Answers.Text: You didn't say anything about shooting at night.  If you've got the ISO (sometimes called gain) cranked up, the aperture as open as it can be, and the shutter speed cranked up to where you don't see motion blur, there are only 2 ways to get a brighter exposure: 1. Add more lights. 2. Get a better camera.

Answers.Text: Thanks for the info on ISO(called gain). I guess add more lights are better option.

  @ Jason ppf is pixel per foot. It's a minimum requirement of object pixels that required.

  Shutter speed and motion blur are inversely proportional. The higher the shutter speed, the less amount of motion blur, so crank up the shutter speed as high as it will go. If the exposure comes out too dark, add more lights.
