Optical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number. Optical magnification is sometimes referred to as "power" (for example "10× power"), although this can lead to confusion with optical power .
A common technique for making an image of a full-size scene resemble an image of a miniature model is to have the image progressively blurred from the center to the top or bottom, simulating the blurring due to the limited DoF of a typical image of a miniature. The blurring can be accomplished either optically or with digital postprocessing.
One of the most important properties of microscope objectives is their magnification.The magnification typically ranges from 4× to 100×. It is combined with the magnification of the eyepiece to determine the overall magnification of the microscope; a 4× objective with a 10× eyepiece produces an image that is 40 times the size of the object.
The red object in the lower left is a scale bar indicating relative size. Approximately 10× micrograph of a doubled die on a coin, where the date was punched twice in the die used to strike the coin. A micrograph is an image, captured photographically or digitally, taken through a microscope or similar device to show a magnified image of
The image size is the same as the object size. (The magnification of a flat mirror is equal to one.) The law also implies that mirror images are parity inverted, which is perceived as a left-right inversion. Mirrors with curved surfaces can be modeled by ray tracing and using the law of reflection at each point on the surface.
Currency commonly exhibits the highest quality (smallest size) of microprint because it demands the highest level of counterfeiting deterrence. [5] For example, on the series 2004 United States $20 bill , microprint is hidden within the border in the lower left corner of the obverse (front) side, as well as the Twenty USA background.

Note that = is the transverse magnification which is the ratio of the lateral image size to the lateral subject size. [5] Image sensor size affects DOF in counterintuitive ways. Because the circle of confusion is directly tied to the sensor size, decreasing the size of the sensor while holding focal length and aperture constant will decrease ...
