If you're talking about the K channel in CMYK, that's true; but grayscale<br>
|
|
images usually have the same polarity as RGB: 0 = black, maximal value = white.<br>
|
|
<p>
|
|
The point about multiplying by 17 instead of 16 when going from 12 bit to<br>
|
|
16 bit is that it preserves the maximal value for white if the frontend uses<br>
|
|
all 16 up-sampled bits.<br>
|
