  3. Tilt–shift photography - Wikipedia

    en.wikipedia.org/wiki/Tilt–shift_photography

    The 1961 35 mm f / 3.5 PC-Nikkor lens—the first perspective-control lens for a 35 mm camera. In photography, a perspective-control lens allows the photographer to control the appearance of perspective in the image; the lens can be moved parallel to the film or sensor, providing the equivalent of corresponding view camera movements.

  4. 180-degree rule - Wikipedia

    en.wikipedia.org/wiki/180-degree_rule

    Moving the camera over the axis is called jumping the line or crossing the line; breaking the 180-degree rule by shooting on all sides is known as shooting in the round. The 180-degree rule enables the viewer to visually connect with unseen movement happening around and behind the immediate subject and is particularly important in the narration ...

  7. Scheimpflug principle - Wikipedia

    en.wikipedia.org/wiki/Scheimpflug_principle

    Rotating the image plane (as by adjusting the back or rear standard on a view camera) alters perspective (e.g., the sides of a building converge), but works with a lens that has a smaller image circle. Rotation of the lens or back about a horizontal axis is commonly called tilt, and rotation about a vertical axis is commonly called swing.

  8. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    This requires perspective correction only once per each horizontal or vertical span, rather than per-pixel. The Doom engine restricted the world to vertical walls and horizontal floors/ceilings, with a camera that could only rotate about the vertical axis. This meant the walls would be a constant depth coordinate along a vertical line and the ...
