO settings.
    如果我们要拍摄的主体处于运动状态,那么由于曝光时间较长,即使用上三脚架也无法保证其清晰,此时同样需要设定较高的ISO来解决这个问题。
    If we want to shoot the main body in motion, then because the exposure time is longer, that is, the use of three tripods can not guarantee its clarity, at this time also need to set a higher ISO to solve this problem.
    由于ISO的提高会不可避免地导致噪点增加、画质下降,因此我们需要找到一个恰当的折中点——在设置能够保证主体清晰的足够高的快门速度的前提下,最低ISO值将是最佳的选择。
    Due to the increase of ISO will inevitably lead to increased noise, quality degradation, so we need to find an appropriate compromise -- in the premise of ensuring the clear body can set high enough shutter speed, the lowest ISO value will be the best choice.
