The primary technical advantage of using a third-party camera app for manual ISO control over a native camera app's Night Mode in a challenging low-light video shoot is the ability to achieve consistent and predictable exposure and image characteristics across all video frames. Manual ISO control allows the user to precisely set and lock a specific ISO value, which represents the camera sensor's sensitivity to light. By fixing the ISO, every single frame of the video footage is captured with the exact same light sensitivity, resulting in uniform brightness, a stable noise profile, and consistent grain throughout the entire video clip. This consistency is crucial for profes....
