No the ISO setting works in the analog domain, amplifying the signal prior to digitisation, so it is different from digital postprocessing. Edit: apparently my knowledge on this is outdated.
- hug 9y agoYou had it right the first time. ISO on most cameras is very much implemented via analog gain up to a certain point, beyond which "digital gain" is applied.
- Aeolos 9y agoOne thing to note is that most cameras use 12 or 14 bit sensors, so in-sensor digital gain can still be better than post-processing.
- StavrosK 9y agoYou mean if you shoot JPEG, right?
- hug 9y agoAbout the only camera that I know of that will currently saturate the bitdepth of a 14-bit ADC/RAW with DR at base ISO is a Sony A7S II, so right now, yeah, shooting in JPEG is the real issue. This will change in the next few years.
