![]() Since we’ll be applying an effect that’s normally created using a camera and lens, we need to be careful to choose the right image to make sure the tilt-shift looks photorealistic. This is what we’ll be replicating in Photoshop. Not only does tilt allow you to get more in focus, it also can change the shape of depth of field for creative effect. For example, this feature is popular among landscape photographers as it allows them to get much more in focus when capturing a scene with important foreground and background elements. This can dramatically change the focus plane of an image, allowing you to get objects at different distances in focus. The tilt function of a tilt-shift lens allows you to change the angle of the lens while the sensor remains in its normal position. This means that if you focus on a subject that’s 10 feet away, everything 10 feet away from the sensor will be sharp and in focus. Normally, a camera’s sensor plane and its lens plane are parallel. Shifting up, you can capture the top of the building while avoiding unwanted perspective distortion. Using a shift lens, you can simulate changing the camera’s position. ![]() The lines of the building will seem to converge as they approach the top of the frame. You can change the angle of the camera, shooting up to capture the top of the building, but this will introduce perspective distortion into the image. If you shoot the building straight-on, you won’t be able to capture the entire structure–the top will get cut off. Let’s say you wanted to capture a tall building from ground level. Shift gives you the ability to simulate changing the camera’s position to get more in frame without having to shoot at an angle. The term tilt-shift comes from a type of a lens that allows you to shift and tilt the optics in relation to the camera sensor.
