Recently we've gotten a couple of questions which essentially reduce to How many EV will a softbox knock down off your flash?How many EV will a softbox knock down off your flash? — but that doesn't really have great answers. I know it's not a simple answer (like "add 2 EV and there you go"), but it'd be nice to have some discussion of flash GN and what might be appropriate for example situations. Will a mid-range ~ GN 30 flash ever be useful with a softbox, or is more power basically required when using lighting modifiers?

I'm happy to add a bounty to the above question, but I could also see a new question asking something like "How powerful a flash do I need for use with a softbox in typical situations?"

Which do you think is better?

Flash power and softboxes — add a bounty or add a question?
