He does good work. And, his rebuttal is sound.
It is sad to see "amateur fetishists" with their sloppy logic and lazy reactionary conflation of content and aesthetic seeping into the ranks of so-called professional critics, but I suppose it always has been the case.
The photographs have depth, pose questions, and obviously elicit reactions on several levels.
Mr. Winter is to be congratulated.
As to why he won, perhaps it is important to remember that photography didn't begin with Daguerre or Niepce, it started with something thousands of years earlier - the first glimpse in a reflecting pool perhaps, where someone was struck with the desire to reproduce something that they saw. The rules about what constituted valid formalism came later. Much, much, later, and at the hands of those who sought to codify what had already been produced.
It may help to look at it as a picture rather than a photograph.
