'''Magnification''' is the process of enlarging the [[angular diameter|apparent size]], not physical size, of something. This enlargement is quantified by a size ratio called '''optical magnification'''. When this number is less than one, it refers to a reduction in size, sometimes called '''''de-magnification'''''.

Typically, magnification is related to scaling up [[visual]]s or [[image]]s to be able to see more detail, increasing [[angular resolution|resolution]], using [[microscope]], [[printing]] techniques, or [[digital processing]]. In all cases, the magnification of the image does not change the [[perspective (graphical)|perspective]] of the image.
