Can someone offer some insight into the Lightroom function, Copy as DNG? (I'm on 3.6 at the moment.) I'm familiar with DNG (digital negative) as an open standard, versus proprietary RAW formats. However, I shoot a Ricoh camera which already produces a DNG. When I advertently invoked this feature, it copied my DNG's and made them smaller. I would expect this when converting from something proprietary, but to go from DNG to DNG and have the file size almost cut in half was a surprise. I restored my originals because I wasn't sure. If it's a lossless compression, however, I might be interested.
Does someone know? Nothing I'm finding on the web addresses this specifically.
Thanks. |
