One of the great things about the Pen Tool is that it's not something that's exclusive to Photoshop. Far from it! Virtually every popular photo editing, graphics and page layout program uses the Pen Tool in one form or another , so once you've learned how to use it in Photoshop, you'll already have a good understanding of how to use it in lots of other programs as well!
Where Do I Find The Pen Tool?
Before we start talking about what the Pen Tool is or how to use it, we should look at where to find it in Photoshop first. You'll find the Pen Tool in the Tools palette, grouped in with the Shape Tools, the Type Tool, and the Path Selection (the white arrow) and Direct Selection (the black arrow) Tools (see the image on the left).
