I have a wedding coming up in May and want to set up a photo booth at the reception. Just wondering if a 43 inch umbrella (using it as a bounce rather than shoot thru) will be large enough to get good coverage for maybe up to 5 people using an SB600? Of course it will be a fairly confined area so I should have somebouncing off other surfaces as well. Not something I will use on a regular basis so I don't want to go any bigger (and spend more cash) if I don't need to.
Any feedback appreciated.
