Using the Clone Stamp or Healing Brush tool, you can sample sources in the current document or any open document in Photoshop.
(Photoshop Extended) When cloning video or animation, you can set sampling points in the current frame you’re painting or sample sources in a different frame, even if the frame is in a different video layer or in a different open document.
You can set up to five different sampling sources at a time in the Clone Source palette. The Clone Source palette saves the sampling sources until you close the document.
To scale the sample source, enter a percentage
value for W (width) or H (height) or scrub W or H. The default is
to constrain proportions. To adjust the dimensions independently
or restore the constrain option, click the Maintain Aspect Ratio
button .
To rotate the sample source, enter a degree value
or scrub the Rotate The Clone Source icon .
To reset the sample source to its original size
and orientation, click the Reset Transformation button .
You can adjust the sample source overlay options to see the overlay and underlying images better when painting with the Clone Stamp and Healing Brush tools.
To hide the overlay while you apply the paint strokes, select Auto Hide.
To set the opacity of the overlay, enter a percentage value in the Opacity text box.
To set the appearance of the overlay, choose either the Normal, Darken, Lighten, or Difference blending mode from the pop‑up menu at the bottom of the Clone Source palette.
To invert the colors in the overlay, select Invert.
When using the Clone Stamp tool or Healing Brush tool, you can paint with the sampled source anywhere in the target image. The overlay options will help you visualize where you want to paint. However, if you need to paint in a very specific location relative to the sampling point, you can specify the x and y pixel offset.
