Hi everyone, great forum!
Guys, I am not specialist in photograph or image acquistion. I have a question, maybe a dummy question. I have looked at the specifications of raw files of several cameras. For instance, the Nikon D300 says that files can be saved as either uncompressed or compressed raw. My question is the DNG file compressed or uncompressed raw? if that makes sense, anyway. I mean, is there any losses by DNG coding? In my case, I need to make sure that edge information is preserved.
Thank you guys!
You can save compressed or uncompressed DNG files. They are both non-lossy, no data or image quality is lost in either one.
The difference is that compressed DNGs occupy less disk space, but they are slower to open and save.
