I made a Photoshop file that allows you to use a curves layer. What you do is open your image in Photoshop and change to black and white (desaturate is the fastest way), then open this file I've provided (it's a .PSD) and drag the CURVES LAYER (the top layer above the background. Make sure you have a default workspace open [Window-->Workspace-->Default Workspace]) onto the picture you opened.
Play with the opacities, layers, and blending modes. You can create some really cool stuff if you just get creative.
*Sorry this isn't an action! And for some odd reason, the girl who took the stock photo of the car took it out of her stock gallery, but I'll keep the link there anyways.
