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.
1G No gain (default)
2G Medium gain
4G Heavy gain
8G Maximum gain
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).
