Step 1: Start off by opening Photoshop, and than opened your desired image. File -> Open.
Step 2: Now go up to Image -> Adjustments -> Desaturate or you can just hit
(CTRL + Shift + U) on your keyboard.
Now you probably have noticed, your image is now Black and White, you can pretty much say your done, but I liked to
add a little effect.
Step 3: Now you need to duplicate the layer. Layer -> Duplicate Layer... and just hit "Ok" to the defaults. Or the
easier method is to drag your layer onto the new layer icon.
And you should now have this.
Step 4: With your new layer selected like above, go up to Filter -> Blur -> Gaussian Blur.
Put in a 5px radius and hit "Ok." You should have something like below.
Now change the blending mode to "Overlay" and the Fill to 50%.
