Audacity
In the car culture of Southern California some car owners will go to any length to keep their pride and joy from acquiring any scratches or dings.
The f/11 setting helped keep the car and the signs in focus, I then added a layer in Photoshop with a Gaussian blur, then masked out the car and the signs to create a bokeh effect after the fact. Silver Efex Pro 2 was used to convert to black and white, and then to selectively reveal the color in the signs.
