And the new Puppet Warp tool lets you distort specific objects in an image while leaving the rest of it unchanged.
This chapter has touched on rotation here and there; you've learned how to rotate a crop box (The Crop Tool), rotate an image with the Free Transform command (Resizing and Rotating Layers), and rotate your whole canvas (Zooming with the Navigator Panel).
