Lens Description
Brighten Lets you brighten and darken object areas and set the rate of the
brightness and darkness
Color add Lets you simulate an additive light model. The colors of the objects
beneath the lens are added to the color of the lens as if you were
mixing colors of light. You can choose the color and the amount of
color you want to add.
Color limit Lets you view an object area with only black and the lens color
showing through. For example, if you place a green color limit lens
over a bitmap, all colors except green and black are filtered out in
the lens area.
Custom color map Lets you change all the colors of the object area beneath the lens
to a color ranging between two colors you specify. You can choose
the range’s start and end colors and the progression between the
two colors. The progression can follow a direct, forward, or reverse
route through the color spectrum.
Fish eye Lets you distort, magnify, or shrink the objects beneath the lens,
according to the percentage value you specify
Heat map Lets you create the effect of an infrared image by mimicking the
heat levels of colors in object areas beneath the lens
Invert Lets you change the colors beneath the lens to their
complementary CMYK colors. Complementary colors are colors that
are opposite each other on the color wheel.
Magnify Lets you magnify an area on an object by an amount that you
specify. The magnify lens overrides the original object’s fill, making
the object look transparent.
Tinted grayscale Lets you change the colors of object areas beneath the lens to
their grayscale equivalents. Tinted grayscale lenses are particularly
effective for creating sepia-tone effects.
Transparency Lets you make an object look like a piece of tinted film or colored
glass
Wireframe Lets you display the object area beneath the lens with the outline or
fill color of your choice. For example, if you set red for the outline
and blue for the fill, all areas beneath the lens appear to have red
outlines and blue fills.
