You can smear, smudge, or blend the paint in an image. Smearing produces a similar effect to dragging across wet paint. Smudging has the same effect as rubbing across a pastel drawing. Blending softens the transition between colors or hard edges. You can smear, smudge, or blend the colors in an entire image or in an editable area you define. For more information about defining an editable area, see “Working with masks.”
The Smear tool was used to alter the shapes surrounding the star.
