When working with effects, there are a couple of useful things to know that will let you maximize your results. For example, you can rearrange the order of effects applied, temporarily disable specific effects, or even reset all the effects applied to a particular layer.
You can apply effects to layers directly or add them as effects layers. Adding effects directly will automatically link them with the layer to which they are applied. This means that when editing, the changes applied to the layer will also affect the effect and vice versa. For instance, if you try painting on a layer that has some of the Distortion effects applied, the brush stroke have the same distortions as well.
Effects layers work as individual elements you can add to a project and edit separately from the layer (or layers) to which they are applied. Just like applying effects to a single layer, creating effects layers let you work completely nondestructively. Effects layers can be moved freely up or down the layers list and will change the appearance of all other layers below them. Other than that, all the effects controls function the same way as they do when editing layers directly.
To add an effects layer, do any of the following:
Tip: If you'd like to apply an effects layer to only one layer or layer group below it, you can do that using a clipping mask. See Use clipping masks to learn more about working with clipping masks.
If you apply two or more effects to a single layer, you can rearrange the order in which they are combined. For example, if you apply a Gaussian blur effect and a Kaleidoscope effect, putting the Gaussian effect on top will mean your original layer is tiled first, then the result is blurred.
To rearrange effects, click and drag the effect up or down the list of effects.
In the Layers sidebar, click to select the layer you'd like to see without any effect.
Click and hold the Show Original button at the bottom of the Tool Options pane, or press + on your keyboard.
Tip: If you're editing an effects layer, you can also click its visibility checkbox in the Layers sidebar to hide all effects.
Using the Split Comparison view, you can see what an image looked like before and after you applied any effects to it. There are a few ways you can turn on the Split Comparison view:
-click the Show Original button at the bottom of the Tool Options pane.
Press+ on your keyboard.
If you're using a trackpad, force click the canvas or two-finger tap the canvas and choose Split Comparison.
Choose Window > Customize Toolbar and drag the Compare item to the toolbar.
In the Layers sidebar, click to select the layer in which you'd like to turn off an effect.
In the Tool Options pane, turn off the effect you want.
In the Layers sidebar, click to select the layer that has an unwanted effect.
Click next to the effect you want to remove.
Flattening all the effects applied to a layer can be useful when you’re happy with the way it looks and you’d like to resize the layer without the effect repeating beyond the edges of the layer (which happens with Tile effects, for example).
Do any of the following:
In the Layers sidebar, –click a layer and choose Effects > Flatten Effects.
Choose Format > Effects > Flatten Effects.
-click the Reset button at the bottom of the Tool Options pane.
