Summary:

• **What is a variable aperture?** Apple is planning to add a special camera feature to the iPhone 18 Pro that can change how wide or narrow the camera's opening is, kind of like how your eye's pupil gets bigger in the dark and smaller in bright light. This helps take better photos in different lighting conditions.

• **Why is this cool?** With this new feature, iPhone 18 Pro users will have more control over their photos, letting them take clearer pictures when it's dark outside and also take special photos where the background is blurry but the main subject is sharp and clear.
