PureRAW gets around this by creating a ‘Linear DNG’, which is like a part-processed RAW file. You will also be dependent on the effectiveness of your software’s lens correction tools, if it has any, to fix issues like corner shading, distortion and chromatic aberration. The trouble is, raw processors are not all equally good at this demosaicing phase, which is one reason why raw files can often look a lot noisier than in-camera JPEGs if you are an Adobe user. They can then exploit the full range of tones and color information in this raw file for editing and enhancement. Regular raw processing tools take control of every stage of raw processing, including ‘demosaicing’ the red, green and blue pixels captured by the camera sensor to produce a full color image.
