you mention indoors, i was thinking more outdoors where i cant bounce the flash and want the flash as fill light. Would these cups still work at removing the harsh flash? or lowering the power of the flash make the same effect?
And where u using the business card as a bounce card? did it work at all? even if it looked stupid?
thanks for the help.
Diffusion domes aren't directly responsible for making light softer (this is dictated to by the size of your 'light', hence why studios use umbrellas), rather, they scatter it so it can then be bounced off walls, ceilings and the likes making it appear like you have one big light source. In short, they work best when you have bounce available.
The 'business card', simply is kinda an extension of the diffusion dome idea in that the flash throws light up which can be bounced etc, but the card directs it forward a little more-great for portraits etc.
For outdoors, all the dome is doing is robbing you of power as it's throwing your light out in all different directions. In these intances, where you can't bounce, you want something like this to effectively increase your light source.
My 'business card' soon grew to something similar in size but certain family members graffitied it at Christmas...
I'd also try reduing your flash power and balance more with ambient light as generally, a balanced (bare) fill flash is all that you need to illuminate a subject whilst retaining some background definition. If your flash has a 'wide angle diffuser' (the thing that folds out and looks like a bike reflector), use that as that will direct light out a little more.
You can also get those big tupperware thingos (Gary Fong domes I think they're called) which are kinda an 'in between' as they not only diffuse light up, but they throw it out more than a standard diffusion dome and they work pretty well outdoors (so I've heard...I've never used one and they look pretty darn funny!)
There are much more knowledgable members here so I'm hoping someone else puts in their $0.02 worth also...
Hope that helps mate.
