The flash is aimed at the ceiling, wall or flash reflector, which disperses and softens the light, and bounces it back at the subject.
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。
You can even Angle your flash up and behind you to fill a small to normal-size room up with beautiful light. Spin it around and up at about 45 degrees to hit the wall and ceiling behind you.
你还可以使闪光灯角度向上或向你身后，将闪光灯旋转45度朝向墙壁和天花板打光，让美丽的光线充满整间房子。
But what if you don't have a wall or other surface to bounce your flash off of?
但是如果没有墙或天花板可用呢？
Along the new coastline I can see construction crews building a sea wall. There are cement-pumping trucks, cranes, large steel pipes, and the flash of welding torches.
沿着新的海岸线，我看到施工队伍正在建设海堤。那里有无数的水泥泵车、起重机、大型钢管和闪着焊花的焊枪。
If you look at the direction of the light on her face, you'll immediately see where I bounced the flash from - the wall to my above right.
如果你注意到了新娘脸部光线的方向你就能立即看出我将闪灯打到了哪个方向—我右上方的墙上。
If you bounce the flash off a wall to the side of you, or behind you, then the source of light relative to the subject, is much larger than if you had shot with the flash straight on.
如果你把闪光灯打到你旁边或身后的墙上，相对于拍摄主体来说，此时的光源面积要比直接将闪灯打到主体上要大的多。
For this photo I once again had my flash bouncing over my left shoulder, into the wall and ceiling behind me. By bouncing flash this way, I was trying to emulate soft light from a large window.
这张照片我也是将闪灯打到我左肩后方的墙和天花板上。这么做我是想模拟从一扇大窗户里进来的柔和的光线。
This might include moving them a little further from an open window (just outside the direct rays), or aiming your flash at a nearby wall or ceiling.

In the pre-forming die, a resistance wall was adopted to build the flash groove and a convex web structure was used to connect the great varying cross-sections.
在该预锻模中，采用阻力墙形式构造飞边槽，采用凸形连皮结构连接多个大变截面。
