My first question is what would be the difference between a dedicated flash\nsuch as a Canon 550EX/580EX and studio strobes? For example, would you get\njust as good results using a Canon 580EX with an umbrella/softbox as you\nwould with a studio strobe with the same umbrella/softbox? (Obviously\nunless you were shooting a big subject, with a massive softbox/umbrella).\n\nMy second question is why use flashes/studio strobes at all? Why not use\nvideo lighting which emit a permanent light source? Especially with\ndigital, whereby you can adapt the white balance 'on the fly'?
