Making retro background with photoshop
In this adobe photoshop tutorial we will make a nice retro style effect wallpaper for your desktop.
First drag a gradient across the stage, the color of your choice, just make sure its matte, not bright not dark. Take a look at my green color above.
Now with the pen tool create a spike like I did below, with the color black.
Make a lot of copies and rotate them along the center of the stage like I did in the process below...
Make sure to merge all the spike layers together in the layers panel by selecting them all, right click and choose merge layers.
Now double click the layer containing all the spikes to get into the layers styles panel and give it settings as shown below.
Now just place some object or text in the center of the stage like I did, you can even give it some layer styles like I did below.
The last thing is to make the background a bit dirty, so with a dark color, select a brush that looks a bit like smudge and draw some nice dirt on the background (not too dark).
And we are done..
