What is a little worrying though, DNG is approx 15-20% smaller than CR2. What's getting hoyed out when you convert?
Coming from a computer background it could just be an improved lossless compression algorithm. A bit like going from Zip to Rar. Better compression usually (not always) means slower compression/decompression.
If it's using a lossy compression to achieve this, then it can fook off.
Confirmed, it's lossless
, which is good.
I have the latest Windows 7 64-bit drivers for DNG. In Windows explorer and Windows Live photo gallery the image is corrupt when converted from Lightroom 4.
I've tried it in Google Picasa 3.9 application which uses it's own internal drivers, and it's corrupt too.
Windows photo viewer is fine.
