There’s so much more to this tool but I wanted to take it one step at a time.
Here’s the basic functions for the Freeform Pen Tool in Adobe Photoshop.
This tool will allow you to draw out your vector paths with out having to fiddle with it every step of the way. I look at it like the Pencil Tool in Adobe Illustrator.
If you turn-on the Magnetic function, the tool tries to do all the work for you. All you have to do is move your curser along the edge. Check out the video to see it in action!
