Today I was watching some video tutorials and I found out about Vanishing Point.
Vanishing Point lets you clone, heal, select something that is not quite easy to select using just Marquee tool and transform objects. You’ll find this tool in Filter menu.
I'll take this picture below and I’ll show you an example of what you can do with VP :)
Open the picture in Photoshop (you can find this tool only in Photoshop Cs2 or Cs3). Make a new layer – in which Photoshop will put your result. Then go to Filter – Vanishing Point.
Go to the toolbox in the left and select Create plane tool. It’s usually selected.
Put your mouse pointer in the right corner at the top of the window from the right side of the picture and click. Click again on the left corner of the window from the left side, like you see in the picture below.
Fallow the line going down and then to the right, then back from where you start. 
Now zoom in if you think you have to adjust where the points should be. For the next step I’ll select the window from the right side. To make the selection easier so I don’t have to zoom and see if my selection is ok I’ll select the Transform Toll in order to increase the size of the grid and then to be able to select the area around the window.
Just like using the Transform tool as you usually do, drag the grid up, down, and to the right. 
Now select Marquee Tool and select the window.
In order to duplicate the window press Alt key and drag it to the left.
You’ll notice you can move it all around but you have to pay attention to align it in line. If you press Shift key while you press the Alt key it will be much easier to position the window in line with the others. 
Ok .. so far so good.
But because I selected outside the window too, I have now a piece of the shadow from the original window. That’s good because that way I can show you how to use the Stamp tool. The way you’ll use it is pretty much the same way the Stamp Tool always worked in Photoshop.
Select the tool and hold down Alt key - you’ll notice a little cross. Wherever you’ll click with that cross is the area that you want to patch with. 
So click next to the window, on the yellow wall and then release it and pull over where you want a stamp of that area. Click again to patch that out. You also can adjust the diameter of the Stamp tool.
In the image below you can see that the Heal is turned on and we don’t want that in this case. Turn it off and do it again.
Click Ok.
You will see that Photoshop put the new window in the layer you created at the beginning.
Here is the final photo:
And here is another way to use Vp. I hope you liked it !
