I noticed that too, and it drives me insane.
The Photos app received an update and can now view DNG Files.
This causes the duplicate images.
22MB is the DNG file (you can even see it in the file name) and the lower one is the regular Jpeg.
The linking only happens with OneDrive.
For instance:
I take a picture, my camera takes the 22MP DNG and the downsized Jpeg. Both will be uploaded to OneDrive.
IF it is an HDR image, I get the additional brackets, too.
I end up with 5 identical pictures in my library with no way to filter them out.
I WISH Microsoft would add the functionality to OneDrive AND the Photos app to check whether I want DNG files uploaded AND shown....
Has anyone a fix for that?
Only Solution I found so far is copy the DNG files to my NAS from time to time. But that is tedious and I don't want to change camera settings all the time.
PS: Not on an insider.
My girlfriends Lumia 640 is on Insider Fast build and doesn't show this behaviour - but on the other hand I haven't seen her taking any pictures with HDR enabled. Must check that today.
