When taking portraits etc which would you says works best for you in terms of light diffusion? A flash softbox (Are those inflatable types any good?). A reflector like the Flipit (I have one but it's problematic if you shoot portrait cuasing side shadow and requires an extra swing extension which I do not currently have). Or something like one of those Gary Fong lightsphere's? (What's the difference between branded vs unbranded Ebay cheapo lookalikes?)
