How to rotate your image while making a path with the Pen tool in Photoshop
When using the Pen tool, hold the R key to activate the Rotate View tool and spin your canvas.
On the surface this may seem superfluous, but will likely prove to be useful for making intricate paths.
When you let go you’ll be taken back to the Pen tool. To level your canvas, hold R and press Escape.
You’ll need to make sure that you have OpenGL enabled through Preferences>Performance to use this tool.
