The second is compression of the finished image into a JPEG, which happens after all of the processing outlined above happens. You won't be able to compensate for this after the fact because you can't change the exposure. There's an 'Active' flavor of this feature that adjusts the camera's exposure program for maximum dynamic range after the processing happens. This is the same thing done by the Fill Light control on some processing software does. Nikon's more recent bodies have a feature called D-Lighting that lightens the darker areas in the image. Your best bet would be to work with a few raw images and their camera-produced JPEGs side-by-side to see if you can find a set of basic changes that work. This normally involves setting white balance and applying some combination of adjustments to sharpening, contrast, brightness, hue and saturation. The first is how the camera enhances (or attempts to enhance) the image after it has been captured. There are two major categories of changes you need to deal with: You can, with some experimentation, approximate it.

I'm sure Nikon knows, but I'm also sure they're not telling beyond what they cover in the owner's manual.

A thumbnail, a smaller JPEG file for quick viewing, and the sensor image data. The structure of RAW files, including the ISO standard RAW image format ISO 12234-2, follows a common pattern - a short header, camera sensor metadata, image metadata such as exposure settings, camera, and lens model, date, and sometimes the location. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography. RAW image formats are intended to capture as closely as possible the scene's characteristics to include light intensity and colors. RAW files are named so because they are not yet processed and ready to be printed or edited with a bitmap graphics editor. RAW file formats contain minimally processed data from the digital camera's image sensor - the metadata includes information about the lens, the settings, the camera's identification, and other data. NEF, otherwise known as the Nikon Electronic Format, is Nikon's RAW file format.
