Every photo from the iPhone camera goes through Apple's AI processing first. Frames are merged, noise is smoothed, edges are sharpened and tones are set before you ever see the file.

RawCam skips that. By default it saves what the sensor captured as a Bayer RAW DNG, so you decide how the photo looks: pick a look as you shoot, or develop it later in the app. The RAW is never changed. Download it for free, no account required.
