I finally have my first sparkler exit coming up tomorrow evening. I'm going to be working alone by this time of the night so I need to keep my set up pretty simple; probably just an on-camera 580.
So my question is about balancing the power of the flash with the ambient. I obviously don't want to blow away the darkness or the sparkle of the sparklers, but I'm guessing I will need to add light to the couple. So thoughts on the most reliable approach?
I'd like to get a few shots; one with the couple futher away shot wider and another with them closer. I'm thinking the flash will be in ETTL and maybe I will have the zoom on it set manually to something more narrow than my focal length, but I'm open to ideas and insights.
Thanks.
