I do a lot of event photography and award ceremonies. For awards the standard formula in the Military is what we call the "Grip and Grin" shot. I will take 2-3 shots in quick succession to account for blinking and looking in the wrong direction which always happens. There is almost never enough time for more shots on any single person and the 3-Star waits for no one!
I very rarely use Live mode on my camera but a certain percentage of these shots no matter how hard I try end up with an out of focus shot. We can easily run through 20 people with the same exposure and I will typically get a 2 or so which are a bit OOF. I can't always prevent people blinking or looking away but I'd surely like to increase my keeper rate. Using Live View with face recognition, although certainly slower just wondering if this will decrease or increase on the percentage of keepers. There is certainly not do-overs in this type of photography so its critical that I get the focus correct at the very least.
The Grip and Grin... Framing not great but in focus.
