So here is the problem. If Lightroom as well as Adobe dng convertor used compress format what is happens with different type of files when convert them to dng? Also you really can't do metadata & preview update because files get converted to compress format. So how can save changes to dng except catalog?
If I shooting compressed what I never do, files ~45mb. But uncompressed 75mb. Only after Lightroom conversions or metadata & preview updated size shrunken to 45-47. The same situation with M9 DNG. From 18.3 to 8-9.
Well,
I’m shooting uncompressed DNG files. They are 75 mb in size. If I import them in catalog as copy, size remained as 75mb. If I import as copy DNG or after files in catalog and I select update DNG metadata and preview or export to DNG files shrink to 45mb. Both versions of lightroom . 4.4 and 5 beta
