How it Works
Crosshatch is a close cousin to Angled Strokes,
but with equal emphasis in each stroke direction.
The filter has the advantage over real artists’
cross-hatching, in that individual strokes are
composed of different colors because they
react to the underlying image.
|
|
Medium settings of Stroke
Length 25, Sharpness 10,
and Strength 2 produce an
over-strong result on this
small original.
|
|
Decreasing Stroke Length
to 10 and increasing
Sharpness to 20 produces an
interesting “knitted” effect.
|
|
With both Sharpness and
Strength at maximum, the
image is attacked on all
fronts, and is perhaps a little
too abstract to be useful.
|
|
At the same settings, the
target image shows how
this filter introduces spectral
noise effects in gray areas.
|
|
Using the Crosshatch Filter
This simple technique
applies Crosshatch in
increments, in conjunction
with Image > Adjustments >
Hue/Saturation.
|
|
Apply the Crosshatch
filter with Stroke Length 8,
Sharpness 3, and Strength 2.
|
|
Choose the Lasso tool and
set it to a soft feather of
about 20 pixels in the Tool
Options bar.
|
|
Select all (Ctrl/Cmd+A),
hold down the Alt/Option
key and use the Lasso tool to
subtract a small area from
the overall selection. When
the subtraction is complete,
hit Ctrl/Cmd+F to re-apply
the filter at the same settings.
|
|
With the selection still
active, go to Image >
Adjustments > Hue/
Saturation and reduce the
saturation of the selected
area. We took this initial
selection down to -24.
|
|
Once again, use the Lasso
tool with the Alt/Option key
depressed to further reduce
the selection. Reapply the
Crosshatch filter (Ctrl/
Cmd+F) then reduce
saturation as before.
|
|
Continue subtracting from
the selection, reapplying the
filter and desaturating until
only the last active area
remains. The effect is a
gradual increase in color up
to the focal point of the
image—the tiger’s face.
