Shooting at base ISO 100 with ideal ETTR exposure is always preferred, but shooting at higher ISO can become necessary, e.g., handheld shooting and/or keeping exposure times (even on a tripod) from becoming too lengthy.
This page evaluates whether it is better to raise the ISO in camera versus shooting at base ISO 100 with a push during raw conversion. Which approach delivers the best image quality? In-camera processing for high-ISO presumably should bring to bear all the smarts the camera designer has to offer, including (potentially) characteristics of a particular sample of the sensor.
- ISO values 200 is amply 'clean', so it is omitted.
- ISO 400 versus ISO 100 with 2-stop push.
- ISO 800 versus ISO 100 with 3-stop push.
- ISO 1600 versus ISO 100 with 4-stop push. ISO 3200 (not shown) behaves similarly, only more so.
- Fake ISO values 6400/12800/25600 have other considerations, so they are omitted.
