Glad you like the shot - the process was a follows:
- open RAW image in Photomatix and use tone mapping
- use tone compression tab and adjust sliders for one part of image
- process file and save as *****image1.jpeg
- open RAW image again in Photomatix and follow above process but adjust sliders for sky
- process 2nd image and save as ****image2.jpeg
- repeat again if required - i only used 2 shots for this shot
- open both shots in Photoshop(i used Elements) and combine in one image
- i then selected sky and used background eraser to take out one sky to show through other
- then adjust shot with levels etc until you are happy
Hope this explains things
