X-Pro-1 Test shots in B+W and color
Regarding what filter to use for B+W, that depends entirely on the contrasts in your scene and which elements you'd like to emphasize. In practice, I found that in most cases, a mixture of 'filters' is what's needed to get the best result. Proper B+W, IMHO, is best done in post processing, but that doesn't mean you can't get decent results out of the camera under certain circumstances. If you want to do post-processing in the camera, then I'd suggest you play around with the options until you have an image that you like. Keep in mind that there might be more than one way to render an image.
