Abstract:

Working in your new layer, and on the item you wish to keep in focus, find a starting point, click the mouse once and begin slowing tracing around the object. Once it has been entirely traced, return to your starting point and double-click to select your object. Under the SELECT menu choose INVERSE. Then under the FILTER menu choose BLUR » GAUSSIAN BLUR. When the Gaussian Blur window appears, use the radius slider bar to choose the amount of pixels to blur. I chose 4.5 for my example. When you are satisfied with the preview, click OK.
