How do I fix this lighting issue?

[Dinosaursandanime65]

Whenever I’m making a stop motion, the lighting will randomly change on its own. At first, I thought it was just because of the open windows letting sunlight in but apparently not. Two weeks ago when I started filling my first movie, the lighting was still a problem. It would change from what I think was normal to like an orange-ish tint and this was at night this time so there was no sun to intervene, and everyone else was in the rooms doing their own.

I think its a problem with the camera.

If its on Automatic it will change the settings to get the "best" result, which ends up being different.

Use manual settings and save them, you should get more consistent results.
It may take several testshots to find the sweetspot and you may also need to switch to manual focus, however this may be the best solution.

Obviously does depend on the camera you are using and the lights.

Maybe you can also change it with photoshop or other image editing software later, but this takes a while with 10.000 pics.
