The raw images are the lightning picture on http://www.sxc.hu/, another is my photo taken in Nha Trang.


The process is quite simple.
- First, create a new Photoshop file, place the lightning image in the first layer.
- Adjust the image (Image/Adjustments/Curves) to make it much darker.
- Next, using the Dodge Tool (just like the brush), drag it over the small branches of the lightning to make them become clearer.
- Then, apply the layer mask for the lightning layer by changing the layer type into LIGHTEN.
- Now, create another layer under the lightning layer, place the image of Nha Trang Beach in to it.
- Adjust the position of the lightning to fit with the Nha Trang image.
That's it, and here is the final result :
