The name derives from extensive use of the technique by American documentarian Ken Burns. The technique predates his use of it, but his name has become associated with the effect in much the same way as Alfred Hitchcock is associated with the dolly zoom.

So now, we know what is the Ken burns effect, but how to do it easily thanks to AppDrag.

That's really easy as you can see in the GIF below. You can apply this effect to background images, you just have to double click on the background image, click on "Animation" then choose the type of effect and duration.

Try it by yourself and tell us if you like the effect.
