Eric Chan a while ago posted some new camera matching profiles for certain Nikon cameras. My D300 is one of those. These fix the highlight rendering issues I identified before. I beta tested them a while before they were posted and they are great. Below is an example where it really matters. This is a waterfall I photographed shortly after sunset last weekend. Development is completely standard, except for choosing the camera standard profiles. This image was taken in Eldorado Canyon State park. Click on the image to get a larger version. Focus on the highlight detail in the snowy bank just right of the middle
Nikon D300, ISO 200, 62 mm on Nikon 55-200 f4-5.6, f/16 2.5 sec - tripod.
The left image is the standard camera standard profile in Lightroom. The middle image is the v3 camera standard with -0.5 exposure compensation as required to get the correct rendering. The right one is the Capture NX rendering. You can see that the old profile washes out the highlights quite badly, while the new profile, similar to the CNX rendering gives a lot of detail in the highlights. You cannot correct the left image with highlight recovery or negative exposure compensation and get this detail back.
Of course, the bland, default rendering is not how I develop the image in the end but I just wanted to illustrate the effect of the new profiles.
EDIT. Here is a closeup of the v2 and v3 renderings in the highlight area. The effect is quite major as you can see.
