The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...
Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]). The same techniques are equally applicable to video.
Whereas manipulating photographs with tools such as Photoshop and GIMP is generally skill-intensive and time-consuming, the 21st century has seen the arrival of image editing software powered by advanced algorithms which allow complex transformations to be mostly automated. [13]

Traditional analog image editing is known as photo retouching, using tools such as an airbrush to modify photographs or edit illustrations with any traditional art medium. Graphic software programs, which can be broadly grouped into vector graphics editors , raster graphics editors , and 3D modelers , are the primary tools with which a user may ...

Compressing this high dynamic range into a print either requires uniformly decreasing contrast (making tones closer together) or carefully printing different parts of an image differently so that each retains the maximum contrast – in this latter dodging and burning is a key tool.
