Step 11 At this point, we have a good idea of what the final composition will look like. Create a ‘Curves’ adjustment layer at the top of the layer panel. In the RGB channel selection (Alt + 2), set the Output to 10 and the Input to 0; this will reduce the black density.
Step 12 Still in the ‘Curves’ adjustment layer, go to the Blue channel (Alt + 5) and set the Output to 7 and the Input to 0. Now the dark areas will have a very slight and subtle blue tone.
Step 13 Let’s add some abstract shapes to the mix. Inside a new group, select the Line tool (U) and, with a 6px white line, start drawing some geometric shapes in the upper-right part of the composition. Add a Layer mask to it, and brush out some of the shape.
