  Correcting exposure variation in Time Lapse

  Posted by John Barnard on January 17, 2007 at 9:35 pm

  I’ve been trying to correct the slight exposure variations in time lapse imagery captured with a digital still camera and intervalometer. I figured the auto levels and auto exposure effects might be able to do it, but apparently not.

  Basically there is brightness and contrast between the individual images of just a few IRE – just enoght to create an annoying flicker/strobe in the shots when animated. Anybody deal with this?

  I’m Using AE6.5

  Thanks

  It’s very possible it’s the subtle variations of the auto exposure that’s causing the problems in the first place. Depending what’s in the shot at what time, the camera may pick a new value to expose the frame at. I played with what you are doing once and setting the cam to auto exposure and focus was a mistake because of the constant changes. Whereas setting it 100% manual was a smooth result.

  Like Dave said try the Color Stabilizer. But don’t expect miracles from it. It can some time add more variation itself if not set right.
