step 6 Right, drag the wall layer down over the 'Create New layer' icon to copy it (circled red). Then CRTL+T, right-click and choose 'Flip Horizontal'. Now move the copied wall over a bit to line it up:
step 7 Wow, a corner. I don't want a corner. Still in transform mode, right-click again but this time choose 'Perspective'. Play around with the angle until you have something like this. When you're happy with it, CRTL+E to merge the two wall layers.
step 8 Ah! But the bricks are repeating! So they are. Well I guess it's time for the Vanishing Point. Click Filter and choose Vanishing Point from the menu. A screen pops up. A really big screen. First thing to do is zoom in. Now click the 'create plane tool' and click each of the four corners of the wall in turn. Very important! The grid that appears has to be blue. If it is red or yellow it's no good. You will have to play around moving the corner points until it changes color.
step 9 Now is it blue? Good, we can continue. Click the Clone tool, then ALT+Click part of the wall you want to clone. It's a good idea to ALt+Click in between the bricks, so it's easier to line up. Notice how big the clone brush is?
step 10 Now if we move the clone brush to the other end of the wall, is changes size! So now we can clone pieces of the wall in perspective! That's what the vanishing tool is all about! Try to only clone one brick at a time, and do it slowly! This takes lots of practice to get right, and don't forget CRTL+Z to undo!
