The Clone Brush Tool paints samples from one part of an image onto another. It's useful for removing defects, general photo retouching and duplicating parts of an image. Like all brush tools, it is pressure sensitive to create natural looking strokes when using a pressure-sensitive device.
Settings
The following settings can be adjusted using vertical tool sliders:
Opacity/Scale/Accumulation toggle—how see-through the brush is, the sample setting (between 1% and 1000%) or the extent of deviation in the opacity or visibility of the stroke as it is painted, respectively. Tap to toggle the setting, then slide up or down to set the value.
Flow/Hardness toggle—how fast the brush effect is applied (1% is very slow, 100% is immediate) or how hard edged the brush is, respectively.
Rotation/Width toggle—Sets the degree of rotation applied to the sample or controls the width of the stroke, respectively. Slide up or down to set the width.
The following settings can be adjusted from the context toolbar:
More—tap to display the Brushes dialog to access advanced brush settings.
Force Pressure—toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
Aligned—when selected (default), the origin of the sample remains a fixed distance from the pointer. If this option is off, the origin of the sample always returns to the sample location defined initially.
Flip—allows for horizontal and vertical flipping of the resulting clone relative to the sampled area. Choose horizontal, vertical or both directions from a pop-up menu.
Blend Mode—changes how the applied pixels interact with existing pixels on a layer. Choose mode type from a pop-up menu.
Source—the source determines the layer(s) from which the pixels are sampled. Select from the pop-up menu.
The following on-screen modifiers options are available:
Continue / Constrain—when pressed, laid-down cloned areas are conjoined.
Set Source—sets the clone source as a key press as you continue cloning.
