How to zoom in on picture in Apple Keynote
This can be done using the scale animation. If you are using iOS, you can add this by taping the image, tapping the animate button, tapping add action button, and selecting the “scale” animation. To change the duration and scale of the animation, tap the image again, tap animate, tap on the scale animation you just added twice, and a menu should appear, giving you more settings for your animation.
