The first picture was taken with a white sheet as the background:

The image itself was sharpened in Photoshop, then the background was removed by a combination of cut /paste and flood fill of a solid color:

This picture was then softened using the "unsharpen mask", then artistically rendered using the poster edge and ink outline features. The result of all this changes the picture from a photo into a work of art. If only I could do this by hand -----

Of course, I already think this Pete is a work of art ----
