Whether I decided to go with what the camera does to my composition "as-is", whether I manipulate that in the dark-room or with Photoshop, and whether print the photo or the digitally manipulated painting, frame it and call it done then or I move on to represent the image in paint, and what I do with the paint are all my choices. The image and the object at the end are the product of my "authentic" authorship no matter where I stop and say "done."
When it comes to digital photography I do draw a line between what's a photograph and what is a digital work. If my Photoshopping involves no more than basic darkroom manipulations or things I could have done with filters on the camera (e.g. cropping, changing the contrast, changes in saturation and tone) I continue to call it a photograph. If my manipulations involve more complex manipulations it becomes a digital work. Still, though, the line is shady... your dodge and burn example being on that line. If I split an image into layers and mess with the histograms and focus in the layers separately I'm not doing anything that couldn't be done in a darkroom, but it's not anything I'd personally want to do "the hard way" so I'd be inclined to call the image a digital image after that rather than a photograph, but either way it still doesn't change the authenticity of the piece.
