How do I extend a frame's exposure, and be able to change each frame without changing all of the frames?

I would like to have the same image running for a few seconds with a few changes to each frame like hair moving a bit as if it’s blowing in the wind, however when I extend the exposure of one frame, and change each frame in the exposure slightly, but once I change one frame, all frames in the exposure are affected. Thanks for any help :slight_smile:

Is the animation done in frame by frame or transformed by a peg? By reading it, you are animating frame by frame, but I am confused ‘change each frame in the exposure slightly, but once I change one frame, all frames in the exposure are affected’ how this has been done.
