Hi Michael, I believe the D-lighting is using sensor gain (ISO) or post-processing on brightness values to achieve the HDR effect, and since the D3200 is an "iso-less" camera, boosting the exposure in post-processing has the same effect on noise as increasing the ISO in-camera. That is to say, the single NEF file you have contains all the same information you need to create your own "D-Lighting," you would just need to boost shadows (or some other exposure effect) in Darktable.
You could also do a "true" HDR by changing the exposure (shutter speed/aperture) which would mean you actually collect more light in one of the exposures, which will reduce the noise in the shadows. But now you have to avoid moving between those two shots. Hope that helps! -Owen On Mon, Jul 25, 2016 at 1:56 PM, I.
