You can set the D7000 (my first "modern" DSLR - a D40 prior to that) for 16 bit. For Image Quality, I only use "Normal." If you are using either LR or PS, you can set the RAW editors for 16 bit (in the RAW editor, open an image for editing. Just under the image you will see (at least in Bridge) a blue line of information. Click on that and change the bit edit to 16. In Photoshop (I don't use LR), go to Image, Mode and change that as well to 16 bit. IF you do your editing in PS, you can open all three exposures and then in the File, Automate, Merge to HDR Pro which is a 32 bit editor...oooh, and it really helps the HDR. It's a little tricky but you can do a youtube search on 32 bit HDR pro and follow the directions. You can tone map in PS or since it's free, you might want to try Google's NIK package.
