ISO The ~ in digital photography refers to the overall digital camera chip sensitivity to light. In general, the smaller the ~ setting in digital photography the less light sensitive the sensor will be, and the higher the quality of the image will be. ~ or ASA is how sensitive your film or digital camera is to light.

GUIDE TO IMAGE SHARPENING Image sharpening is a powerful tool for emphasizing texture and drawing viewer focus. It's also required of any digital photo at some point — whether you're aware it's been applied or not. Digital camera sensors and lenses always blur an image to some degree, for example, and this requires correction.

Demosaicing From Wikipedia, the free encyclopedia. A demosaicing (also de-mosaicing, demosaicking or debayering) algorithm is a digital image process used to reconstruct a full color image from the incomplete color samples output from an image sensor overlaid with a color filter array (CFA). It is also known as CFA interpolation or color reconstruction.

What is a Colorimeter? Top 10 amazing movie makeup transformations. A colorimeter is a light-sensitive instrument that measures how much color is absorbed by an object or substance. It determines color based on the red, blue, and green components of light absorbed by the object or sample, much as the human eye does.

Understanding Lighting Ratios Lighting ratios in photography is something many people seem to find confusing, when in actual fact ratios are very simple to understand. Lighting ratios are simply the difference in output between your key light and your fill light. These two lights are the main players in providing your photo with the shadow and depth required to make it look dynamic and interesting – just remember that good lighting is about good shadows!

- 4) Dichromat (red/green color blind) simulation of the Daltonized image. Here, the algorithm has mapped changes in the reds and greens into slight changes in brightness and bluishness. The result is that when viewed by someone with color blindness, the different labelled structures in the cell are clearly visible.

Color temperature The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the radiation of some bl

Color photography The first color photograph made according to Maxwell's prescription, a set of three monochrome  color separations , was taken by Thomas Sutton in 1861 for use in illustrating a lecture on color by Maxwell, where it was shown in color by the triple projection method.nstant color film was introduced by Polaroid in 1963. Like Polaroid's contemporary instant black-and-white film, their first color product was a negative-positive peel-apart process which produced a unique print on paper. The negative could not be re-used and was discarded.
