  1. Canon 20D vs. Film ISO400

  2. Canon 20D vs. Film ISO1600

  3. Fuji F30 44.4mm2 7.27 μm2/pixel Canon G7 38.2mm2 3.82 μm2/pixel Canon Rebel XT 328.56mm2 41.07 μm2/pixel Panasonic FZ50 38.2mm2 3.78 μm2/pixel Sony W80 24.7mm2 3.42 μm2/pixel

  4. Random Noise Fluctuation in light input (random distribution of photons) Chrominance Noise Variation in color Luminance Noise Variation in brightness

  5. 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
