In my last post I wrote about how I started "scanning" my B/W negatives using a rather standard DSLR setup. And sofar I have been very happy with the results! What I didn't cover was how to actually post-process the pictures, and I might not be ready to describe it now already since there are many lessons still to be learned. Nevertheless, I have already found some tricks which could be useful.
I am a big fan of Lightroom, and when used for this kind of work it really shines. It is not just for technical merits, it is also the close resemblance to the "wet processing" world of the darkroom. The simplicity and the "closeness to the photo" appeals to me a lot. So this story is how to do it in Lightroom, folks..
On the other hand I am not at all a big fan of lomography-style processing style with simulated light leaks, artificial grain and all those weird things. I like crisp and contrasty results, and now since I am using Tri-X film (pressed to 800) there is of course a lot of grain to handle. Grain is beautiful! The problem is to use it to your advantage, and this is difficult. I think I have found some tricks for this.
Let's first start with the curves in Lightroom. Since I am taking a photo of a negative, intending a positive result I will need to create an "inverse" curve. This is easily done by "tipping it" in the wrong direction. This will make black become white and vice versa. For color you flip red vs cyan, blue vs yellow, magenta vs green etc... Creating a negative of the negative! It looks like this:

As you can see the curve is reverse linear, but I have pumped up the mid-tones a little.
The next interesting setting is the split toning. I have a preference for a slight toning and like a blue tint to the pigment (blacks) and a little creamy yellow for the paper (whites). This is of course very much a personal taste, but this is how you do this in Lightroom:

And now on the sharpening.

I was a little surprised to find that this heavy sharpening was useful, but the film adds something which really likes a heavy USM to be applied to get the details clear and obvious. But the trick is to later on reduce sharpness in all areas of the pictures which feature soft areas and gradients. More on this later..
And finally the Basic settings. This is where you adjust blackness/whiteness, contrast and exposure. For all shots you will need to do final tweaks here. This is the default I use, and as you can see the picture gets a little underexposure (-0.85 steps) but actually this is an overexposure since you work with a negative!

Apart from the settings above you can of course tweak around with vignetting, lens corrections etc etc. All this is done at your discretion and according to your taste. It is however a good choice to apply profile corrections to your lens, if these are available in Lightroom.
So where do we get then? To make it easy you can download my current fave preset for B/W negative shots
here! Just install it in your copy of Lightroom (version 4 needed) and you have my settings ready to use.
And now the final and important technical and artistical pain. How to handle the grain? Actually my rather over-sharped settings produce quite a noticeable grain and grain aliasing in many parts of pretty much any picture. For smooth areas you may feel tempted to reduce this effect to create a more calm expression in your image. Well, don't just feel tempted, just do it! This is so easy with Lightroom! Just create an adjustment brush and set the "Sharpness" value to something like "-30" and paint the smooth areas. This will make a drastic improvement of the grain artifacts in those areas, making the grain softer.

Let's take a look at a detail in one of the pictures I worked with.
First without the adjustment:

As you can see the ligher parts of the water surface are quite heavily affected by grain. Let's paint this surface with the "-30 sharpness" brush and keep the darker surface (with the small snow balls) intact. Now we get this:
