How do you edit an effect?

[umizoomi]

When applying an effect. You can select some attributes, depending on which effect is chosen.

I am wondering. As you don't see the changes in realtime. How can I edit added effects?

You can see changes in real time in small preview. But editing depends on effect type:

• destructive: once effect is added, you can do Undo and add it again.
• non-destructive: you can change effect parameters any time by clicking on effect name in Layers list on right sidebar, see attached image.
