Simulating a zoom lens using Exponential Scale (Pro only)

You can simulate a realistic acceleration of a zoom lens when working with 2D layers by using Exponential Scale, which converts linear scaling of a layer to exponential scaling. This is useful for creating a cosmic zoom, for example. Zooming optically with a lens is not linear--the rate of change of scaling accelerates as you zoom. To simulate this acceleration, Exponential Scale converts the velocity of the scaling to an exponential curve.

To apply Exponential Scale:

1. In the Timeline window, hold down the Shift key and select starting and ending keyframes for the scale property.
2. Choose Animation > Keyframe Assistant > Exponential Scale.

Note: Exponential Scale replaces any existing keyframes between the selected starting and ending keyframes.
