Not only can you blur any desired part of your image and highlight the subject, but it also helps you adjust the depth of field to enhance contrast within the image and make the image stand out and professional easily. Now, Fotor’s photo editor offers you its Tilt-Shift function to blur image backgrounds with ease, even you are amateur. The Blur background effect is really popular among professional photographers. They are less expensive than their Nikon counterparts.Ĭlick here for the Manual for the 1963 PC-Nikkor f/3.5 lensĬlick here for Nikon's 19mm PC-Nikkor infoĬlick here for Canon's TS-E 24mm f/3.Blur image background to make an image professional On the right, below, is the PC Nikkor 19mm f/4E ED Tilt-Shift Lens, introduced in 2016.Ĭanon has introduced two new lenses with 24mm (left below) and 17mm (right below) focal lengths. On the left, below, introduced in 2008 by Nikon, is its PC-E Nikkor 24mm f3.5D ED lens, which shifts up to 11.5 millimeters and tilts up to 8.5 degrees. The latest examples of these lenses are shown below. Recently, 28mm lenses have been inadequate for some architectural photography, and manufacturers like Nikon and Canon are producing more advanced tilt-and-shift lenses in the wider focal lengths with electromagnetic apertures. The above lenses have been around for some time. Two examples below are the 75mm Pentax-Shift lens for a 6x7 cm medium-format SLR, left, and the impressive Olympus 24mm Zuiko-Shift lens for a 35mm SLR. Several lens manufacturers other than Nikon produce their own versions of PC, shift, and tilt-shift lenses. Exposures must be set with these lenses centered and shifts applied only after exposures are determined. These lenses operate only in the manual mode, meaning advanced SLRs, whether digital or film, must be set to manual. The lenses are shifted upward to simulate how they would be used to bring in the top of buildings while keeping film or sensor planes vertical. In the images below you see 28mm Nikkor shift lens on a 35mm film SLR (single-lens reflex) camera on the left and a 35mm shift lens on the right on an older Nikon film SLR. The first 35mm-format perspective control (PC) lens to correct for perspective distortion to come on the market was the 35mm f/3.5 PC-Nikkor, of 1962. "Tilt" deliberately angles the optical axis so that objects at different distances from the camera can be kept in focus without stopping down aperture, reducing depth of field and ensuring that the background remains blurred. "Tilt" The optical axis of the lens is normally perpendicular to the focal plane. It can be used to reduce the effects of perspective when photographing buildings from low angles or to change the composition without angling or moving the camera. "Shift" the optical axis of the lens away from the center of the frame, allowing photos to be framed anywhere in the image circle. “PC” This is short for “Perspective Control.” Third view, from the same angle, but this time with a shift, or PC, lens gives The house looks like it is falling over backwards. Second shows what results when the same camera without a shift lens is tilted Top of the house isn't in the picture at all. The first photo, the camera has been leveled, but no shift lens was used. Wisconsin, placed on the National Register of Historic Places in 1973. The photo above was taken with a 35mm film camera and a 28mm shift, or PC (for perspective control), lens. However, this will most likely result in the loss of some detail and contrast. This is the best way to do this with a digital camera as well, but similar corrections can be made with digital image editing software on a computer, a technique unavailable when using film cameras. With a film camera you must keep the film plane vertical with a special shifting lens that brings into view the top of the building. Your brain makes the correction when you look at the building, but a camera needs help to do so. In this photograph, note that the vertical lines all are parallel to each other. The photograph above (from the previous web page) is a good example of the solution to the major technical problem a photographer of buildings faces lines converging toward a point, usually upward, to make the building look like it is falling over backward.
