Then do another jump with the Google Camera Mod and HDR+ (in my opinion at least on par with the OP6 and often even better quality).

I am using the Square Jellyfish mount (the metal one). Quite an awesome mount and fits my existing tripod well.
Thanks! I'm by no means an expert, so when I edit DNG I tend to just make a few minor tweaks in Photoshop Express like pulling down highlights/changing the color temperature and tint/noise reduction (not free, but you get a trial of noise reduction and "Defog" if you make a Creative Cloud account).
Noise reduction can be pretty useful for DNG editing since you aren't getting the usual JPEG noise reduction processing.
