There is no such thing as a natural photo. Whether intentional or not, every photo is an interpretation of reality. Cameras don't see the same way our eyes/brains do. I don't think I've ever seen a photograph that was "plausible as a real life eye view." I'm always aware I am viewing a photograph rather than the actual scene.
What is included and what is excluded from the frame is an interpretive decision. So is the perspective that results from the selected shooting distance.
The aperture selected that determines depth of field creates a certain interpretation. The same exact scene shot with a 300mm lens at f/2.8 will look entirely different than that same scene shot at f/16, especially if there are large differences in distance from the camera between the nearest and most distant objects in the field of view. Which interpretation is natural and which is not natural?
How long the shutter is open can be very interpretive depending on how static or how much motion is in the scene. Which interpretation is natural and which is not natural?
How bright the overall exposure is as determined by the combination of shutter speed, aperture, and sensitivity (ISO) can greatly alter the mood of the scene. Which interpretation is natural and which is not natural?
Even the amount of noise or distortion introduced by the camera or lens can alter the interpretation of reality created by a photo. Which interpretation is natural and which is not natural?
All of those interpretive decisions have already been made at the time the shutter button is pressed all the way down! We could go on and on about each step in the editing process as well. And editing a photo, whether in the darkroom or at the computer, has always been an interpretive process.
Just study the differences in prints Ansel Adams made of Moonrise, Hernadez, New Mexico over the years. He took the image in 1941 and produced over 1,300 prints from the negative over the course of his life. It is probably his most well known image, and certainly the negative from which he produced the most prints. The prints he considered the definitive versions weren't made until the mid-1970s! He spent 35 years fiddling with it in the darkroom before getting the look he wanted from the scene he recorded in 1941! Yet Adams is often cited as one of the best examples of the straight photography movement!
