Replying to Photography question

hey i got a quick question when it comes to taking quality shots.

scenario: dude is droppin in to hit a huge booter

to maximize the clarity of the photo, do you want to follow him down the inrun with the camera and take the shot when he gets in the air (using high exp. i would assume).

or ,

would you line up the camera to where you want the shot taken, and wait until the rider gets into the frame then take the shot.

i'm kind of an am when it comes to photography, but i want to change that since my dad has a pretty illin' camera

thanks for the help ,
peace.
