In this tutorial we will show you how to make advanced posterize effects on your photos. You can add this effect easily on digital or scanned photo.

Step 1.

Open one of your photos that you would like to posterize. I have used this photo:
The Eye

Step 2.

Press CTRL+A to select entire image, and press CTRL+C to copy it into clipboard. Open up new document in photoshop (File -> New -> OK). Now paste your image into newly opened document (CTRL+V). Double click into layers palette on “Layer 1” and change it’s name into “Pic-1” for easier reference later. Right-click “Pic-1” in layers palette and choose “Duplicate Layer”, name a new layer “Pic-1-gray”. Covert “Pic-1-gray” to gray by selecting Image -> Adjust -> Desaturate or press on keyboard SHIFT+CTRL+U.

Step 3.

Again duplicate “Pic-1-gray” and rename it to “2”. With “2” selected in layers palette, go to Filter -> Blur -> Smart Blur, with these settings: – Radius: 62 – Treshold: 96 And also choose: High Quality, Mode: Edge Only. Press Enter, and invert layer “2” by pressing CTRL+I on keyboard, or, alternatively go to Image -> Adjustments -> Invert.

Step 4.

Apply new blur effect, go to: Filter -> Blur -> Gaussian Blur, and use Radius: 1,5. Change Blending mode of “2” layer from “Normal” to “Hard Light”

Step 5.

Again duplicate gray layer “Pic-1-gray” (right-click on it and choose: duplicate…). Call the new layer “3”. Move it on top of other layers, as shown on Image 5.

With layer “3” selected in layers palette go to Filters -> Stylize -> Emboss. Enter the settings as shown on Image 6.

Also, change it’s blenging mode to “Hard Light”.

Step 6.

Again duplicate gray layer “Pic-1-gray” and rename it to “4”, and also move it on top of other layers again. Now apply a smart blur filter by choosing Filter -> Blur -> Smart Blur, and enter options as shown on Image 7.

Click OK. Invert the layer by pressing CTRL+I, and change the Blending Mode to Multiply and Opacity to 42%.

Step 7.

Now, once again duplicate that layer “Pic-1-gray” and drag it on top of other layers, and rename it to “5”. Apply the new filter on it, choose Filters -> Stylize -> Glowing Edges. Enter the settings as shown on Image 8.

Step 8.

Invert the layer “5” by pressing CTRL+I. Again change the blending mode of layer “5” to Multiply, and it’s opacity to 42%. Your image looks like this now:

Step 9.

Duplicate the layer “5” and put a filter on it, choose: Filter -> Blur -> Gaussian Blur. Enter “4” pixels in “Radius” field, and press Enter. Change layer’s “5 copy” blending mode to “Multiply” and it’s opacity to “100%”

Step 10.

Now all you have to do is colorize the photo. Choose that first layer on bottom of layers palette called “Pic-1”, select it, duplicate it, and rename it to “Pic-1-color”. Move that layer now on top of other layers, change it’s blending mode to “Hard Light” Duplicate that layer “Pic-1-color” and change it’s blending mode to “color”.

Step 11.

Final result is to much like a photo, so you might want to adjust it a bit, and tweak it. You will do that this way: Select “Pic-1-color” layer and go to Image -> Adjust -> Brightness/Contrast… Use settings as shown on Image 10.

And finally change opacity of layer “Pic-1-color copy” from 100% to around 50%. Final result will look something like this:
