My monumental photos are created by taking a series of photos, panned across a scene, bracketed -2, 0, +2, and then exposure blended and stitched to create a massive, ultra detailed file.  Then I tweak the perspective to create perfect proportion and relationship to the edge of the frame.  The result is an image that can be printed as large as a window with extra clarity while encompassing everything that the scene allowed without being limited to the constraints of a camera format.
