Originally posted by peterh337 My view would be that a camera should produce an accurate image. No more and no less.
Cameras have no concept of images, though. They capture data, and that data is useless to the human eye. It is always interpreted in a certain way, given a white balance, processed (noise, sharpness) and so on.
Cameras record only one aspect of reality (certain light wavelengths hitting the sensor through the lens), and that data then gets interpreted, encoded, recorded and later it is decoded, post processed, and rendered. (the chain is roughly like that, there are many steps throughout if you want to get really technical)
For example, our eyes/brain adjust WB automatically. We just don't notice it. In reality, some rooms are horribly orange, and some are very very blue. But after a moment we adjust unconsciously. Cameras have some algorithms to try to mimic that. But they don't "know" what is correct. So they need things like color profiles and white balance adjustment. The second part is that photography is not just documenting reality, but rather is is creating an image with specific intent. Often this intent is to make a beautiful image
