| stoft | "But that was part of my point -- the camera does 'raw-capture' processing on the sensor's 12-14bit detector data before it gives you the 'raw' data..." | Read more » | almost 8 years ago | |||
| cfastie | "I think if you capture camera raw you have a single number (DN) for each pixel and you know what kind of Bayer filter that pixel was under. The DN ..." | Read more » | almost 8 years ago | |||
