The images we inflated on the previous pages both ended up with flat bottoms, because that’s more or less the way these objects are. But what of more rounded items, such as the pear in this photograph? We need a way to inflate this on both sides for a realistic view of the object.
Before we inflate it, though, let’s look briefly at the best way to cut the image from its background.
This is the original photograph of the pear, and you can download it from 3DPhotoshop.net.
Drag the Quick Selection tool over the outside of the pear to select the background. This is easier to select because it’s so uniform.
Use Select > Inverse so that the pear is selected. Hold when dragging with the Quick Selection tool to subtract the shadow from the selection.
To clean up the selection, choose Select > Refine Edge or use the keyboard shortcut . The background may appear as black, white or a checkerboard, depending on how you last set up the dialog.

In Refine Edge, you can view the cutout in a variety of ways. Press to view it against a black background, which makes the cutout easier to see.
Drag the Smooth slider until all the little bumps and wrinkles disappear from the outline of the pear. This will make it much easier to extrude successfully
Smoothing the edge will also make it a little fuzzy, so drag the Contrast slider until the edge becomes crisp again.
Then click OK to return to the pear as a smoothed selection, and use to make that selection into a new layer.
