3 Enter a value in the Size text box to determine the length of any side of the object's
base, from 2 to 255 pixels.
4 Enter a value in the Depth text box to indicate how far the tallest object appears to
protrude from the screen, from 0 to 255.
5 Choose a depth option:
Random to give each block or pyramid an arbitrary depth.
•
Level-based to make each object's depth correspond to its brightness—bright
•
protrudes more than dark.
6 Select Mask Incomplete Blocks to hide any object extending beyond the selection.
Find Edges (Photoshop) Identifies the areas of the image with significant transitions and
emphasizes the edges. Like the Trace Counter filter, Find Edges outlines the edges of an
image with dark lines against a white background and is useful for creating a border
around an image.
Glowing Edges Identifies the edges of color and adds a neon-like glow to them.
Solarize Blends a negative and a positive image—similar to exposing a photographic
print briefly to light during development.
Tiles Breaks up an image into a series of tiles, off-setting the selection from its original
position. You can choose one of the following to fill the area between the tiles: the
background color, the foreground color, a reverse version of the image, or an unaltered
version of the image, which puts the tiled version on top of the original and reveals part of
the original image underneath the tiled edges.
Trace Contour (Photoshop) Finds the transitions of major brightness areas and thinly
outlines them for each color channel for an effect similar to the lines in a contour map.
To use the Trace Contour filter:
1 Choose Filter > Stylize > Trace Contour.
2 Choose an Edge option to outline areas in the selection: Lower outlines where the color
values of pixels fall below the specified level, and Upper outlines where the color values
fall above.
3 Enter a threshold (Level) for evaluating color values (tonal level), from 0 to 255.
Experiment to see what values bring out the best detail in the image.
Use the Info palette in Grayscale mode to identify a color value that you want traced.
Then enter the value in the Level text box. (See
page 32.)
Wind Creates tiny horizontal lines in the image to simulate a wind effect. Methods
include Wind; Blast, for a more dramatic wind effect; and Stagger, which offsets the wind
lines in the image.
