Falcon Eyes Mini-Reflector FGA-SR178W

This mini-reflector allows the contrast of lights to be more harmonious, it helps decreasing the unnecessary shadows and direct light. It is good for highlighting the subject. 
 

The effect is especially obvious in close-up photography. 
 

It is better to shoot under off-camera mode since the flash can be illuminated from desirable position and got the best effect as a result.
