Sample with precision with the Magic Wand tool in Photoshop

When you use the Magic Wand tool you have the option to set the tolerance, which determines the range of pixels selected when you use the tool. But did you know that the tolerance setting for the Magic Wand tool can produce different results depending on how you have the Eyedropper tool’s Sample Size option set? This option determines the number of pixels both tools sample.

The more pixels you sample, the broader the range of color, and the more precise (or possibly imprecise)
the selection.

To change the sample size of the Magic Wand:

  1. Select the Eyedropper tool in the Tools panel.
  2. Choose Point Sample, 3 By 3 Average, or 5 By 5 Average from the Sample Size pop-up menu on the tool options bar. The default is Point Sample, but we recommend 3 By 3 because the odds are better that you’ll sample the target color and not a bit of dust.
  3. Select the Magic Wand tool in the Tools panel and create a new selection as usual.
