    Does anybody happen to know the formula used to calculate the value of
    a pixel once a certain amount of Analog Gain (AG) is applied?

    Example: Scan at Master AG=0. The value of a pixel is R=100, G=100,
    B=100. What would be value of that pixel when at, say, Master AG=1?

    I assume the same formula would apply to individual RGB channels,
    right?
