I’m always looking for ways to take renderings that just aren’t working and turn them into something that can be used for portfolios or cover pages. This tutorial is about as simple as it gets in terms of difficulty and speed. In the example below, the initial image was a crap renderings right out of Kerkythea. Sketchup images will work too, just turn off the line work. The idea is to take the dead rendering and dilute it to the point that it becomes more artistic and abstract. These types of images are great for introductory pages and portfolios because text can take on a stronger hierarchical role with the rendering moving to the background. You will see that it only takes a few steps to get to what I think is a nice looking result.

2. In the “Posterize” dialogue box, set the levels to “2”. I think the look is better with a minimal number of levels, however, you can use as many levels as you want. You may have to adjust the brightness or contrast prior to this step to get the Posterize filter to read better.
6. In the “Hue/Saturation” dialogue box, first check “Colorize”. Next, move the “Lightness” slider to the left so that all of the pure white color is removed. Move the “Saturation” slider to the right to increase the color according to your preference. Finally, adjust the “Hue” to the color scheme you like. I have found it is much easier to get the style your are looking for by adjusting the sliders in the above order.
