In the Layers palette, select the Background layer.

In the Channels palette, drag the Egret channel to the Load Channel as Selection button () at the bottom of the palette. Before continuing to the next step, make sure that the RGB channel is selected, not the Egret channel.

3.

Choose Select > Inverse.

The previous selection (the egret) is protected, and the background is selected. You can now apply changes to the background without affecting the egret.

4.

Click the Layers palette tab and make sure that the Background layer is selected. Then choose Filter > Artistic > Colored Pencil. Experiment with the Pencil Width, Stroke Pressure, and Paper Brightness sliders to create an effect you like.

NoteIf the Filter menu is not available (dimmed), you may have accidentally selected the Egret channel when you dragged it to the Load Channel as Selection button. To try again, choose Select > Deselect now and make sure that the RGB channel remains selected when you load the Egret channel.

Click OK when you're satisfied with the Colored Pencil settings. The filter is applied to the background selection.

You can experiment with other filter effects for the background. Choose Edit > Undo to undo your last-performed operation.

Choose Select > Deselect to deselect everything.

Before you save your file, you'll flatten your image to reduce the file size. Make sure that you are satisfied with the image before you go on to the next step, because you won't be able to make corrections to the separate layers after the image is flattened.

Choose Layer > Flatten Image, and then choose File > Save.
