Defringe Layers in Photoshop Elements 10
A telltale sign of haphazardly composited images is selections with fringe — the unattractive kind that consists of background pixels that surround the edges of your selections. Inevitably, when you move or paste a selection, some background pixels are bound to go along for the ride. These pixels are referred to as a fringe or halo.
Luckily, the Defringe command replaces the color of the fringe pixels with the colors of neighboring pixels that don’t contain the background color. In the example, the toy boat is plucked out of a white studio background and placed on an image of water.
Some of the background pixels were included in the selection and appear as a white fringe. When you apply the Defringe command, those white fringe pixels are changed to colors of nearby pixels, such as blue or red.
Follow these steps to defringe your selection:
In Full Photo Edit or Quick Photo Edit mode, copy and paste a selection onto a new or existing layer, or drag and drop a selection onto a new document.
Choose Enhance→Adjust Color→Defringe Layer.
The Defringe dialog box appears.
Enter a value for the number of pixels that needs to be converted.
Try entering 1 or 2 first to see whether that does the trick. If not, you may need to enter a slightly higher value.
Click OK to accept the value and close the dialog box.
