Selecting Circular Shapes with the Pen Tool
The first thing you'll need to do before merging images together is to correctly isolate the individual elements of the image(s) you need so that they merge together seamlessly. I typically use the Path tool for selecting my images. When creating a clipping path with the Pen tool, make sure you use as few points as you can get away with to select your shape or image. For instance, as you can see in Figure 6-1, accurately selecting a perfect circle should require no more than four points to complete.
