Cameras are designed to be able to record much more information in a single file, or a single frame of film, than what our eyes can see, and our brains can render and store as a memory an event that happens in the blink of an eye.
With cameras this only works if one learns to best use their camera settings in both digital or analogue to get the most information possible on each frame. Seldom does a camera or analogue film render exactly what we saw with our eyes,whether using auto settings or personalizing settings for effect, but that information is on most those files, and can be extracted by enhancing or detracting, and adjusting parts or the whole of them. That's what most editing is is all about.
There's also a more creative aspect to post production where the information can be used to create an alter-realistic, hyper realistic, or a dream like image, or to add characters and other imagery in overlay to create 'paintings' that represent the artist's imagination in visible form.
With analogue, double exposure can be used, and some digital cameras are now being produced with this capability. Just another tool to be used for producing artwork.
No-edit might be fine for family snapshots and vacation memories, or where lomo cameras and lenses are being used for their individual characteristics, but to produce most art images requires the freedom to use whatever tools and file information the artist has at their disposal.
I think now, I've said more than enough on this subject. I will remain silent about it from now on...
