Waves


Step 1

Open your image, then proceed to the Rectangular Marquee Tool.



Where it says Style along the top bar, press the option that says Normal and a drop down menu will appear. Select the Fixed Size option.



Step 2

Match your setting's to mine all except for the Width. You need to set the width to the same size as your canvas. Go to Image > Image Size if you're not sure what the width of your image is.



Step 3

Set your Foreground Colour to your desired one. Preferably the first color of your color scheme.



Step 4

If you've set the width and height correct you shouldn't have any issues here. Using a new layer click anywhere on the canvas and automatically a thin line will show (as shown below).



Step 5

Hold down Alt & Backspace to fill this selection with your foreground color.



Step 6

Now press the Down Arrow Key on your keyboard 4 times so the selection moves underneath the first color. Select your new foreground color and hold Alt & Backspace to fill the selection with that color.



Step 7

Press the Down Arrow Key another 4 times so the selection sits underneath the 2nd colour. Select your 3rd colour from your color scheme and hold down Alt & Backspace to fill the selection with that color.



Step 8

You've probably got the hang of this by now but for those who want guidance I'll explain the process again. Press the Down Arrow Key 4 times so the selection sits underneath the 3rd colour. Now select your 4th colour from your colour scheme and hold down Alt & Backspace to fill the selection with that color. Then press Ctrl & D to deselect the selection when you're done.



Step 9

Now go to Filter > Distort > Wave....



Step 10

These are my wave setting's but feel free to play around a little and experiment with different settings until you find the one you like. If you're happy with these setting's press "OK" and then you're done.
