The Size slider naturally adjusts the size of the brush stroke, while the Hardness slider controls the feathering of the brush edge - the amount is displayed on-screen between the size of the outer and inner rings of the brush or the eraser cursor. Drag the slider to the left (towards 0) to increase feathering or to the right to decrease the effect. When a hard edge is required without any feathering, select a value of 100 (%). This is the maximum hardness that can be applied.
You can switch quickly between the Brush and Erase tools by using the keyboard shortcuts (B) and (E) respectively. The Brush and Erase settings may be linked and synchronized so that one stroke erases the other using the same Size and Hardness values.
- Select the Brush by clicking on the Brush icon in the Layers tool or from the Cursor toolbar.
- Click on the Brush Settings button (slider icon) or press Ctrl/Right-click anywhere in the Viewer for quick access. The Brush Settings panel opens.
- To adjust the size and feathering (hardness) of the brush adjust the two sliders;
- Size - Drag the slider to the right to increase while viewing the effect on the Brush/Eraser cursor in the Viewer. Alternatively, press [ or ] keys to decrease or increase the Brush size respectively, or enter text directly in the value box, or select and use the arrow keys or Shift-arrow keys to values by fixed values.
- Hardness - Drag the slider to the right to increase hardness while viewing the effect on the Brush/Eraser cursor in the Viewer. Alternatively, press Shift+[ or Shift+] keys to decrease or increase respectively.
