We arranged a field trip initially to explore how best to capture a suitable series of images. This was followed by a classroom session (thanks to Stacey for use of her classroom) to learn a simple blending technique. The final result should be an image which looks natural and reflects the reality of the scene as viewed by the photographer. We had a subsequent field trip and classroom session to refine our field craft and computer skills.
The first image in the slideshow demonstrates the technique, with a schematic showing before and after thumbnails:-
