What is tilt shift in camera?
The tilt effect alters the focal plane of the image, but the shift effect alters an image’s perspective. With the Shift knob, you can move the lens up and down or side to side on the body of the camera. As the lens moves, the image plane moves too, so that the sensor records different areas of the total image.
