What exactly is digital photography? To be honest, I don't believe it exists. There is no such thing as a digital photographer, you are either a photographer or you are not. It makes absolutely no difference whether you shoot on a Nikon D4, Nikon F55, a Holga, a Diana or a large-format bellows camera. You take the photo, not the top-of-the-line digital camera or the plastic 120 roll film camera.
This might just be why I believe that the new apps such as Hipstamatic, Swankolab and Instagram are such a perfect way to show this.
These apps fake the looks of the olden days in a pocket-size digital camera on which you can make absolute no setting changes. This makes it all about what you think is a great photo and not about technical skill. All this might explain the title of the book, digitalphotography?, in which the question mark plays an important role.
This all might just be photography pur sang, but about that I am not quite sure...
