Beauty Dish Shots (below)
My unscientific conclusion leaves the Profoto Acute 600R coming out on top. The light is more controllable, and the twin 600EX-RTs can’t produce the amount of power I needed to overexpose the sun. I purposely tried shooting directly into the sun to test out what it would take to get a proper portrait exposure, and the umbrella setup was harder to get dialed in. I could get a 1/3200 sync at f/2.8, but there still wasn’t enough flash power to cut through the sun.
