The process I used with these photos was by using different highlights/tones in photoshop and adding either a tint or lightness/darkness to flow with the other pictures. I thought of my car as "my home" because I paid for it on my own, pay my own insurance/gas, and feel like it is the one thing that is mine and is different from everything else I have. Home is suppose to be a place that you can call yours, and my car is the sum of this in many different ways.
