In this tutorial, we will teach you how to recreate the shimmer effect of the force field from the movie "Annihilation" using Adobe After Effects.

**Step 1: Import Your Footage**
Begin by importing your footage into a new composition in After Effects. You can use your own footage or download the footage used in this tutorial to follow along.

**Step 2: Track the Motion**
Track the motion of your footage to ensure the shield effect stays consistent with the movement in your scene. Analyze and track the scene fully before adding the shield.

**Step 3: Create an Adjustment Layer**
Create a new adjustment layer for adjusting the sky. Use the pen tool to mask around the sky and apply feathering to blend the effect smoothly.

**Step 4: Darken the Sky**
To make your shield more visible, darken the sky using the color correction curves effect. Adjust the curves until the sky is sufficiently darkened.

**Step 5: Adjust Colors**
Customize the color of your shield and the sky until you achieve the desired effect. Play around with different settings to get the perfect look for your footage.
