@AWPStar Great work ,that's Quick ! I can comfirm works in A.E. cc , PS cc & PS cc 2015 but Not Premiere Pro cc , Premiere Pro cc 2015 & Speed Grade cc 2015.
Dose not open in Preview on the MAC , Plus the Size is Wrong , should be more like 3 Mb image not 800Kbs , therefore you have Compression and by the Mac preview
Info it has "Zip" compression and that the problem , Kill the Compression and it should work .
I see it in the "tiff" tags
'Compression
i = addtag( 259, 3, 1)
memcpy @FS[i], @Compression, 2
but I'm not sure , I think "1" for Uncompressed
Found this now, Have a look
EXIF Compression Values you have
"2 = CCITT 1D" for compression
"1 = Uncompressed" so yea if you change that to "1" for Uncompressed then it should work fine .
edit: I also notice you are using "DNG Version 1.2" not sure that a issue but the ones that work have been either 'DNG version 1.1 or 1.4"
