The Reichmann-Schewe download (Lightroom 3 video tutorial) from this site's web store I think is the best Lightroom resource of its kind. That said, there isn't much to creating a great B&W rendition in Lightroom. Go to the HSL panel, select B&W and play away. Each colour slider changes the luminosity of the colour group underlying its grayscale area of the image. "Slide to taste". Or start with any of the large number of B&W Presets in the left side panel of the Develop module. You'll learn by doing how to make very pleasing B&W images in little time.
Thanks, Mark. To date I've been using Photoshop Elements with Silver Efex Pro, so I'm familiar with pre-sets (in SEP) and in fact rely on them extensively. (I've been told that I can also use SEP with Lightroom as a plug-in, but haven't yet been successful in managing that.) With my interest in trying Lightroom as my primary black-and-white processing software, I was interested in gaining the extra aesthetic flexibility that might be available to me there without using pre-sets (although pre-sets are certainly easier, and do establish an advanced starting point for later refinement of an image). In the books I've been reading, while I find they are occassionally beautifully written, I often find their instructions somewhat opaque. As a lawyer, who values written precision, I am often frustrated and confused by these texts. Anyway, your advice is good. Again, thanks. Jim
