Image cloning and sampling 163
Performing offset sampling
Offset sampling, also known as “point-to-point cloning,” lets you sample an area of an
image and then reuse it elsewhere within the document, or in separate document.
Sampling is a useful technique for retouching photographs.
To perform offset sampling, you must set a sampling reference point and then set
destination reference points. Sampling reference points specify the area of the document
that you want to reuse, or clone. Destination reference points determine the area where
you want the sampled image to appear. To identify which area of the source document
you are sampling, a crosshair cursor appears.
The green dot (left) represents the sampling reference point. The red dot (right)
represents the destination point.
It is important to note that the sampling reference point, also known as the source, is
not treated as a clone source. The sampled area does not display in the Clone Source
panel.
To perform offset sampling within a document
1 Click the Rubber Stamp tool in the toolbox.
If you want to adjust the size of the sampled area, type a value in the Size box, or
adjust the slider on the property bar.
2 Hold down Option (Mac OS) or Alt (Windows), and click to set the source
reference point.
A green marker appears on the image, indicating the reference point for the source
image.
3 Hold down Option + Shift (Mac OS) or Alt + Shift (Windows), and click to set
the destination reference point.
4 Apply brushstrokes to the destination area to reveal the sampled area.
