People usually look better with a slightly warmer WB setting, as the one in 2nd pic. (There is no way of 'none', btw.) It's not about preference, it's about what looks appropriate since it's reportage / event photography here. Unless you want to sell prints to the participants...
ya i think i can spot the difference, though it's quite small.
I looked at the walls and door, like sama-sama.
The red shirt is of a different 'intensity' in both photos.
But the difference is very subtle, to be honest.
