Chromatic noise in photography is random color variation between pixels, seen as colored speckles or blotches in shadows and high-ISO images.
Dynamic range in photography is the span between the brightest and darkest tones a camera can record with detail, usually measured in stops.
Luminance noise in photography is random pixel-to-pixel variation in brightness that appears as monochrome grain, most visible in shadows and at high ISO.
Moiré in photography is a false wavy or colored pattern that appears when fine repeating detail interferes with the regular pixel grid of a camera sensor.
Read noise is the random electronic noise added when a camera sensor converts and reads out its signal, limiting shadow detail and dynamic range.
Sharpness in photography is the perceived clarity of detail and edges in an image, shaped by resolution, acutance, focus, motion and viewing size.
Shot noise is the random variation in the number of photons a camera sensor captures, the main source of noise in most photographs and a limit…
Signal-to-noise ratio in photography compares the useful image signal with random noise, determining how clean and detailed a digital photo looks.
