I shoot sporting events and sell prints (on and off site). I shoot all sporting events in JPEG.
I am mostly interested in photographers that take hundreds, or more likely, thousands of shots a day (print sellers).
Not so much the casual shooters, or the newspapers guys who only need to grab a handful of workable shots.
If you shoot some of both, I guess you can just vote for whichever you use the most.
What percentage of (pro) sports shooters use JPEG and what percentage use RAW?
