Now that we’re done with the mysterious light, select all the layers from Step 4 – Step 5 and group these (Ctrl/Cmd + G). Name it to “WALL”.

Step 6: Create the Vignette

In this step, we will learn how to create a vignette which will help enhance the focus on our subject. To start, go to the Menu bar and click on File > New and use the same settings we used to create our canvas. (Refer to Step 1). Take note, the background contents should be white. Once it has been created, go to Filter > Distort > Lens Correction. Find the tab Vignette and use these settings:

Vignette amount: -100
Midpoint: +50

Now that that’s done drag the vignette to our canvas using the Move tool (V) and put it on top of all the layers that we’ve created, and then set the following:

Blending mode: Multiply
Opacity to 40%

To set the blending mode, simply click on the drop-down menu beside the word “Normal” on the top part of the Layer window. The Opacity is located just beside that drop-down menu as well. See image below:
