ADOBE PHOTOSHOP ELEMENTS

individual pixels in a selection. Within a specified 
radius, the Maximum and Minimum filters 
replace the current pixel’s brightness value with 
the greatest or least brightness value of the 
surrounding pixels.

Moves a selection a specified amount 

horizontally to the right or vertically down, 
leaving an empty space at the selection’s original 
location. Depending on the size of the selection, 
you can fill the empty area with a transparent 
background, with the edge pixels, or with pixels 
from the right or bottom edges of an image. 
(See “Defining undistorted areas” on page 191.)

The Lighting Effects filter lets you produce myriad 
lighting effects on RGB images. You can also use 
textures from grayscale files (called bump maps) to 
produce 3D-like effects and save your own styles 
for use in other images.

The Lighting Effects filter allows adjustment of 
light styles, light types, light properties, and a 
texture channel.

Choose Filter > Render > Lighting Effects, 

or use the Filters palette to apply the Lighting 
Effects filter. 

For Style, choose a style. (See “Choosing a 

For Light Type, choose a type from the menu. 

If you’re using multiple lights, select and deselect 
On to turn individual lights on and off. (See 
“Choosing a Lighting Effects type” on page 208.)

To change the color of the light, click the color 

box in the Light Type section of the dialog box. 

The color picker chosen in the General Preferences 
dialog box opens. For information on choosing a 
color picker, see “Using the Adobe Color Picker” 
on page 77, or “Using other color pickers” on 
page 79.

To set light properties, drag the corresponding 

slider for the following options:

Gloss determines how much the surface reflects 

light (as on the surface of a piece of photographic 
paper) from Matte (low reflectance) to Shiny 
(high reflectance). 

Material determines whether the light or the 

object on which the light is cast reflects more light. 
Plastic reflects the light’s color, Metallic reflects the 
object’s color.

Exposure increases the light (positive values) or 

decreases the light (negative values). A value of 0 
has no effect.

Ambience diffuses the light as if it were 

combined with other light in a room, such as 
sunlight or fluorescent light. Choose a value of 100 
to use only the light source, or a value of –100 to 
diffuse the light source. To change the color of the 
ambient light, click the color box and use the color 
picker that appears.
