In this tutorial, we will show you how to give yourself angel wings in your footage using Adobe After Effects. Follow these steps to achieve a realistic angel wings effect.

**Step 1: Prepare Your Footage**

1. Shoot your footage ensuring you wear a shirt with a logo or image that can be easily tracked. This will help in attaching the wings to your body movements accurately.
2. Import your footage into Adobe After Effects.

**Step 2: Find and Isolate Angel Wings**

1. Search for high-resolution images or footage of wings from the internet. Choose wings that do not have too much motion blur.
2. Import the wings into After Effects and use the **Pen Tool** to isolate them. Create multiple variations and layers of the wings to make them look more realistic.

**Step 3: Track Your Body Movements**

1. Select your footage and go to the **Tracker** panel.
2. Use the **Track Motion** feature to track the logo or image on your shirt.
3. Apply the tracking data to a null object which will act as the reference for the wings.

**Step 4: Attach the Wings to Your Body**

1. Place the isolated wings into your composition and position them on your back.
2. Parent the wings to the null object containing the tracking data. This will ensure that the wings follow your body movements.
3. Adjust the position, scale, and rotation of the wings as necessary to make them look natural.

**Step 5: Refine and Add Realism**

1. Use the **Roto Brush Tool** to refine the edges of the wings and blend them seamlessly with your body.
2. Add shadows and highlights to the wings to match the lighting of your footage.
3. Apply motion blur to the wings if your footage has any movement to make them look more realistic.

**Step 6: Final Adjustments and Rendering**

1. Review your composition and make any final adjustments to the tracking, positioning, and effects.
2. Once satisfied, render and export your composition by going to **Composition** > **Add to Render Queue**. Choose the appropriate settings for your final output.
