The problem comes when a person attempts to use carefully selected images to mock other people, which rather appears what the photographer is doing here.
the photographer found a theme and used it to his advantage. that's what some, if not most, photographers do.
as for the flickr selection. one realizes that the photos are not really that different from one another. half way down page two i gave up.
some well framed shots among them, good colour, sharp... and in some cases, with willing participants.
it's not the photographer who should be ashamed, it's cardiff.
