After months of thinking about and imagining this shot, I finally got it tonight. And it worked!
Nikon D750, 14-24mm @ 14mm, ISO 200, f/5.6, 1/250 sec. Flash set to 1/2 power in my 24" soft box, camera left at about 7:40 p.m. and sandbagged heavily---the wind almost blew over my stand later in the shoot. And David still has his mad b-ball skillzzzz! ; ) Shot at Holcomb.
