Samsung RAW and Adobe DNG compared file size
I tried this on a 26.283 KB Samsung NX10 RAW file :
- Compressed with WinZIP : 23.599 KB
- Compressed with 7ZIP : 20.706 KB
- Converted to DNG format with Adobe DNG Converter 8.3 : 12.709 KB !!!
Given there is a 4.647 KB JPEG file embedded within the Samsung RAW file, the RAW data + metadata are about 21.636 KB in size, still much bigger than the DNG file...
Why is the DNG file so small ? Is the conversion process lossy ?
Thank you for taking the time to clarify this.
