It currently offers four Super-Rotator Tilt/Shift lenses for 35 mm bodies: the TS-PC Hartblei 35 mm f/ 2.8, the TS-PC Hartblei 65 mm f/ 3.5, the TS-PC Hartblei 80 mm f/ 2.8, and the TS-PC Hartblei 120 mm f/ 2.8. It also offers the TS-PC Hartblei 45 mm f/ 3.5 to fit several medium-format camera bodies.
Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions. The most common application for this is the treatment of strabismus.
The same picture corrected. Perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective. The control would: make all lines that are vertical in reality vertical in the image.
The viewfinder used by the AE-1 is Canon's standard split image rangefinder with microprism collar focusing aids. The camera will not function without a battery (one 4 LR44 or 4SR44 cell), including the shutter and lightmeter.
It features a module for camera calibration. DxO's PhotoLab software can correct complex distortion, and takes into account the focus distance. proDAD Defishr includes an Unwarp-tool and a Calibrator-tool. Due to the distortion of a checkerboard pattern, the necessary unwrap is calculated.
Flat-field correction ( FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.
The AL-1 provides focus-confirmation, aperture-priority autoexposure (controlled by a through-the-lens silicon photocell), manual shutter speeds from 1/15 to 1/1000 of a second, and a 10 second self-timer. It also added a larger grip, and the convenience of using of AAA cells for power.
Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data such that the image’s projection precisely matches a specific projection surface or shape.
Where appropriate, prismatic correction can be used, either temporarily or permanently, to relieve symptoms of double vision. In specific cases, and primarily in adult patients, botulinum toxin can be used either as a permanent therapeutic approach, or as a temporary measure to prevent contracture of muscles prior to surgery
Almost every major camera manufacturer enables some form of chromatic aberration correction, both in-camera and via their proprietary software. Third party software tools such as PTLens are also capable of performing complex chromatic aberration appearance minimization with their large database of cameras and lens.
