反射闪光指光线从天花板、墙壁或其他表面反射回来以柔化照射在主体上的光线。因为反光表面的色彩会影响光线的颜色,所以白色或浅色的表面是最佳的选择。与直接闪光相比,反射光线的亮度也会降低,因此需要调整光圈或ISO感光度设置。
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.
