Hi Guys I need some advice whether or not to buy a diffuser for my flash gun. I take quite a few indoor portrait and full body shots for personal and semi-pro use... question is... do they make any difference? I have found by 'bouncing' the flash off the ceiling/walls I am getting quite a bit of solid light and still creating shadows. I have tried using a make shift reflector but still am unhappy. Any thoughts and advice would be very much appreciated Thanks!
