Shadow Noise

	Shadow Noise {{main, Image noise Shadow noise or luminescence noise is an effect that digital lightening has on an image, specifically on the darker, or shadowed areas of the image. Brightening the image, especially in underexposed photos, brings out the "shadow noise" in such areas. Noise in digital photography is the analog to film photography's grain, or visible distortion that appears on an image. However, film grain tends to be less noticeable than noise, which can appear as distorted colors or artifacts on an image. A suitable analogy would be when a television begins to "snow" or experience "white noise", when static begins to appear on the screen, distorting or obscuring the image. Correction There are methods to correct shadow noise. Professional digital editing software like Photoshop have the capability to eliminate some amount of noise, while other software, such aBand Aideor Noise Ninja Noise Ninja is a proprietary noise reduction application and Photoshop plugin which attempts ...

picture info	Photoshop Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc. for Windows and macOS. It was originally created in 1988 by Thomas and John Knoll. Since then, the software has become the industry standard not only in raster graphics editing, but in digital art as a whole. The software's name is often colloquially used as a verb (e.g. "to photoshop an image", "photoshopping", and "photoshop contest") although Adobe discourages such use. Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models including RGB, CMYK, CIELAB, spot color, and duotone. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by plug-ins; programs developed and distributed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Science Of Photography The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly. Optics Camera obscura The fundamental technology of most photography, whether digital or analog, is the camera obscura effect and its ability to transform of a three dimensional scene into a two dimensional image. At its most basic, a camera obscura consists of a darkened box, with a very small hole in one side, which projects an image from the outside world onto the opposite side. This form is often referred to as a pinhole camera. When aided by a lens, the hole in the camera doesn't have to be tiny to create a sharp and distinct image, and the exposure time can be decreased, which allows cameras to be handheld. Lenses A photographic lens is usually composed of several lens elements, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
