Then drag them away from the center of the photo as shown here. Then press CTRL Z to undo this nondestructive and unwanted edit Boolean Operations as a Trimming Technique It takes an equal amount of effort but it might be easier to visualize the nondestructive photo-trimming process by drawing the outline of the image object you want to isolate and then to use the shaping commands to slice out the area you want to use. If you have Bach trimmed now you don t have to follow this tutorial but do read the steps because you might find this technique easier than editing with the control nodes. Background Removal Technique 2 1. Using the Pen tool with which you re the most comfortable and experienced draw a silhouette around the object you want to isolate in the photo as shown in Figure 24-3. It usually helps if you choose a contrasting outline color as you progress you rightclick in this example black on the Color Palette after you ve begun tracing. Choosing outline and fill colors after you ve begun drawing a shape avoids triggering the attention box asking whether all new objects should get a black outline. 2. After you ve closed the shape choose Arrange Shaping Shaping to display the docker for performing an Intersect Boolean operation. You could use the property bar shaping buttons to perform this but the property bar shaping buttons by default leave a copy of the target and source objects after the operation a minor hassle to clean up later. 3. Select the object you just drew. Choose Intersect from the drop-down selector and then make sure both of the Leave Original boxes are unchecked. Click Intersect With click the region of the photograph that is outside of the black outline you just drew and you re home free as shown in Figure 24-4.
