This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
EDGE GENERATOR: Generates sharp or blurry edges and all different shapes & sizes. You can also make transparent edges. It also comes with 4 different modes.
MODES:
1. Creates a White or Black Edge with Photo
showing.
2. Turns your Photo into an edge, leaving white in the
middle.
3. Creates a White or Black Edge Mask that can be
used in other programs.
4. Creates a transparent Edge so your Photo looks
like a cutout. This mode only works if your
background is transparent in your Paint Program.
There is also a Vertical & Horizontal offset supplied in case you need to move your New Edge around the canvas to center your photo. Many presets supplied to get you started.
P.S. Would like to thank Ken for his Edges code to
make this filter possible.
