4. Paths & Pen Tool 
While this series is optional and is not related to any particular lesson from the text, I strongly advise experimenting with the Pen Tool and Vector functions in Photoshop in order to increase your skills in creating vector objects and also to employ as an alternate method for selecting objects. View in sequence, this series of Flash movies on-line or download the whole series to your hard drive to view off-line. If you download, after un-zipping the shell folder, view the "whyusepen" video first, which is the intro movie. Then view the others sequentially; 01, 02, etc. Also download the templates (Practice_Paths.zip) folder which includes the templates I use in the tutorials on how to use the Pen Tool in Photoshop. You can use these templates to practice drawing with the Pen Tool. Be sure to click the Paths tab in Photoshop, which is usually nested with the Layers Palette, or go to Window>Paths, while working with this Vector drawing tool.
Intro to Vector Paths: (Flash Movie 6:16 minutes)
01_Straight Paths: (Flash Movie 10:24 minutes)Shows you how to use the Pen tool to create straight line paths.
02_Closed Curved Paths: (Flash Movie 3:42 minutes)Shows you how to create bezier curves and closed paths.
03_Straight Curved Paths: (Flash Movie 6:57 minutes)Shows you how to combine straight paths with bezier curved paths.
04_Edit Paths: (Flash Movie 15:18 minutes)Shows you how to edit a path after you've created it, using Add Point, Delete Point, the Direct Selection Tool, and the Convert Anchor Point Tool.
The series begins with an example of how a vector shape differs from the same shape on a regular pixel layer. Showing you how using the Free Transform tool on both produces very different results. The pixel layer degrades while the vector layer remains sharp and crisp. The same result occurs when the file is upsampled or downsampled.
Using the Vector drawing tools (the Pen, Shape, and Custom Shape Tools) with their vector options checked is an alternate way to create logos in Photoshop, without having to jump to Illustrator You can also use Vector Clipping Masks in lieu of 8-bit Layer masks if your preference is to have a very sharp crisp edge, as opposed to a softer one which is the nature of the 8-bit Layer mask.
Unlike 8-bit Layer masks and regular pixel layers, you cannot apply filters to Vector Shape Layers or Vector Clipping Masks.
