Video Tutorial: Ansel Adams style B&W conversion

Some time ago I took part in an online photo challenge to produce an Ansel Adams style image. This is the image I produced.

As a result of the very kind comments I received about it and the many questions regarding how it was done I decided that the best way to show the process was to create some screen videos. You can view the videos and an explanatory page at http://www.photowalkthrough.com/tutorial_1/.
