  2. Miniature faking - Wikipedia

    en.wikipedia.org/wiki/Miniature_faking

    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.

  3. Magnification - Wikipedia

    en.wikipedia.org/wiki/Magnification

    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 .

  4. Depth of field - Wikipedia

    en.wikipedia.org/wiki/Depth_of_field

    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 ...

  5. Image scaling - Wikipedia

    en.wikipedia.org/wiki/Image_scaling

    Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem. According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts. The image is ...

    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
