Considering that ACR now supports compressed RAW files from the new Sony A700, can anyone at Adobe clarify if the cRAW (compressed RAW) files are lossy or lossless. I would ask Sony directly if I knew how.
I did not promise to tell you if the compression is lossless based on that file. I asked for a copy as a favour, for I'd like to take a closer look at such a file.
Perhaps I can determine the kind of compression.
