It seems to me that your friend takes a much more modern approach to photography than the more traditional, meaning a lot more post-processing than what is really necessary -- overdone. In the photography and fashion world, the French call it "de façon exagérée" meaning "exaggerated fashion".
I've studied photography for years, and HDR isn't really a new concept. The first HDR imaging was done in the 30s, by a photographer named Wyckoff. His images were popularized in Time in the 50s. It wasn't until the 80s and 90s when HDR technology truly became available in professional realms (it didn't hit hobbyists/amateurs really until Photoshop CS2).
Once it became mainstream, really every photographer had to do it, and ultimately it has changed the face of photography as we know it. You might think that sounds stupid, but, consider
the first color photo ever taken. It was a new way to capture the world around you. HDR? A new way to capture the world around you.
The photographer here has the eye, but after viewing his other works, it doesn't seem he quite has it yet. He has clearly been doing this for years, however, I feel that he is focusing entirely too much on the post than on the photo itself.
They are good photos and the girl a weapons-grade blonde bombshell, but, I just feel that these photos would have so much better if they looked a little more classic. She really has a classic beauty to her. I am thinking the post processing ruined her skin, the fake tan helped too. These photos are unbelievably LOUD and maybe she wants to make a statement.
But, the glory of art is that it is beautiful and subjective. I like these photos, but, I would have liked to see her, the car, and a big cornfield behind her. Maybe do some B&W photos, but drop the HDR/post processing mess.
