G - Gain
Gain is used in Manual Style only (2P). Like a volume control, the gain modifier
boosts the signal and multiplies the pixel value. As you increase the gain, the noise
in an image is also amplified.

Example:
W - Target White Value
Sets the target for the median grayscale value in the captured image. For capturing
close-up images of high contrast documents, a lower setting, such as 75, is recom-
mended. Higher settings result in longer exposure times and brighter images, but
if the setting is too high, the image may be overexposed. Target White Value is only
available when using Photo Style (1P).
