We are all inundated with over saturated and HDR photography now but all this is, is the photographer attempting to make the shots surreal. Most people don't want their pictures to represent "reality" but instead a hyper reality or a dream reality. We can bemoan this trend but almost all acclaimed black and white photography is also tarted up to do the same thing.
Ansel Adams photography was not what was there but was his vision of what the scene could be. All you have to do is look at his darkroom work to see that the over dramatization of the scene was his goal.
Look at some of the black and white on this site and you'll find the same thing. Surrealism of a scene.
When I look through the viewfinder I don't go, "oh this look nice", I go " lets see, I'll darken the sky, make the clouds more contrasty, burn in here, dodge here" etc etc.
Even color photographers of the past tarted up the saturation and "impact" of the shot.
So what we are seeing a lot of now, is not new. We are just seeing more of it because there are more photographers out there.
