[NEED HELP] eliminate Timelaps flickering ???

I shot some timelapse with a digital photo camera. Everything was set to manual an I use some lamps for same lighting conditions but the pictures are a little different in level/brightness. If I play this timelapse, it has a flickering - some more, some not.

How can I eliminate (or reduce) this flicker? Any ideas or tutorials?

Thanks for any help!

Hmm.. perfect solution is to adjust each picture separetely.

Else you can use an adjustement layer and fix the parts that flicker compared to the previous frames.
 
if you have a recent photoshop, do a batch process and use the automatic adjust actions!
 
Thanks a lot BUT…

The "perfect solution" and the adjustment layer are not practicable because there are hundreds of pictures. The automatic adjust actions in PS are not working right because in many photos are no black or white. Any other suggestions?
 
well you're welcome... part of the "look" of time lapse is sometimes a flicker. if that isnt what you are looking for you'll need to tweak the offending frames.. or try throwing a broadcast safe filter on there and clamp it down untill it does something. but it may not do much if the bad frames arent far enough from your mean..
 
timelapse is really tricky for a number of reasons. most importantly you have to set up your camera correctly when you shoot the innitial sequence.

I can deduce from you saying you have flickering (and I'm assuming that means each exposure is different) that you didn't "lock" the settings on your camera before starting the sequence. This is the most common mistake in making timelapse sequences when using a still camera rather than a video or film camera.

What happens is for each of the frames the camera does a new light measurement and adjusts accordingly. So for instance if you're shooting a cloudy sky and a white cloud is in frame it adjusts for the white while if a darker cloud or the sky is in frame it adjusts for that. thus you get a number of differen exposures and you end up with a flickering movie.

the only good way of solving this is to lock your camera - which means you need a DSLR or simmilar that has complete shutter and apperture control. if you do, just spot meter on whatever is the most predominant feature in your video and lock the camera to that setting.

it won't completely solve the problem - in bright sunlight you will have flicker regardless - but it'll take away the most violent flickering and make it appear smooth.

Thanks everyone!

@Heroic: Works not perfect but better than nothing!

@morten: I use a Nikon D100 and as I wrote, EVERYTING was set to manual. I shot the sequence with the same settings (shutter, apperture, WB etc.) from the first to the last picture.

I finally finish the sequence, here is the final result: http://www.revostock.com/FileCloseup.html?&ID=4959
 
so the lighting was studio, the settings were locked down on manual, and you still got flickering?
 
Right, the difference was mostly in the green underground. Not huge but enough to flicker...
