The Bouncer is made properly and is simply placed in front of the flash. He will scatter the hard flash, thus reducing the shadowing. This effect is also theoretically undisputed. However, the Speedlite 270 EX II is relatively faint, so you should at any sparks light actually be grateful that you get. Add to this that the shadows are the stronger, the stronger the flash. In this relatively weak flashlight so you mitigates anyway a little pronounced effect.
