Add your picture
• Duplicate layer
• Choose image>Adjustments>Shadow Highlight
Move the amount slider as high as it will go. The image
may look a little too bright in places but that doesn't
• Choose Filter>Stylize>Find Edges
• All the edges will now become outlined. The color has
gone a bit funky though. We'll fix that and finish the effect
in the next step.
• Choose Edit>Fade Find Edges (This option will only be
available at this point, if you do anything else between
Find Edges and Fade, you won't be able to do this)

the colors (Don't close the dialog yet)

with different colors (comic book effect)
Another option is to desaturate and color
Or, using Poster Edges
Photo Filter under Image can be used to apply a color
You can use the magic wand or lasso to cut them out
Play with the tolerance to make this easier
Sometimes if you duplicate the layer, simplify through a filter, and
then use that to cut out parts, that can make this process easier
Color, shading and lighting it what makes this work well
Watch out for edges
The KEY: Insert everyone in to a new scene,
and use curves to make the colors match.
Save as a JPEG and cut quality some also.
