How to blur an image halfway/not fully in keynote?
Solution 1:
I have tested the following under macOS BigSur 11.4 and Keynote version 11.1, yet I remember this functionality has been there a very long time.
- Select the image you want to blur.
- Select "animate" in the top right corner:
- Right below select "action"
- Click on "add action" and select "opacity"
- You will now have a slider for both duration and opacity
