因为闪光必须在反射若干次后不被吸收或者变得太弱，所以不是所有的光都可以用，必须是激光。
Because the flash must survive multiple reflections without being absorbed or becoming too weak, not just any light can be used. It must be a laser.
依此思路推测，它有点像“铱闪光”，它是由太阳光反射到铱卫星上所产生。
In this way it would act like an 'iridium flare.' The flares are created by sunlight reflecting off iridium satellites.
闪光会被门反射，接着会打在那个人以及人后面的墙上。
Light from the flash would be reflected off the door and onto both the person and the walls behind that person.
要是您有机会接触下那种可以从天花板或者墙壁反射回来的闪光灯，效果则会明显得多。
If you have access to a flash that can bounce off the ceiling or walls, that could work much better.
该触屏电脑的工作原理是——电脑内部发出闪光穿透屏幕，遇到物体时再反射回电脑屏幕后的传感器。
The screen works by shining light upwards through the screen, which bounces back to a layer of sensors behind the screen.
闪光时对准天花板，墙面或反光板，使得光线分散和柔化，并反射到被摄物上。
The flash is aimed at the ceiling, wall or flash reflector, which disperses and softens the light, and bounces it back at the subject.
最后我是用5合1反光板的白色反光板，将部分闪光灯的光反射到Sharon的帽子上，使她的头像照看起来更漂亮。
Finally, the white side of the 5-on-1 reflector set bounced light from the strobe back up under her hat and added a little bit of a beauty look to the headshot below.
反光还会造成景物曝光不足。因此拍摄时，请与光亮背景保持一定角度，以减少闪光的反射影响。收藏。
The reflected glare may also cause underexposure. Take pictures at an Angle to shiny surfaces to minimize flash reflections.
猫眼里面有一层特殊的膜，能反射光线，使猫眼在黑暗中闪光。
Inside a cat's eye is a special membrane that reflects light, making the eye shine in the dark.
最重要的是，一个填充光很容易创造：不是一个简单的闪光或反射器指向通常是足够了。
Best of all, a fill light is easy to create: either a simple on-camera flash or a reflector is often sufficient.
采用抛物面反射器，围绕白炽灯旋转，每分钟60次闪光，闪光全面。
It features a parabolic reflector that rotates around an incandescent lamp, providing 60 flashes per minute in all directions.
闪光灯输出功率的计算仍然是根据预闪反射光的中心加权测量结果。
The flash power calculation is also based on centre-weighted metering of the light reflected by the pre-flash.
闪光灯输出功率的计算仍然是根据预闪反射光的中心加权测量结果。
