More and more I'm taking notice of photographs that have had a high degree of manipulation, post processed until they no longer represent the picture that came straight out of the camera but rather something that is a combination of representation and imagination. Digital Art. Some photographers recoil at the idea of any manipulation further than tweaking the levels or cropping the composition. I think however that there is no right or wrong in Art, it is what we define it to be.
