１ ３在使用三角光之前 ,必须用测光表量好每盏灯的强度达到一样 ,再测好被灯照射的主体的光圈值就可以了。在拍摄的过程中 ,距离缩短 ,相应光圈缩小 ,距离增大 ,开大光圈 ,某盏灯改变距离 ,就形成光比的变化。这样的方法 ,拍摄时灯光出错的机会就很少 ,也不必要记住哪盏灯光强 1 3 Before using Triangular Light, you must use a light meter to measure the intensity of each light to achieve the same, and then measure the light intensity of the subject illuminated by the light. In the process of shooting, the distance is shortened, the corresponding aperture is reduced, the distance increases, open a large aperture, a lamp to change the distance, the formation of light than the change. In this way, there is very little chance of lighting errors when shooting and it is not necessary to remember which lights are strong
