This is a quick way to use photoshop to create that semi-trendy, two-tone silhouette effect.
Obviously start with the photo you want to apply the effect to. I used another photo from PhotoSpin (PhotoSpin #1410017).
two_tone1
Start by duplicating your layer [Ctrl + J]. You don’t HAVE to duplicate the layer, but it helps if you make a mistake.
Desaturate your duplicated layer by pressing [Ctrl + Shift + U].

Now go to [Filter > Artistic > Cutout]. Use settings similar to the following:
  • Number of Levels: 2
  • Edge Simplicity: 3 or 4
  • Edge Fidelity: 3

You should get an effect similar to this:
two_tone4
Press [Ctrl + L] to bring up the Levels Dialog. Drag your sliders very close to each other, until your image is only black and white.
two_tone5
Your image will probably have some pretty jagged edges.
two_tone6
To fix this, go under [Filter > Blur > Gaussian Blur]. Enter a value of around 2.0 pixels, or whatever looks like your edges are smoothed.
two_tone7
Bring up the Curves Dialog by pressing [Ctrl + M]. Adjust your Curves so the edge blurriness is gone, but there is still no jagged-ness. (Is jagged-ness a word?).
two_tone8
And that should be it.
two_tone9
You could get a little more advanced with this by masking your subject out (cutting out) first, then running through the steps.
