  2. Cesia (visual appearance) - Wikipedia

    en.wikipedia.org/wiki/Cesia_(visual_appearance)

    This is the same kind of phenomenon that Richard S. Hunter (1969) calls "geometric attributes of appearance". [1] The advantage is that the concept of cesia encompasses all the involved aspects in a single word, and that all cesias have been organized in a three-dimensional order system according to three axes of variation, similar to color order systems or color models.

  3. Opacity - Wikipedia

    en.wikipedia.org/wiki/Opacity

    An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass through). When light strikes an interface between two substances, in general, some may be reflected, some absorbed, some scattered, and the rest transmitted (also see refraction ).

  4. Transparency and translucency - Wikipedia

    en.wikipedia.org/wiki/Transparency_and_translucency

    Large laser elements made from transparent ceramics can be produced at a relatively low cost. These components are free of internal stress or intrinsic birefringence, and allow relatively large doping levels or optimized custom-designed doping profiles. This makes ceramic laser elements particularly important for high-energy lasers.

  5. Transparency (graphic) - Wikipedia

    en.wikipedia.org/wiki/Transparency_(graphic)

    This image has partial transparency (254 possible levels of transparency between fully transparent and fully opaque). It can be transparent against any background despite being anti-aliased. Some image formats, such as PNG and TIFF, also allow partial transparency through an alpha channel, which solves the edge limitation problem.

  6. Colonial morphology - Wikipedia

    en.wikipedia.org/wiki/Colonial_morphology

    The opacity of a microbial colony can be described as transparent, translucent, or opaque. Staphylococci are usually opaque, [1]: 167–8 while many Streptococcus species are translucent. [4]: 188 The overall shape of the colony may be characterized as circular, irregular, or punctiform (like pinpoints). The vertical growth or elevation of the ...

  7. Glass-ceramic - Wikipedia

    en.wikipedia.org/wiki/Glass-ceramic

    It can be made nearly transparent (15–20% loss in a typical cooktop) for radiation in the infrared wavelengths. In the visible range glass-ceramics can be transparent, translucent or opaque and even colored by coloring agents. However, glass-ceramic is not totally unbreakable.

  8. Overhead projector - Wikipedia

    en.wikipedia.org/wiki/Overhead_projector

    The opaque projector, or episcope is a device which displays opaque materials by shining a bright lamp onto the object from above. The episcope must be distinguished from the diascope, which is a projector used for projecting images of transparent objects (such as films or slides), and from the epidiascope, which is capable of projecting images ...

  9. Photogram - Wikipedia

    en.wikipedia.org/wiki/Photogram

    A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used.
