Sharpen
While the Blur controls also let you apply sharpening simply by lowering, rather than raising, the
Radius sliders, the actual Sharpen mode provides additional controls specifically for tailoring
sharpening operations.
Sharpening with Coring Softness and Level
 Radius: This is the primary control for adding blur or sharpening. The default value of
0.50 results in no effect being applied to the image. Raising the radius slider increases
blur, to a maximum value of 1.00. Lowering the radius increases sharpness, with a
minimum value of 0.00 providing maximum sharpness.
 H/V Ratio: Lets you add directionality to the current operation. At the default value of
0.50, the image is affected in both the horizontal and vertical directions equally. Raising
H/V Ratio makes the effect increasingly directional along the horizontal axis, while
lowering makes the effect increasingly directional along the vertical axis.
 Scaling: Multiplies the amount of scaling being applied by the Radius control for
sharpening operations. The scaling parameter has no effect if Radius is set to 0.50 or
above for blur effects.
The Coring Softness and Level parameters work together to let you limit sharpening to only the
most detailed areas of the picture that would most benefit from it, based on a threshold of
image detail that you define using the Level and Softness parameters.
 Level: The first slider you should use. Raising this value sets the threshold at which
image detail is omitted from the sharpening operation. The default setting of 0 sets the
threshold low enough to sharpen the entire image. Raising Level gradually omits low-
detail areas of the image, which results in sharpening being restricted to well-defined
outlines.
 Coring Softness: After you’ve set the Level slider to an appropriate amount, raising
Coring Softness blends the border between parts of the image that are sharpened and
parts of the image that are left alone.
To adjust the Sharpening controls using the DaVinci control panel:
1 Press the VECTORS button on the T-bar panel, or the VECTORS soft key on the Center
panel’s main page.
2 On the Center panel, press the IMAGE MODE soft key repeatedly to cycle to the
RESOLVE IMAGE SHARPENING controls.
3 Use the SHARP AMOUNT, SCALING, LEVELS, and SOFTNESS knobs to create the
desired sharpening effect.
4 When you’re finished, press the PRIMARIES soft key to return to the Center panel’s
main page.
