Chrominance NoiseVariation in color
Luminance NoiseVariation in brightness
Random NoiseFluctuation in light input (random distribution of photons)
Fixed Pattern Noise-Consistently reproducible noise-Caused by electronics, sensor defects, heat-Manifested as “hot pixels” or luminance anomalies-Since noise is reproducible (non-random), easily fixed by dark frame subtraction
