I initially thought that you've used (external) flash gear for a, so called, 'fill-in flash', Jeff. But on closer look I suppose that your very fine capture was lighted in the natural way. If so, an amazing image in spite of the difficult lighting conditions there!

I experimented with a flash for a while but I never liked the results. It has been years since I've used it. All my pictures are natural lighting with tweaking in Lightroom.
