![]() ![]() With the focal plane as a diagonal, it’s also possible to have two objects that are parallel to one another, with one item in focus and another not. ![]() This creates the appearance of a much deeper depth of field than shooting a traditional lens at the same aperture. Tilt the lens, and the focal plane tilts as well, becoming a diagonal line, instead of one that’s parallel to the camera. On a normal lens, the focal plane is parallel to the camera. Traditionally, anything the same distance from the camera as the subject will appear in focus-that’s because those objects lie on the same focal plane. Tilt shift lenses also allow for greater control over an image’s depth of field.When shooting a sequence of images to stitch together a panorama, a tilt shift lens prevents the parallax error where the horizon appears to bend. While architecture is the most obvious use of a tilt shift lens, many other subjects can benefit from what a tilt shift has to offer.Adjusting the angle of a tilt shift lens can reduce the feeling of looking up at that building. Often, it’s impossible to get far enough away from a building in a crowded city to photograph the structure without pointing the camera up. A tilt shift lens will also make a building appear more imposing by straightening out that perspective. In architecture, it means straightening out lines that appear crooked because of the perspective. The ability to change the position of the imaging circle has more than one application.Where most lenses have degraded image quality at the edges, a tilt shift lens, even when pointed straight ahead, tends to have more uniform image quality. That’s a necessity so that you’re still getting an image when the lens is tilted. Most lenses capture a circle that’s just big enough to cover the sensor, but a tilt shift lens casts a much larger circle.What Are The Benefits Of Tilt Shift Lens? In the CreativeLive course, Nature and Landscape Photography, John Greengo expertly demonstrates this difference: Walls that are straight may actually look crooked because of the lens’ perspective tilt shift lenses can change that perspective, making those walls straight again. That makes tilt shift lenses a big help for architectural photography. The camera body remains in the same position, but the tilt shift adjusts the lens’ perspective. By tilting the lens, you change the center of that imaging circle, which can straighten the lines that appear to converge in the distance. What Is a Tilt Shift Lens?Ī tilt shift lens allows the photographer to change the position of that imaging circle. ![]() Normally, the lens’ imaging circle is fixed in relation to the camera sensor’s position. A lens captures a circular image, but since it’s projected onto a rectangular sensor, it renders a rectangular photo. So, what is a tilt shift lens, exactly? And what are the best uses for one?įirst, a quick refresh on how a traditional camera lens works. Add a tilt shift lens to the front of your camera, and you open up possibilities for altering that perspective. ![]() That’s what helps us perceive depth in a two dimensional image.īut, that’s with a traditional lens. Snap a photo of the same road, and you’ll get that same look. If you are standing in the middle of a road for example, the road appears to shrink as it heads off in the distance. While a camera is a bit different than the human eye, when it comes to perspective, a traditional lens comes pretty close to capturing what we see as we see it. ![]()
