Photoshop Creative

Ctrl J to copy.
Ctrl+Shift+U to remove color.
Ctrl J to copy the black and white layer. On this layer Ctrl I to invert.
Change the blend mode on inverted layer to Color Dodge.
Go to Filter, Other, Minimum. I used 4 pixels or so.

Now go back to original layer( the one with color).
Ctrl J to copy.
Drag that layer to the top and reduce the opacity.
Merge the top three layers so you're left with two layers.
Ctrl J to copy.
Go to Filter, Artistic, Poster Edges.
Play with the opacity until you get something you like.
