Tilt-shift demo #2
Second photo, tilt-shift demo. The lens has been tilted and the focus plane moved so that it is completely horizontal. Aperture is still wide at f4. Note how a band of the cairn is in focus, as well as the mountains on the horizon. Everything above and below is progressively out of focus. To focus on points both so close and so far simultaneously in this manner is virtually impossible with a non tilt-shift lens.
