I'll think I'll write something up later, but since later could be a long, long time from now; I'll throw out a quick tip now. If you want to really draw attention to a single area on an object, try messing with the depth of field so that ONLY the part you want to highlight is in focus. Example below:
The smaller the aperture number, the shallower depth of field (the less stuff is in focus around your focal point). Closer focal points also result in a shallower depth of field. Even most point and shoots allow you to change the aperture, but since most point and shoots don't have
