1/400 sec at f/5.6, ISO 200 – Fill Flash via High Speed Sync
After doing my Canon 600EX-RT Wireless Real World Test article several readers have asked me how they perform when being shot wirelessly on sunny days, and a couple people asked about their wireless high speed sync performance for use as a fill flash.
I tried to answer all these questions in one shot above where the sun was setting. I shot directly into the sun with my camera set to 1/400 sec and used an external 600EX-RT on an umbrella as a fill flash via high speed sync. I got the desired lens flare and warm sunset look, but I also got the fill light to keep my subject from being backlit. I also got catch lights in her eyes.
There’s minimal processing on this shot taken from a Canon 5D Mark III that has been processed mostly in Photoshop CS6 Beta and Lightroom 4 from the original RAW which was processed in DPP. It’s not a portfolio shot, but it does prove the point that I can indeed get the fill flash using high speed sync (required at anything over 1/200 sec on this camera). I can also get more ambient light on the background if I want it by simply raising the ISO which I did not want to do for the this shot.
The 600EX-RT’s fired every time in the 58 times I tested this scenario, so they had no trouble with the sun (which should be true of any radio triggered flashes).
I hope that helps those who were interested in this question!
If you have a question for me, feel free to send me a mail with the subject Ask Ron. I can’t promise I’ll answer every question, but you may see your response on the next Ask Ron!
Best wishes,
