Do you use the same camera for both the colors and b/w's and just digitally take the color out or use two different cameras?

Jeff, in fact, this is the exact same photo as the one posted on my color photoblog. For the black and white version, I simply made a copy of the file and converted it to black and white. My camera can take photos in black and white, but I prefer to shoot in color and then use Photoshop to convert it to black and white since I can better control how the conversion is calculated.

That's neat. We have a painting in our bedroom that is a close up of a white rose (http://www.ikea.com/PIAimages/30503_PE119086_S4.jpg) set on a dark brick red wall. I have been thinking about taking a couple b/w images of the painting, printing smaller versions to hang on either side. But I wasn't sure how a b/w image of something that is mostly white would really look all that different. I have Photoshop, but am a novice. I am curious how you control the conversion?

Hmm, I like both :)
