This tutorial will show you a quick way to use photoshop to create a trendy, effective, two-tone silhouette effect. Once you have mastered creating the two-tone silhouette effect you can experiment with different colours and filters. 

1.) First you need to start with the photo you want to apply the effect to, any photograph will work well with this effect as long as it is of a good quality. 

2.) You then need to duplicate your layer, this isn’t essential but it helps if you make a mistake when completing the design, then desaturate your duplicated layer, you do this by using Image > Adjust > Desaturate. 

3.) Now go to Filter > Artistic > Cutout and use settings similar to the following:

Number of Levels: 2

Edge Simplicity: 3/4

Edge Fidelity: 3

4.) The next step is to go to Image > Adjustments > Levels to bring up the Levels Dialog Box. Drag your sliders very close to each other, until your image is only black and white.

5.) Your image will probably have some pretty jagged edges. To fix this go to Filter > Blur > Gaussian Blur. Enter a value of around 2.0 pixels, or whichever makes your edges look smoothed.

6.) Bring up the Curves Dialog Box by going to Image > Adjustments > Curves. Adjust the curves so the edge blurriness is gone, but there is still no jagged edges. You could get a little more advanced with this by masking your subject out (cutting out) first, then running through the steps, this could give you the option to have a coloured background etc.
