It certainly works well on this type of landscape. I wonder what results you would get on very different kinds of images.
You can find the technique here on this site: http://www.andregallant.com/new_galleries/...s/montages.html
It doesn't work too well with dark images or images with too much black areas. You can see many examples on my site @ http://lusalight.smugmug.com/
The bottom line is to try it, and it either works or doesn't for certain images.
