Visual Look Up Drag and Drop
Visual Look Up already identifies pets, landmarks, and plants and gives you descriptive information about them. However, iOS 16 will take that even further by letting you intelligently extract those objects from your photos to use them elsewhere.
For example, you can touch and hold on an object such as a dog within an image, and then immediately drag and drop only that selected object, without the background, into another app, such as a Messages conversation.
