Real Torn Paper Edges for Photoshop

Torn Paper Edges, originally uploaded by jfrancis.

Real (not simulated) Torn Paper Edges, originally uploaded by jfrancis.

Some torn blue paper with a ragged white edge scanned against black.

There should be enough value and chroma difference to separate the blue from the white, and enough contrast value difference to separate the white from the 'black'

The real thing. Not simulated in Photoshop.

Paper is plain blue wrapping paper for sale at Target.
