# Apply an effect

If you want to experiment with an effect, modify a duplicate layer and preserve the original image.

1. Do one of the following:

   - To apply an effect to an entire layer, deselect any selected areas in the image, and then select the layer in the Layers palette.

   - To apply an effect to a portion of a layer, use any selection tool to select the area.

   - To apply an effect to text, select or create text, and use any text effect from the Content palette.

2. In the Effects palette, choose Photo Effects and do one of the following:

   - Double-click an effect.

   - Drag an effect to the image.

   - Select an effect, and click Apply.

Note: In some cases, when applying an effect to an image with multiple layers, you are prompted to flatten the image first.
