Perspective Warp is a new feature in Adobe Photoshop CC. While I love the feature, I must object to the name, which is far too bland for something that can take reality and turn it on its head.
Past versions of Photoshop have enabled you, for example, to straighten the sides of an object (see "Before Perspective Warp" later in this article). But no previous tool has given you the ability to virtually walk around an object in your photo, changing the angle of your camera long after you've put the lens cap back on. Once you're familiar with the feature, I think you'll agree that Reality Warp is a more apt description.
For more control, turn your layer into a Smart Object before you apply Perspective Warp to it. This will enable you to adjust the angles at a later point, picking up from where you left off.
BEFORE PERSPECTIVE WARP
Previous versions of Photoshop offered a range of other distortion methods, but none of them could match the magic of Perspective Warp when it comes to this sort of task. The Vanishing Point filter, for instance, can clone and patch in perspective — but you can't use it to distort a whole layer to fit the scene.
Here's how these other tools stack up when given the same task:
WHERE TO GO FROM HERE
The strength of Perspective Warp lies in its ability to manipulate multiple faces of an object at the same time. For a job like this, there's really no suitable alternative.
