Text tutorial (by request) :
Step one: Select the paint brush tool, set
Use Color From Gradient: Blinds;
And in brush dynamics: Random: opacity;
Step two: After this, brush the “canvas” until you have a good pattern of rings. (Each circle will become a ring)
Step three: Then duplicate this layer.
Step four: On the original, go to Filters>Distorts>Emboss, and put the settings:
Step five: On the copy, which is the random opacity circles, set the layer mode to “hard light”.
And now you’re done!!!
Step six (optionally): On the duplicate layer, go to Colors>Colorize and toy around with that to color your rings.
