Hi all - can someone give me a quick tip on accomplishing the following in Photoshop CS 5.5, or connect with a how-to? I have a color photo shot in RAW of a red firetruck in front of a crumbling old neo-classical building. I'd like to leave the red body of the firetruck in vivid red and convert the rest of the image to B & W. In Camera RAW I can reduce the vibrance to achieve nearly the effect, however the red in the truck becomes much less vivid and is not the effect I want. Any tips! Much appreciated.
