iOS 17 Facetime Updates

If you are a frequent FaceTime user, you might have noticed a new "F" button after updating to iOS 17. This "F" button in FaceTime makes the background of your video blurry, similar to when you're taking a photo in Portrait mode. In this article, we'll go over what this button does, how to adjust the blurriness of your background when using it, and list more FaceTime updates from iOS 17.

What the "F" Button Means in FaceTime

If you tap the "F" button in FaceTime, the background of your video will get blurry while the foreground will stay in focus. This effect looks similar to a depth-of-field effect you can get on a digital camera when you adjust the aperture/f-stop, and helps frame your face and body better in a FaceTime call.

The "F" button in FaceTime adds a depth-of-field effect to your call. When you tap the "F" button, the background of your video will turn blurry while anything in the foreground (including yourself) will remain sharp.
- You may see this referred to as aperture, or f-stop (as the button has an "F" like the "F" in f-stop), which are both terms used in photography.
- Adjusting the aperture/f-stop of a camera lens is what causes the depth-of-field effect. On the iPhone, this effect is simulated, so the "F" button doesn't actually have anything to do with apertures and f-stop.
