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.

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 recommended. 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).
