소니 미러리스에서 14bit Raw가 유지되지 않는 설정

다음과 같은 설정에서는 12bit가 된다고 합니다.
단 A9은 확실하지 않습니다.
조용한 촬영
장노출 NR을 켜 놓았을 때
벌브 모드(30초 초과시)
연사
그 밖에 현재 5초 이상 노출시 star eater 현상도 있는데 펌업으로 고쳐질거라는 루머도 있음.
Silent Shooting
*I would turn this mode OFF for critical work
Long Exposure NR (when the camera automatically captures a black frame after the exposure)
*I would turn this mode OFF and capture a black frame instead
Bulb (more than 30 sec. exposure)
*Once you pass 30 seconds your files will gain 1-stop more noise and h에이브이e 1-stop less dynamic rage. If you are doing Nightcapes and need ISO 400 or higher, the noise increase from the bits reduction will be unnoticeable according to the article below. Another workaround is to take several 30-second exposures and stack them in Photoshop as Smart Object –> Stack Mode -> Summation. So (2) 30-seconds stacked this way will end up looking the same as a 1-minute exposure.
Continuous Shooting. (Including Bracketing continuous shooting)
*When using Bracketing, do not set the camera to continuous shooting
