Step 5
Now we can really just use our imagination and simply duplicate this “lines” layer a few times, rotate and resize each duplicated layer until the outcome is desirable:
Here is my effect so far:


Merge the duplicate layer together.
We can also add a bit of glowing effect to the spectrum lines. To do this, simple duplicate the merged layer and apply the following Gaussian Blur settings: (Filter > Blur > Gaussian Blur)

Change the blending mode the duplicated layer to “Linear light” and you will have the following effect:

To add some final touches, remember we created a new brush preset in Step 1? We can use it to add some nice dots on the abstract line.

Create a new layer called “dots” on top of all other layers, grab that brush preset and simply paint over the lines:

Then Change the layer blending mode to “Overlay” and you will have the following effect:

Duplicate this “dots” layer and change the blending mode of the duplicated layer back to “normal”, then reduce its opacity to 15% and erase some excessive parts.

You will have the following final effect:

Ok that’s it for this tutorial! Of course you can further enhance this image by adding some more effect, textures and filters.

Here is my final version for this tutorial: (Added a bit of cloudy effect and sharpen the image )
