Nik Sharpener and Nik Color Efex were developed by Nik Multimedia Inc. [1] in the 1990s as digital photo filters that could be used in Photoshop or as standalone applications. Some years later, in 2003, Dfine 1.0 , a denoising application and plugin was added to the list of products on offer.
Photoshop plugins (or plug-ins) are add-on programs aimed at providing additional image effects or performing tasks that are impossible or hard to fulfill using Adobe Photoshop alone. Plugins can be opened from within Photoshop and several other image editing programs (compatible with the appropriate Adobe specifications) and act like mini ...

An excellent example is the photograph Schweitzer with lamp at his desk by W. Eugene Smith, [2] from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to produce, in order to reproduce the tonal range of the scene, which ranges from a bright lamp (relative ...
Most graphics editing programs, such as Adobe Photoshop and GIMP, allow users to modify the basic blend modes, for example by applying different levels of opacity to the top "layer". The top "layer" is not necessarily a layer in the application; it may be applied with a painting or editing tool.
Bloom in digital cameras is caused by an overflow of charge in the photodiodes, which are the light-sensitive elements in the camera's image sensor. [3] When a photodiode is exposed to a very bright light source, the accumulated charge can spill over into adjacent pixels, creating a halo effect. This is known as "charge bleeding."
Lighting determines exposure and can be used to create effects such as low-key and high-key lighting, both of which involve the contrast between darker and lighter elements in a scene. [2] Lighting is especially important for monochrome photography, where there is limited to no color information, and exclusively includes the interplay of ...
Since the focal length of the lens varies with the color of the light different colors of light are brought to focus at different distances from the lens or with different levels of magnification. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image.
