The calotype is the early paper negative process patented in 1841 that made multiple positive prints from one camera exposure possible.
A camera color profile in photography translates a sensor's raw RGB values into standard colors, defining hue, saturation and tone after white…
A camera obscura is a darkened chamber in which light passing through a small opening projects an inverted image, the optical ancestor…
A CCD is an image sensor that moves collected charge across the chip to a single output amplifier, valued in photography for…
Chromatic aberration is a lens fault in which different wavelengths focus at different points, causing colored fringes along high-contrast edges.
Chromatic noise in photography is random color variation between pixels, seen as colored speckles or blotches in shadows and high-ISO images.
CMOS is the image sensor technology in most digital cameras, converting light to charge and reading it out through transistors and converters…
A color cast is an unwanted tint that shifts the colors of a whole photograph toward one hue, usually caused by light…
A color checker is a reference chart of precisely measured color and gray patches used to set white balance and build accurate…
Color gamut in photography is the range of colors a color space, display or printer can reproduce, which limits how saturated images…
Color temperature in photography describes how warm or cool a light source appears, measured in kelvin along the black-body curve.
Contrast detection AF is an autofocus method that moves the lens until image contrast on the sensor peaks, giving precise but slower…
Crop factor is the ratio between the full frame diagonal and a smaller sensor diagonal, used to compare angle of view across…
