BOOSTY 3 Color Pop Up Hot-Shoe Flash Diffuser Set for DSLR Cameras FLASH Diffuser  (Multicolor)

The diffuser is used to create exposures of even density over the entire surface of film It helps to reduce hard background shadows and eliminates the annoying red eye effect Flash straight on if without our diffuser causes the light to go forward only and creates a harsh shadow behind the subject 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 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
