I think he means bad in the sense of "8:1 compression means poor quality photos which shouldn't happen for a photo site" rather than bad in the sense of "google is doing something wrong, immoral or illegal".
- chias 11y agoIt's hard not to get 8:1 compression when we're starting from a RAW file
- 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.
