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.
To be viewed or printed, the output from a camera's image sensor has to be processed, that is, converted to a photographic rendering of the scene, and then stored in a standard raster graphics format such as JPEG. This processing, whether done in-camera or later in a raw-file converter, involves a number of operations, typically including: [30 ...
In photography, bokeh (/ ˈ b oʊ k ə / BOH-kə or / ˈ b oʊ k eɪ / BOH-kay; [1] Japanese:) is the aesthetic quality of the blur produced in out-of-focus parts of an image, whether foreground or background or both. It is created by using a wide aperture lens.
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.
Transparent displays embed the active matrix of the display in the field of view, which generally allows them to be more compact than combination-based systems. Broadly, there are two types of underlying transparent display technology, absorptive (chiefly LCDs) and emissive (chiefly electroluminescent, including LEDs and "high-field" emitters ...
Optical video recording technology, using a transparent disc, [6] was invented by David Paul Gregg and James Russell in 1963 (and patented in 1970 and 1990). [7] [8] The Gregg patents were purchased by MCA in 1968. By 1969, Philips had developed a videodisc in reflective mode, which has advantages over the transparent mode. MCA and Philips then ...
