Sometimes a print or online project needs an outline-type silhouette instead of an actual photo, in order to illustrate a project. By using the Threshold tool and the Gradient tool, we can make a few unique effects to complement a print of online design.

Silhouettes and Gradients Photoshop Tutorial
Step 1
Open up an image that has a clearly-defined outline that differentiates elements within the photo. Download one of these two support files to follow along with these examples, which are in the public domain.

Step 2
Go to Image>Adjustments>Threshold.

Step 3
Drag the arrow so that the subjects in the photo and other areas we want to be visible are black. For the helicopter photo, place the arrow between the two areas of pixels. For this example, I set it to 90. Press OK.

Step 4
We need to make the Background layer a normal layer in order to remove the white pixels. Double-click the Background layer and click OK to name it its default name, Layer 0.

Step 5
There are many ways to select the white pixels, but let’s just use the simple Magic Wand tool.

Step 6
Set the Tolerance to 0 and make sure Contiguous is unchecked. This will ensure that the white pixels that are not adjacent to, or contiguous to, the white area of pixels that we click will still be selected.

Step 7
Click somewhere in the white pixels and press Backspace to delete them

Step 8
Next, click on the New Layer icon on the bottom of the Layers palette to create a new layer. Click-and-drag this layer so it’s below Layer 0.

Step 9
With the Marquee Selection tool, click somewhere on the image to de-select the pixels, if they are still selected. Select the Gradient tool.

Step 10
With Layer 1 selected in the Layers palette, and the Gradient tool selected, double-click on the Foreground Color selector near the bottom of the toolbar. Set it to White. Double-click the Background Color selector and set it to an orange hue. I set mine to #ffa800. This sets the color of each side of the gradient.

Step 11
Click-and-drag from the top of the image to about a fourth from the bottom. Press Shift to maintain a straight vertical line.

Step 12
It should look something like this.

Step 13
For another example, repeat steps 1-11 but with the photo of the soldiers. But before going to step 11, set the gradient type to Radial.

Step 14
Switch the orange and white by clicking double-sided arrow near the bottom of the toolbar. Click-and-drag from behind the second soldier to simulate an area of sunshine. Crop out the extra black pixels we don’t need.

Now we can use this technique to create illustration-like outlines and silhouettes for print and online designs.

Can you tell me how I show 2 photos over eachother so that 1 photo has a transparancy from top to bottom from 100 to 0, and the other photo the opposite way?
TIA, kind regards,
Cor

i think you should select the background layer first before using the gradient tool.. im not so sure about it, but i hope it works..

Better way: use the pen tool to trace your objects, and then fill them with a solid color.

The problem is that the Threshold filter leaves the picture line a little jagged and noisy, to avoid this you can simply start with a higher resolution picture, go through your steps to number 11, downsize the picture using one of the bicubic algorithms (photoshop CS3 has 3 different flavors, CS2 just 1, if i remember right) and then complete your tutorial. The silhouette lines will be much smoother now.
