Releasing the keys switches you back to the standard Free Transform mode. To switch to Perspective mode, hold down Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) while dragging a corner handle. To switch to either the Skew or Distort mode, just hold down your Ctrl (Win) / Command (Mac) key as you drag a side or corner handle. With Free Transform active, you can temporarily switch to the Skew, Distort or Perspective modes directly from the keyboard without having to select them from any menu. Selecting Skew, Distort And Perspective From The Keyboard Perspective mode can create some simple 3D-style effects. Just as we've seen a couple of times already, if you include the Alt (Win) / Option (Mac) key as well, you'll resize it from its center: To resize something with Free Transform, hold down your Shift key, which will constrain the aspect ratio and prevent you from distorting the original shape, as you drag any of the corner handles. You don't want the person in the photo to suddenly appear tall and skinny or short and fat because you've reshaped the image. For example, you may need to make a photo smaller so it fits better in a collage or other design layout.

Sometimes that's what we want, but more often, we just want to resize something, making it smaller or larger overall but keeping the original shape intact. They may be wider, thinner, taller or shorter, but they no longer look the way they did originally.

One potential problem when reshaping things with Free Transform is that, well, we've reshaped them. Drag any of the corner handles to adjust the width and height together.
