Blur

The Blur tool reduces image sharpness by decreasing color contrast between neighboring pixels. To quickly access this tool and switch between the Blur, Sharpen, and Smudge tools press R.

The tool's parameters will be shown in a floating box over an image (by right-clicking the mouse) and also in the Settings Panel.

To change the value of a parameter, enter a numerical value in the parameter's field and press Enter (Mac: Return) or adjust the slider.

• Size (1-200). Blur brush size (in pixels).
• Hardness (0-100). The width of the tool's outer edge, where the image is partially blurred. The higher the value, the larger the area within the brush where blur is applied completely.

  Hardness = 10%	Hardness = 80%

• Radius (0.1-5.0). Intensity of the effect on an image. This parameter specifies the area where points are searched for blurring: at higher values the blurring radius is larger.

  Radius = 1.5	Radius = 4.0

To blur the image along a straight line, left-click to choose a starting point, then, while pressing Shift, move the cursor to where the end point will be and left-click, then release Shift. If Shift is not released, a new line will be drawn to each point where the mouse is clicked.
