During Amy & Brock’s elopement photos this past weekend I was using three of the new Canon 600EX-RT speedlights, one on-camera and two off-camera, with my 5D Mark III. After continuously shooting with the speedlights firing at full power (the shoot took place during the middle of a very sunny day), I noticed there were some instances when the flash didn’t go off. However, since I’d already metered for the background light, those instances weren’t a total loss. I was mostly using the extra light from the flashes to really make the couple pop, and to separate them a bit from the background. I really like the image below but the flashes didn’t fire; they’d overheated. Since I was shooting everything in Manual Mode I knew my background would match all the previous images; I simply needed to do a bit of work in Adobe Lightroom and was able to deliver this final result to Amy & Brock.
