The lightning was taken from this image:
http://dslrusers.com/viewtopic.php?t=24475&highlight=
and the original of the pier shot is this:
Basically I did the following things to create the image.
Convert it all to B&W using the desaturate tool. (Always try to create a new layer for each step.)
Lasso the lightning and feather by 50 pixels, then paste into other image.
Matching colours with the two images is very difficult, so from here on in everything was done in black and white.
To match the clouds around the lightning with the rest of the sky, I played with the levels and curves until I got a very low contrast sky, and you could barely see the lightning.
Then merged all visible layers, duplicated that layer and increased the contrast of it to enhance the lightning as well as darken the sky. Add a layer mask and do a straight gradient to blend the sky into the foreground.
Then fiddled with contrast of foreground layer to get it to match the mood of the sky.
Added a vignette by creating new blank layer dragging oval marquee around the image, inversing, feathing by 250, then filling with black and reducing opacity to about 60 or 70.
As I mentioned, somewhere along the line early in the piece I did a diffuse glow on the image, which stuffed up the pole on the pier.
Sheepie: that pano is a good idea, and just did a quick preview and it works... thanks for the idea
