The word "photography" was created from the Greek roots φωτός (phōtós), genitive of φῶς (phōs), "light" [2] and γραφή (graphé) "representation by means of lines" or "drawing", [3] together meaning "drawing with light". [4] Several people may have coined the same new term from these roots independently.

In other words, the camera has a high spectral resolution. The phrase "spectral imaging" is sometimes used as a shorthand way of referring to this technique, but it is preferable to use the term "hyperspectral imaging" in places when ambiguity may arise. Hyperspectral images are often represented as an image cube, which is type of data cube. [3]
The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in wide-screen video. While there is no formal division between " wide-angle " and " panoramic " photography, "wide-angle" normally refers to a type of lens, but using this lens type does not necessarily make an ...
