Using the focus tools
The focus tools consist of the blur tool and the sharpen tool. The blur tool softens hard
edges or areas in an image to reduce detail. The sharpen tool focuses soft edges to
increase clarity or focus. For information on other ways to adjust sharpness, see
“Sharp-
ening images” on page 155 and “Improving performance with filters” on page 324 .
To use the blur or sharpen tool:
1 Select the blur tool or sharpen tool .
2 Do the following in the options bar:
•
Choose a brush and set brush options. (See “Working with brushes” on page 228 .)
•
Specify a blending mode and strength. (See “Setting options for painting and editing
tools” on page 241 .)
•
Select Use All Layers to blur or sharpen using data from all visible layers. If this is
deselected, the tool uses data from only the active layer.
3 Drag over the part of the image you want to blur or sharpen.
Using the toning tools
The toning tools consist of the dodge tool and the burn tool. Used to lighten or darken
areas of the image, the dodge and burn tools are based on a traditional photographer’s
technique for regulating exposure on specific areas of a print. Photographers hold back
light to lighten an area on the print (dodging) or increase the exposure to darken areas on
a print (burning).
To use the dodge or burn tool:
1 Select the dodge tool or burn tool .
2 Do the following in the options bar:
•
Choose a brush and set brush options. (See “Working with brushes” on page 228 .)
•
Select what to change in the image: Midtones to change the middle range of grays;
Shadows to change the dark areas; Highlights to change the light areas.
•
Specify the exposure for the tool. (See “Specifying opacity, flow, strength, or exposure”
on page 243 .)
•
(Photoshop) Click the airbrush button to use the brush as an airbrush. Alternately,
select the Airbrush option in the Brushes palette. (See “Creating airbrush effects
(Photoshop)” on page 239 .)

Using the sponge tool
The sponge tool subtly changes the color saturation of an area. In Grayscale mode, the
tool increases or decreases contrast by moving gray levels away from or toward the
middle gray.
