Flashes produce a harsh light, even when you use it with the little plastic built-in diffusers / reflector of the flash. To work close to a subject, you may need to soften the light. Flash diffusers are here to help you. It is to be attached to the flash head by an elastic cord and therefore fits almost all dimensions of the flash. It is also extremely lightweight. Flash diffusers not only diffuse light, they spread the light too. The coverage area of the diffuser is higher than other broadcasters. It could diffuse flash light to a much wider angle. It also reduces the maximum working distance between the flash and the subject while keeping the normal color temperature.
