Control
First look at the effect of the picture:
First, the foreground color is white, the background color is black, a new layer is created, I use a selection to create a few rectangles, and then use a gradient to fill the selection with the 45 angle, up and down, and then the radial gradient, symmetrical gradient.
Of course, you just need one of them.
Then with the filter--rendering--layered clouds, you will find that the lightning is along the gradient of black and white demarcation line, so that the direction we can control.
Now, we can do it by using the usual lightning-bolt method.
First, the reverse phase.
Then there is the brightness and contrast, which can be performed two times respectively, to make the lightning lighter.
The above figure is the second time to adjust the brightness contrast, only adjust the contrast on the line.
Then the hue saturation is used to color the line, of course, in other ways to paint.
