Using Filters
Sketch filters Add texture to images, often for a
3-D effect. The filters also are useful for creating a
fine-arts or hand-drawn look. Many of the Sketch
filters use the foreground and background color as
they redraw the image. For information on the
Conté Crayon filter, see “Using texture and glass
surface controls” on page 304.
For a truer effect when using the Conté
Crayon filter, change the foreground color
to one of the common Conté Crayon colors
(black, sepia, sanguine) before applying the
filter.
Stylize filters Produce a painted or impression-
istic effect on a selection by displacing pixels and
by finding and heightening contrast in an image.
After using filters like Find Edges and Trace
Contour that highlight edges, you can apply the
Invert command to outline the edges of a color
image with colored lines or to outline the edges of
a grayscale image with white lines. (See “Using the
Invert command” on page 130.)
Texture filters Give images the appearance of
depth or substance, or to add an organic look.
(See “Using texture and glass surface controls” on
page 304.)
Video filters Include the NTSC (National
Television Standards Committee) Colors filter,
which restricts the gamut of colors to those
acceptable for television reproduction, and the
De-Interlace filter, which smooths moving images
captured on video.
Other filters Let you create your own filters, use
filters to modify masks, offset a selection within an
image, and make quick color adjustments. For
more on the Offset filter, see “Defining undis-
torted areas” on page 304.
For more information on the Custom filter,
see the online help.
Digimarc filters Embed a digital watermark into an
image to store copyright information.
For more information on Digimarc filters,
