## Definition

the act of making something look larger than it really is, usually using a tool like a lens or a computer program. It helps you see tiny details that are hard to spot with your eyes.

For teachers: the process of enlarging the apparent size of an object or image, typically through the use of optical instruments or digital software. Often refers to the ratio of the image size to the object size.

## Examples
