I know, I know, it can be caused by various factors, like high ISO, poor lighting conditions, long exposure time, heat. (not that I know why the last two cause noise)

But where does noise REALLY come from? What is noise? What does it have to do with photons and photosites?

    • EM interference from circuits on the sensor
    • heat and IR radiation from the sensor
    • imperfect ADC circuits
    • wave-like behaviour of light due to quantum effects
