Photography is a process of selection and abstraction, a series of them at that. First, we put frames around a frameless world and choose one from among an infinite number of them. Then, we flatten the three-dimensional space to two dimensions. Third, while our eyes can focus only on one thing at a time, we can bring the entire scene in sharp focus. Then we remove the color. All this, before we even deliberately try to achieve abstract results.
Then, someone comes, half cocked with earful knowledge about digital photography and pronounces that it is no good because: it is manipulated.
