I know this is quite vague and that some of you might say the setting depends on how much lighting the place has. However, I want to know what "default" settings I can use for shooting pageants, float parades etc where the subject can bypass me quickly (ramp models can walk past me before I get a good shot, etc.
I tried using Manual to shoot but it takes too long to adjust both shutter speed and aperture especially if the lighting can change quickly.
I tried Aperture and Shutter Speed priority but they produce mostly overexposed shots at most times especially when the lighting is quite strong.
Auto mode is out of the question but I tried it and it is more unreliable, often giving me slow shutter speeds.
What can I do about this?
EDIT: I am using a Nikon D7000 with an 80-200 AF lens. Here are sample pictures I took in a dance competition, which is quite the same as the scenario I am asking: subjects are constanty moving and the lighting is quite dynamic and I can't maintain proper exposures
