Dan Mountford.

Came across on Dan Mountford's images on Ffffound. Mountford is a British designer and student who has created some fantastic photography using double exposure.
On Mountford's Flickr it states that these double exposures are done in camera, then slightly edited in photoshop (the colours, tones etc.).

I could apply this technique of the blending of images to my panoramic image, using photoshop.
