Attention!!!This diffuser is made of pp plastic and is placed on the flash. It will tightly cover the flash to prevent it from accidentally falling out when used. When you want to remove it, you need to use force. It also requires force when put it on. When you can't put it on or you don't know how to put it on, please refer to the sixth product main picture. This bounce diffuser is used to create exposures of even density over the entire surface of film. Use the diffuser by placing it flush against the front of the lens and exposing through it. The light that passes through the diffuser and on to the film will create an even density across the surface of the film. Flash straight on if without our diffuser causes the light to go forward only and creates a harsh shadow behind the subject. The flash with our diffuser installed and tilted at 45 degrees gives a nice soft wrap around of light with a soft shadow behind the subject. This fits cleanly over the head of your existing flash, no need for cumbersome attachments, hooks. Try us and see the difference. - It disperses the light over a wider area for a softer, more balanced and natural effect than you didn't use before. - It helps to reduce hard background shadows and eliminates the annoying red eye effect.Specifications: - Material: High quality pure safe polyethylene (PE) - Color: White - Suitable for speedlite: * Canon 580EX, 580EX II*Nikon SB600/SB800, SB900*Sony F42AM, F58AM * Godox V850II, V860II,TT685,TT600 * Yongnuo YN560, YN560 II, YN560 III, YN560 IV, YN565EX, YN565EX II * And so on.Package: 3 x Bounce Flash Diffuser 1 x YouTin Cleaning Cloth Note: the flash in above picture is not included.
