Editing is a choice made by the photographer and therefore completely up to their personal taste. Many photographers and many schools of photography will teach you that over-editing is bad and results in bad images, but that may not always be the case. Over-editing is a choice and if the client of the photographer likes that kind of editing then no matter how much the greater photography fraternity screams and shouts, the resulting images are accepted by those clients and the photographer will be happy. It is very much like death metal music, it is not everyone’s cup of tea, yet it does not go away just because the majority of the music industry does not subscribe to that style.
Even I, when the mood strikes me and I come across the right image, will do an over-the-top over-edit (normal edit is always included as well).
