Magnification - Definition and Overview

Magnification is the process of enlarging something only in appearance, not physical size.

Optical magnification

• Typically magnification is related to scaling up visuals or images to be able to see more detail, increasing resolution, using optics, printing techniques, or digital processing. In all cases, the magnification of the image does not change the perspective of the image.

Other uses

• One can also magnify sounds (see amplification, volume).
• Magnification can also be used as a generalized term for increasing the detail or vividness of something: ideas, emotions, etc.
