Noise can be summarized as the visible effects of an electronic error (or interference) in the final image from a digital camera. Noise is a function of how well the sensor (CCD/CMOS) and digital signal processing systems inside the digital…

Digital information is a system that represents data using binary digits, known as “bits.” These bits have two possible states: “0” and “1,” or “on” and “off,” which makes them easily processed by electronic systems. Analog information, on the other…

The perceived color of an object is affected by the color of the lighting under which it is viewed. The human brain is capable of detecting and compensating for such changes in perceived color. As a result, a white object…

A rendering intent is a set of instructions that guide the conversion of digital color data to the color space of a specific output device, such as a printer or a display. The absolute colorimetric rendering intent is one of…

Each pixel in an image can represent a range of grayscale values. An 8-bit per color channel image, also known as a 24-bit image, can display up to 16.7 million distinct colors (8 bits x 3 color channels = 24…

Chromatic aberration is an optical defect that occurs in a lens, causing different wavelengths or colors of light to be focused at different distances from the lens. This results in the appearance of color fringes or halos along the edges…
