Hi all, hoping for some help on lighting. My wife and I use an umbrella, a softbox and a Canon 600EXRT flash. Usually it works very well, however we need something stronger. We were out shooting with a family and trying to expose the background and get the family lit up but it wasn't proving easy (and in some cases impossible). I've been looking at Profoto but its a little out of my range at present, especially as we're not charging.

Do you have any recommendations? This is purely for outdoors, we don't use studio or indoor locations at present.

Thanks in advance.
