Magnification

Common card · No. 296180

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a size ratio called optical magnification or magnification ratio. When this ratio is less than one, it refers to a reduction in size, sometimes called de-magnification. Magnification is related to scaling up visuals or images to be able to see more detail, increasing resolution. Typically, magnification is achieved using optical instruments (magnifying glass, microscope, telescope, etc.), printing techniques, or digital processing (digital magnification). In all cases, the magnification of the image does not change the perspective of the image.
