So uh compressed raw would be just like a regular (loss-less) compressed image format, then? I thought the distinction between raw and non-raw was the use of lossy compression formats like JPEG.
- Espressosaurus 3y agoRAW is in linear light. Think spring-fresh, straight from the ADC. JPEG is in perceptual (~log) light. Out of the tap, terrible. It's also compressed. There are lossless and lossy compressed RAW formats.
- andybak 3y agoWow. The tap water isn't so good, where you are then?
- dagmx 3y agoRAW doesn’t denote compression, contrary to the name. In Still cameras, it usually means pre-debayering. On film cameras, it is a little more muddled but usually just means linear colourspace and higher bit depth.
- ryandamm 3y agoIn the case of red’s patents, the relevant issue for RAW compression is that the sensor values are compressed before de-bayering. It’s still lossy.
