Answers.Text: Yes, I used fixed manual exposure, all sequences were done in studio using flash units. For some reason there are some differences in some parts of the sequence so I guess maybe there was a problem with the current. The easy way, or less hard way, I believe, is using Lightroom to make these small adjustments. Anyway, thank you for your reply.

Answers.Text: @Nicoli - if they were manual exposures, then you might actually get improved results from using a batch operation to do Auto-levels in Photoshop, though you may still have gamma problems if the mix of light actually changed between ambient and flash due to the level of flash power changing.

Comments.Text: To help in the future, you said in comments below you used manual exposure. The flicking is coming both from variation in the light source itself (sun passing through clouds/dust in atmosphere), but also the aperture of the lens. Set your aperture, and whilst holding the "Aperture Preview" button on your camera, unscrew the lens, as if changing it - about 15 degrees is enough. The lens can't communicate with the camera, and the aperture is stuck in the correct, unchanging position.

  I have created some time lapse animations using my Canon EOS camera.
  
  When I imported these sequences to premiere I noted small changes in luminosity between some frames.
  
  Is there any way to correct these changes inside premiere? Maybe something similar to camera stabilization but for luminosity?
