- ygra 11y agoRaw already is compressed. My 40D takes raw files around 12 to 15 MiB. They vary in size, so that's a first clue. Also, if you do the math, 14 bits per channel on those images comes out around 65 MiB.
- Ensorceled 11y agoMy understanding is that most RAW formats such as CR2 already had lossless compression applied, so any compression would pretty much have to be lossy to some degree, especially a 8:1 compression.
