I'm in the process of shopping for a hot shoe flash to use on my camera. But, I'm also considering buying an umbrella and stand so I can use it as a portable portrait kit. Does anyone have experience doing this? Can you comment on power? There's no direct relationship between Guide Numbers and Watt Seconds, so I'm not sure what GN would be good for this type of application.
If any of you have done this, what was the GN of your flash, and how well did it work?
Thanks,
Paul
