Now to the object of this exercise - the shadow. If you look at the statue
you'll see he looks pasted on because there's no shadow. This can be created
easily using a few steps. There is a drop shadow option in Photoshop but
this puts a shadow around the subject and not at the angle we need.
Before you start take a look at the shadows of objects in the shot. Here
the table and chairs have shadows below and to the front right. These
are produced from the sun coming through the skylight window.
Duplicate the ornament layer by dragging it to the layer icon in the
layer palette or click it and select Layer>Duplicate Layer from the
menu. With the duplicated layer active go to Image>Adjustments>Threshold.
