The dng files have a 960 x 640 preview jpg inside the dng file.I just noticed on my Air 2s when I save to .DGN format the images are only 960 X 640 resolution, as opposed to std. .jpg format they are 5472 X 3684 resolution (20 mp). I realize there is much more dynamic range in thev .DGN for exposure but 5.7x smaller resolution? Is this correct, or am I missing a setting in the DJI software?
If you are using non-specialised software that cannot read the dng file like checking with WIndows properties, it's going to show you the jpg preview and it's pixel dimensions.
