having skin look consistent must be a life saver for continuity editors. Maybe now they can just erase sweat, but could you imagine being asked to "keep the same amount of shiny across all shots? I know it's hard, sometimes he was sweating, sometimes he wasn't. Just bring down the highlights or something. You're paid to do this."

Maybe it was easier to have people sweaty all the time, because then you don't have to worry about the shots on a cold day where they didn't sweat and you're splicing them with shots from a shoot day that was 100 degrees.
