Introduction to space photography

The technology of obtaining image data and related data of the earth or other stars by using cameras or other remote sensing detectors in space flight. Although it is customary to use the word "photography" here, it not only refers to the way that electromagnetic radiation directly acts on negative emulsion to form images, but also includes other ways to obtain information. Space photography usually adopts panoramic photography, multispectral photography, CCD array scanning photoelectric imaging and radar scanning imaging. Space photography is the expansion and development of aerial photography.
