If one is maliciously might call "shower cap" this diffuser also. Nevertheless, this thing has proved very useful. I've done some portrait photos and have to say this is the effect clearly visible. When flash without diffuser has always somewhere on the complexion, brighter spots, as even with highly reflective surfaces. With the diffuser, these effects are clearly reduced, the light is softer and more scattered. The skin tones come out much more natural. For the little money that these "shower cap" cost that is a "Top" for me.
