Those are pictures. You may, or you may not, like them. That is just fine. It is every ones right to have an opinion, and in the free parts of the world it is also every ones right to voice it.
It is also reasonable to question why DPReview shows them, if that is what you think. It might even be reasonable to question why the photographer spends time doing those (in your opinion) lousy pictures.
But the posts here go way beyond that. It is pure hate, against the art form and the photographer personally. “He should not be allowed to touch a camera again” – etc, etc, etc, …
As you may have seen, I am one of those that likes some of the images. And there are actually other here that do. So, it seems like they have some kind of value after all.
My advice – do not tell others what kind of images they are allowed to take. And if you have some critique – be nice. Someone may dislike what YOU do.
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
