I'm not sure if it's me looking at this on a computer screen in a bright room, but I look at each and every one of those images with a view to determining which one is best for identifying cars and number plates.... say those vehicles on the right that you can see the number plates on. Then I get in sync with the change in the imagine and repeat, low medium high, low medium high so I don't have to move my eyes from a point on the picture to know what frame I'm looking at. To me, I see no difference whatever in that area of the field once I ignore the effect of some lights being on and turning off and vice versa which accompany the change in camera setting. What I'm trying to say is.... whatever the setting is WDR on or off, low/centre weighted/full frame, or high/medium/low contrast.... makes no difference whatever with id of cars or plates.
