Lightroom CC now offers HDR processing. This is significant because you no longer have to export your files to NIK HDR, Photoshop, or Photomatix. When you use the Lightroom CC, the output is a 16 bit DNG file of considerable size and sharpness. You can process the DNG in Lightroom CC, and the exposure latitude is now 10 f/stops in either direction. The other basic controls work the same as with a non-HDR image. The LR HDR DNG file looks the same as the middle/normal file you used to create the HDR. I think there is a minimum of tone mapping in Lightroom HDR, and if you have a large dynamic range you are trying to capture, you may get better results with NIK HDR. But there is no color or structure or contrast added with the LR HDR, unlike the NIK.
