via the “Monochrome” preset discussed below
The tone curve is one of the ways that Adobe Lightroom offers to adjust an image. It's basically a “brightness map” that normally indicates "dim parts of the image are shown as black, bright parts are show as white, and things in between are shown proportionally somewhere along the line between the two". The screenshot below highlights Lightroom's default tone curve, which is mostly a straight line (that is, “proportional”) from dark to bright...

in the second LR3 public beta
Prior to the release of the second LR3 beta earlier in the week, Lightroom users could tweak the tone curve slightly to try to bring out or suppress detail in tonal areas of an image (e.g. “bring up the shadows”, “compress the highlights”, etc.), but now with we have much more control.
For example, those old enough to remember the real meaning of a “film negative” from personal experience will appreciate the look one achieves when using a tone curve that's been inverted — one that maps bright to dark and vice-versa — as illustrated in the next two screenshots...
(You might find the photo familiar if you saw my “Funky Joy with Adobe Lightroom” post a couple of years ago, about “negative clarity”.)
I've created a half dozen Develop Presets that allow you to do this and more; there's a download link at the bottom of the page. Once you install the presets on your system, they'll be listed in the aptly-named “Presets” section on the left side of the Develop Module, as illustrated by the “via this preset” highlights in the two screenshots above.
You can do some crazy things with custom tone curves, as the lead photo of my LR3b2 post shows. Less haphazard, but almost as crazy, is a pure monochrome treatment — just black and white; no gray — as illustrated with the following before/after screenshots...

As you can see, the tone “curve” above is a vertical line at the halfway-brightness mark: anything that's supposed to be more than halfway bright is made perfectly white, and anything that's less bright is made perfectly black.
To be clear, I'm not touting this as a “good” effect; it's fun to experiment and play, but whether it's good or useful is very much up to the specific situation and, like all artistic endeavors, the eye of the beholder.
But it is fun to play, especially with this monochromatic idea, because it has such a dramatic effect on the photograph. But “play” is important, because develop changes that make parts of the photo brighter or darker can move those parts across the vertical cliff of our tone curve, so even subtle adjustments can have sweeping, dramatic effects on the final image.
The screenshot that leads this post is another example. It's a photo from the same outing as this one, but it was way overexposed and I really should have just deleted it, but it turns out to make a great example here. I used a lot of the “Recovery” develop adjustment to bring some of the features of his face “below the cliff” (so to speak), so his face wasn't just a white blob on the side of a larger black blob.
It's similar to what I did with last photo in yesterday's post in that it rescues something of at least mild interest from an overexposed shot. I'm not sure what I'd ever really do with something like this, but like I said, it's fun to play.
But with the “subtle adjustments can have sweeping, dramatic effects” bit in mind, one can often get something interesting from regular shots. Here's a version of this photo from 2008 of Anthony with his friend Gen...

I've also included a “Monochrome (inverted)” preset that's the same as Monochrome, except it's upside-down, so the sense of black and white are flipped.
The monochrome effect can be fun, but as you can see, it's really stark. One step back is the “Monochrome (per color channel)” preset, which is the same as the “Monochrome” preset except that it keeps the treatment as color instead of B&W, so you get a strong posterization effect among the primary and secondary colors (as modified by other develop adjustments, such as white balance)...
Subtle changes to the white-balance setting cause all kinds of freaky, dramatic changes.
Going even further is to make it less stark by converting the vertical cliff of “monochrome” into merely a steep hill, thereby making the transition from black to white a touch more gradual. Compare the before/after of the next two screenshots...

The effect here, of some nature at Kyoto's spectacular-in-autumn Eikando Temple, is really interesting to me. Some of the colors are a bit too overwhelming, though, but backing off on a few adjustments, notably Vibrance, makes a real mood-setter:
There's a “Mostly Monochrome (B&W)” preset as well... compare these before-and-afters...

The key to these monochrome / mostly-monochrome presets is to play with the develop settings — especially Exposure, Recovery, and Fill Light — to adjust what parts of the photo fall across the cliff or steep hill.
Download and Install
First let me say that it's easy enough to create these tone curves and presets yourself. You can create the tone curves by clicking the “point-curve” icon in the lower-right corner of the “Tone Curve” section, then dragging the points around. The points can be a bit temperamental at first, until you get the hang of it; or better yet, check out this great LR point-curve tutorial. Once you've made a tone curve whose effect you like, you can save it to a Develop Preset (instructions).
But, since I've done it already, it's easy enough to share, so here's a zip with all the presets mentioned:
[ Lightroom 4 and later: see this warning ]
I also threw in a “Dave Hill” Look preset, and the “Dreamy Creamy” preset I used on this photo last fall. That's pretty much the extent of my preset use, except for some calibration presets I use during import.
After downloading and unzipping, right-click on “User Presets” in the “Presets” panel of Lightroom's Develop Module, choose “Import...”, and navigate to the .lrtemplate files left by unzipping.
Play. Experiment. Have fun.
