New in Adobe Photoshop CS2 is the Vanishing Point Tool , which lets you clone, paint, and paste elements that automatically match the perspective of the surrounding image area.

1. The Vanishing Point is in the Filter Menu. (Filter - Vanishing Point). After you choose it, a vanishing point window opens.

2. There are two important steps. First we need to draw a grid and then we paint or add what we need in that grid.

3. First we will draw the grid. - On the left menu we have the Create Plane Tool and we select that. After this we just need to mark with points the part of the picture we want to change. So click on the surface and make a rectangular.

Now you have a grid.

If you want to scale it you just pull from the sides points not from the corners.

4. We want to make the bird go away. We will do that by using the Clone tool which is like the stamp tool inside of Photoshop.

With that selected click Alt + mouse and get the source for your clone. Now make it bigger if you need or smaller and in the upper bar menu we have a "heal" option, set it on. Go with your selection over the bird and there we are.

5. The bird is no more and everything is wonderful. Click ok and we are done.
