You can’t not post-process a photo, because you can’t use/view the RAW file captured by the sensor, or better, only the company who build the RAW/DAC conversion

You can’t not post-process a photo, because you can’t use/view the RAW file captured by the sensor, or better, only the company who build the RAW/DAC conversion can issue the “codec” to open the RAW file.
The issue is “how many interpolations/adjustments are these companies making when converting the RAW to an image file?” Too much according to the article.
- kevingadd 4y agoI think it's important to distinguish between signal processing techniques like debayering, auto-leveling etc and "we're using machine learning to identify humans in a picture and adjust their contrast". We can have the former without the latter, they're not all just "post-processing".
- happytoexplain 4y agoIt seems like an oversimplification to imply all processing exists on a gradient with no significant lines we can draw between one type and another. E.g. content identification has a pretty clear qualitative difference from whatever "dumb" mappings do to get from RAW to values in some color space. One isn't just "more processing" and the other "less processing", colloquially.
- ArtWomb 4y agoAndroid Camera2 APIs allow RAW capture. But images still require a bit of magic to "de-bayerize" added color filters and noise ;) https://en.wikipedia.org/wiki/Demosaicing https://en.wikipedia.org/wiki/Demosaicing
- shock-value 4y agoIt’s not just a matter of degree or quantity of post processing. Some techniques are qualitatively different than others.
- The_Colonel 4y agoThis is the type of pedantry which is technically correct, but contributes nothing to the discussion.
