well, i don't know much..
but i can tell you that, 420ex (i used it before) produces the effect quite naturally... as in no hard light effect, on my 300d. but the in built flash of the camera sucks..
so i wonder that makes a difference...
anyone care to share?

u take the guide number divide by the distance,that will give u ur aperture.stop down one stop if u just need a fill.
GN is usually given in ISO100,for ISO200 x1.4 ISO400 x 2
ie: GN40 / 8ft distance = 5 so ur aperture is F5.6 for fill is F8

ya, sounds straight forward

The guide number rating is the maximum output power of the flash.
