When creating a stop motion movie we need take a lot of pictures to build the movie.

But after we took the pictures, we have a problem: the brightness and contrast varies between pictures.

What kind of tool can we use to normalize these levels? For example, if we decide that a picture of a defined scene is a good one, how we can automatically, for all pictures taken, normalize the brightness (and contrast) to be compatible with this predefined good picture?

A solution using a free or open source tool would be better for us. Or a script than we can run on a folder, for example. The stop-motion aims to encourage the people ride bicycles.

But if there is a paid solution, we would like to know too.

Thanks in advance.

You can try this: http://www.granitebaysoftware.com/products/productgbd.aspx

It claims to do what you need (Although I have no experience with it) by normalising a sequence as either an Adobe plugin (Premiere or After Effects) or as a standalone application.

  • Could be interesting if it works on masked sections in affter effects. :o) – Rafael Jun 2 '15 at 14:05

Use full-manual mode to lock in the aperature, time, and iso. If you let the camera choose, they will be differences not just in brighness (easy to fix) but perspective and noise.

  • Thanks about the comment. The truth is we already done this, but the studio is not a professional one, so some other lights that we not control unfortunally messed the things a little. With a time limitation, we will can not re-record everything, but we need to fix the brightness of each image that we have. So we are looking for a solution that can fix the brightness after we have a brightness distortion, instead of a technique to avoid this problem. Do you know something that can help us? Thanks a lot. – GarouDan Jun 1 '15 at 2:53
  • You ought to update the question. If I understand you, you did use a fixed set of settings on the camera, but the lights changed? – JDługosz Jun 1 '15 at 3:16

Full manual, and of course, fixed lighting that does not vary.

    How would one go about making sure that the lighting does not vary? – mattdm Jun 1 '15 at 3:05
  • Why would it change? Is the lamp flickering? I would not expect it to change during the working session if nobody moves anything. And tape marks help in case somone trips over a stand. – JDługosz Jun 1 '15 at 3:19

Ok. The exposure is not the problem. The exposition on the inside of the elevator is the same.

The problem is that you blocked the exterior light!

The only option I see is that you manually adjust not all the image, but some zones, masking them.

Use this program: http://www.gimp.org/

You will need to have one photo as a reference and the other modified but only in the exterior area, and probably the back of the guy.

I'm afraid you need to make adjustments "by eye".
