Ok, I got the camera and am trying to set this up, I am reading page 102, and got to the correct screen, but I am unable to set the points on the -1,0,1. i can scroll over to them, but how do i select those points?
You should be able to scroll the wheel when on that line, and it should adjust the 'spread' of the points. You may have to click before it will let you scroll.
