The Vanish Point Filter is one of the most useful filters in Photoshop. Vanish point can be used to create perspective within your existing photos or to apply them on special surfaces. You can even use it to extend and modify existing object like the exercise below.

Strating from a skyscrepers picture, Click the “Create a New Layer” button at the bottom of the open layers palette. Choose the “Filter” menu and click on “Vanishing Point” to open up the “Vanishing Point” filter in a new window.

Choose the “Create Plane” tool and click in four places on your photo. These four points will define the place where you want to extend the part of your photo to where it will vanish. After placing your four points, they will create a blue grid of rectangles.Select the “Edit Plane” tool from the “Vanishing Point” window and click and drag the corner points to change the perspective and the center points to extend any grids. You can also add additional grids to join together with your first grid.Use the Marquee tool, Stamp tool and Brush tool to make any changes to the photo and the vanishing point.

The results you can achieve depends most on the initial photo and perspective.

Using Vanishing point you can apply pictures on solid surface as well like in the next example.

Vanishing point is also very useful in the mock-up and presentation of packaging. Once your object is applied on your surface you can modified it using every tool from the tool palette, you can change colors or shadow or whatever you like.
