Do not fill this in! === Two-dimensional images === The word 'image' is also used in the broader sense of any two-dimensional figure such as a [[map]], [[Graph (data structure)|graph]], [[pie chart]], [[Painting (object)|painting]], or [[banner]].{{Clarify|date=November 2023|reason=This is contradictory to the previous assertion that images can represent non-real concepts, which includes all of the forms described in this sentence.}} In this wider sense, images can also be rendered manually, such as by [[drawing]], the art of painting, or the [[graphic arts]] (such as [[lithography]] or [[etching]]), rendered automatically by [[printing]] or [[Computer graphics workstation|computer graphics]] technology, or [[Image development (visual arts)|developed]] by a combination of methods. A two-dimensional image does not have to use the entire visual system to be a visual representation. An example of this is a [[greyscale]] ("black and white") image, which uses the visual system's sensitivity to brightness across all wavelengths without taking into account different colors. A black-and-white visual representation of something is still an image, even though it does not fully use the visual system's capabilities. On the other hand, some processes can be used to create visual representations of objects that are otherwise inaccessible to the human visual system. These include [[microscopy]] for the magnification of minute objects, [[telescope]]s that can observe objects at great distances, [[X-ray]]s that can visually represent interior structures of the human body (among other objects), [[Magnetic resonance imaging|magnetic resonance imaging (MRI)]], [[Positron emission tomography|positron emission tomography (PET scans)]], and others. Such processes often rely on the detection of [[electromagnetic radiation]] that occurs beyond the [[Electromagnetic spectrum|light spectrum]] visible to the human eye, converting such signals into recognizable images.
