Then choose Filter > Render > Clouds and set the
layer containing the clouds to
the Difference mode.
Then choose a large soft brush and paint with black on the bottom layer.

around the edges of
the areas you painted.
When you have finished creating lightning, choose Layer
> Merge Visible
to combine all of the layers, and then give this image a name and save
it.
