Do you know what is being done to the data between coming off the sensor and being saved to a RAW file? My impression is that other than dead/hot pixel mapping and some degree of noise reduction, not much else is done (at least in Canon-land).
Even if the camera can do more post-processing, I am not sure I want it to. I would rather the camera do less after exposure is complete, so I can get more control over it while editing.
- tambourine_man 8y agoAt the very least there’s signal amplification (and possible highlight clipping) at higher than baseline ISO. Otherwise you'd get a very dark image indeed.
- frankchn 8y agoAh of course. I assume that is done pre-ADC though, so it is part of the analog circuitry on-board the sensor?
