In an article on Digital Photography School the author says
The camera is an instrument that records exactly what is there, without judgment or interpretation.
I must respectfully disagree, because a camera always interprets – alters – what is “sees”. There are many factors involved in this interpretation including shutter speed, aperture, lens (extreme example: fisheye lens), focal length, film (think about black and white), sensor, and processor (the computer in a digital camera which processes the data coming from the sensor). Just as an interpretation of language never captures the full nuances of the original speech with all its cultural connotations and subtleties of meaning that a native speaker would pick up, so does a camera never provide a true and full rendering of a scene that matches what we would see when viewing the same scene with naked eyes. If you put on rose tinted spectacles they will interpret or alter what you see, just as viewing a photo puts an interpreter/camera between you and a scene.
Consider these two examples (clicking on a photo will enlarge it):
The great thing about photography is that we can control the interpreter – the camera – and make it produce a pleasing interpretation of a scene: that is the skill and the art of photography. This where previsualisation is invaluable, i.e. knowing what you want the final result to look like before you pick up your camera/interpreter. When you know what the destination is you can guide the interpreter accordingly. When I was watching the people that you see below I visualised a photo with silhouettes, lots of motion blur, drama, and a strong sense of movement. In closing, this is the final interpretation of that scene, which looks completely different to what I saw at the time*:
* The great thing about digital photography is that it is easy to continue the interpretation process on a computer, as I did in this case when I converted to monochrome (black and white). Apart from that what you see in this photo is essentially what came out of the camera.
