Does NG publish the RAW no-manipulation photos or does NG post-process before publication?
Good point, Isaac. An unprocessed RAW file is just a pile of numbers. To translate such numbers to a recognizable image requires a lot of sophisticated processing, the details of which most of us don't fully understand. At least I don't claim to understand the precise details. I haven't got the time nor desire to involve myself in all the technical minutiae of photographic processes. I'm more concerned with the broader issues.
What seems clear to me in a general sense is, from the moment the light, as reflected from the subject one is photographing, reaches the front element of the camera lens, a whole lot of distortions, bending and corrections take place before the photons of light even reach the digital sensor or surface of the chemical film.
Once the photons have reached the sensor or film, a whole lot of other complex processes take place. In the case of film, the photons of light knock a few electrons off the molecules of silver halide compounds, reducing them to metallic silver. Such changes in the chemical structure of the film coating subsequently show up as a recognizable image when the film is developed.
In the case of a digital sensor, those same photons of light again knock off electrons, but this time from silicon, resulting in a specific electrical charge at each of the millions of pixels (or sensels, or photosites). Such electrical charges, through a complex process of conversions, amplification, noise reduction and subtraction, and much electronic manipulation, end up as a series of numerical values which are written to the camera's memory card as a so-called RAW image, and/or a compressed jpeg, which is really no image at all, just a bunch of numbers.
In order to see the images represented by such numbers, a whole lot of additional processing and conversions have to take place using sophisticated computer programs, both in-camera, as when viewing the shots on the camera's LCD screen, and during post-processing when viewing the the RAW files as converted by an external program.
If the result of all this automatic processing happens to match reasonably well what one remembers seeing, then I guess one can consider oneself lucky, or maybe one just isn't fussy and adopts the attitude that 'close enough is good enough'.
