Transparency (graphic) GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats. The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible.
Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two or more images or video streams together based on colour hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion ...
Schlieren photography is used to visualise the flows of the media, which are themselves transparent (hence, their movement cannot be seen directly), but form refractive index gradients, which become visible in schlieren images either as shades of grey or even in colour. Refractive index gradients can be caused either by changes of temperature ...
Backscatter (photography) The backscatter of the camera's flash by motes of dust causes unfocused orb-shaped photographic artifacts. In photography, backscatter (also called near-camera reflection[1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of ...
Image file format. An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy ...
A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. [ 7 ] PNG files have the ".png" file extension and the "image/png" MIME media type. [ 8 ] PNG was published as an informational RFC 2083 in March 1997 and ...
Moiré pattern appearing on scaled camera captures of LCD screen Moiré pattern of double layered shading net In mathematics, physics, and art, moiré patterns ( UK : / ˈ m w ɑː r eɪ / MWAH -ray , US : / m w ɑː ˈ r eɪ / mwah- RAY , [ 1 ] French: [mwaʁe] ⓘ ) or moiré fringes [ 2 ] are large-scale interference patterns that can be ...
Multiplane camera. The multiplane camera is a motion-picture camera that was used in the traditional animation process that moves a number of pieces of artwork past the camera at various speeds and at various distances from one another. This creates a sense of parallax or depth.
