Sharpness
The Pike color models are equipped with a two step sharpness control, applying
a discreet horizontal high pass in the Y channel as shown in the next three line
profiles.
Sharpness 0, 1 and 2 is calculated with the following scheme:
Sharpness value
0 0 1 0
1 -0.25 +1.5 -0.25
2 -0.5 2 -0.5

Note

Sharpness does not show any effect on Pike color models in the
Raw8 and Raw16 format, because color processing is put off in
all Raw formats.
