How to Remove Blemishes from Your Digital Photos with Your Image Editor
If your digital image contains little marks (called artifacts) or your subject has an unsightly pimple, you can easily remove them with your image editor’s Brush or Pencil tool. Painting or drawing over artifacts removes them in a snap. To remove artifacts from your digital photo
1Click the tool that you want to use, like in this figure.
Use the Brush tool if you’re painting out a small dot or a tiny scratch. Go with the Pencil tool if you need a thin, precise line to get rid of the artifact in question.
2Set the size of the brush or pencil.
Select a size that’s roughly the same as the dot or scratch that you want to eliminate.
3Use the color-sampling tool to sip up the color from the surrounding unmarred pixels.
In Photoshop or Photoshop Elements, hold down the Alt (Option on a Mac) key to convert the Pencil or Brush tools temporarily into an eyedropper, as shown here.
