I took some HDR photos (RAW+JPEG) with my phantom 3 Pro yesterday and when i looked at the DNG files from the card, the darker/underexposed areas were filled with blue dots. The JPEG photos were fine.  I used the DNG cleaner on them and still no luck.  They were opened up both in Adobe Lightrrom, Photoshop and Apple's Photos and all three showed the same issue.  I have not tried shooting just a regular photo of (without HDR) using the RAW setting yet.  If it comes out clean, does that mean the HDR feature while whooting RAW screws up the photo?

Thanks,
David

The built-in HDR feature isn't very good.
If you want to shoot  HDR just use AEB bracketing to shoot brackets of 5 and do the HDR yourself in the computer.
You'll  get much  better results.

I have the same problem just with red and blue dots (see picture zoomed in). i get these dots every time i make hdr photos. So just like you said, is it just because of the hdr feature?
