So dramatic. Unlike you i don't feel like i am being killed. I always use single point focus and i know to under expose or over expose based on light, its not that hard. Tech is good of course, thats why i love my 5dm3.
No, it is not that hard and I do that all the time. 1st shot (/w bounced flash) with an estimated expo comp based on experience, look at the histogram and chimp it, adjust the expo comp if necessary, and than reshoot... Well, sometimes the chance is missed and u cannot shoot again during a wedding... Well, I am sure one would say we could Lightroom the exposure back but I prefer to get the correct exposure to minimize the amount of post-work. There is an additional benefit too. I can just use the jpgs directly out of the camera/DPP, which has better color than Lightroom or ACR after raw processing, IMHO.
